Description

SYSTEM FOR MANAGING DISPLAY OF INFORMATION BY MEDIA BASED ON THE DISTRIBUTION OF THE PROFILES OF TARGET PEOPLE PRESENT IN THEIR NEIGHBORHOOD

The invention relates to the field of the display of information, possibly of an advertising nature, intended for a public, or information relating to a given population, by means of display medium (s).

The invention relates to a method for managing the display

Lo information. The general inventive concept is that covered by the subject matter of claim 139 relating to the method, and applies to the associated system.

The invention thus encompasses the display of information by means of fixed supports, by means of at least partially mobile display medium (s), or by means of display medium (s) located in vehicles.

L5 public transportation. These various embodiments are respectively covered by the sets of claims 1 to 44, 45 to 94 and 95 to 138.

FIXED SUPPORT

At first, "display medium" is understood to mean a material implanted in a chosen place, fixed and intended to support a poster, possibly of an advertising nature, or to display information (or information), possibly of a advertising, then to maintain this poster or this information (or information) in a position

25 given and for a given duration so that it (s) can (s) be observed (s) by an audience located in its vicinity.

On-site advertising is traditionally carried by fixed supports such as billboards, in particular placed in very busy places (city boulevards, major highways,

30 interior airports or railway stations, facades of buildings not useful for housing, bus shelters, display columns, for example), or LED display screens or plasma, by example. These advertisements may have been affixed by gluing on the fixed support. There are also fixed supports with several posters scrolling in turn, or can be selected in a "tank" and displayed on the visible side of the support for a predetermined time. The invention relates to fixed supports for selecting one of several displays or displaying on a screen information, information, an image or a video clip.

The display companies (so-called billboards) have at their disposal display networks and offer their advertising customers qualified displays according to the target sought. The rating of the display networks is a standard parameter for advertisers and viewers through a particular nomenclature that generally divides the population into five social level layers (A, B, C, D, E): thus, if the advertiser is interested in targeting a cadre population, it will require category "B" targeting; a senior management population will correspond to category "A" targeting, etc. For example, a Category A signage network is often located in a large city, near business offices or residential neighborhoods.

However, the qualification of the display networks remains limited to the predefined categories and there is no other technical means of targeting the audience. At most, some advertisers may have surveys done on the spot, that is, close to the advertising medium, to know the profile of the individuals passing by and the impact that this advertisement has left in their minds. This single way of measuring targeting is very little used because it is expensive and provides the opinion of only a very limited panel of people (very) unrepresentative of the entire population. In addition, it does not respond quickly, given the time required to obtain and analyze the results of opinion surveys.

The object of the present invention is therefore to solve the problem set out above in order to provide a more precise targeting that is as much as possible in affinity with the passing public.

For this purpose, the invention proposes a system for managing the display of information on at least one fixed display medium, furthermore comprising: locating means responsible for determining the presence of target persons in at least one first known geographical position zone, located in the vicinity of the display medium and in which the display medium is in visibility of the target persons, the latter being associated with profiles defined by objective and / or subjective characteristics,

first storage means responsible for storing the profiles of the target persons,

calculating means designed to distribute in groups, which are each defined by at least one profile characteristic, the target persons whose presence has been determined in the first zone,

correspondence means responsible for establishing correspondences between the groups and information to be displayed, and

control means responsible for causing the display medium to display at least one piece of information corresponding to the characteristic (s) of one of the groups chosen according to the number of target persons that it groups together compared to those of the other groups, the selected group comprising at least two target persons.

The invention thus has a dual function, the first is that of analyzing the average profile of the public frequenting an area located near a display medium (for example, if the public has been previously qualified "AB", the the invention makes it possible to verify it, or even to refine the qualification), and the second is that of the targeting of the public according to the result of the analysis obtained, in order to provide to the public information corresponding to at least a part of its average profile.

In this way, the invention makes it possible to achieve the objective desired by any advertiser, namely the targeting of the public by micro-segmentation and the display of really useful information, thus ensuring the optimization of the advertisers' budget. The invention being based on the concept of groups, it makes it possible to provide a technical solution to the dual technical problem of prohibiting the use of personal data of target persons (such as users) and the technical unavailability, for some actors of the circuit economic, of this personal data in their databases. Indeed, because of the prohibition or refusal to commercially exploit this personal data, customer files can not be transmitted to economic partners, for example mobile operators can not transmit such files to customers. service providers. Due to the obstacle created by this unavailability, the targeting of the advertising data was in the reduced prior art.

It is essential to understand that the calculation, according to the invention, intended to distribute the target persons in groups, implies a priori a plurality of persons per group (the same target person can be in several groups at the same time, the profile characteristics used for the distribution are not necessarily exclusive). However, a group may be reduced to singleton (a group with only one target person). In this case, preferably, the invention does not automatically exclude this singleton group before the display. It is only during the control step responsible for causing the display medium to display that it will be verified that the chosen group comprises at least two target persons. The singleton group can not be the subject of the chosen group. Alternatively, it may be possible to automatically exclude all singletons before ordering. Therefore, it is ensured that the selected group will in any case be of a composition greater than or equal to two target persons.

The system according to the invention may comprise other characteristics that can be taken separately or in combination, and in particular:

Other features and advantages of the invention will appear on examining the detailed description below, and the accompanying drawings, on which :

In the following, the elements (or modules) performing identical or similar functions will have identical references.

Reference is first made to FIG. 1 to present an information display management system according to a first embodiment of the invention.

As illustrated in FIG. 1, a management system according to the invention comprises at least one fixed display medium SA, target person localization means ML1 and ML2 (or ML3 and ML4), a first memory MS1, an MCR correspondence module, a calculation module

MCL and an MCM control module.

In what follows we consider only the case of a management system comprising a single fixed display medium SA, in order to simplify the description of the invention. However, the invention applies to any management system comprising at least a fixed display medium SA.

Furthermore, in what follows, by way of illustrative and non-limiting example, the information to be displayed is of an advertising nature. But, the invention is not limited to this type of information. It also concerns the display of information relevant to a given population.

The display medium SA is fixedly implanted in a chosen location. This is for example an advertising panel comprising a block (or mechanism) loading MA in which is stored (for example by stacking) a set of advertising posters Ai. For example, the loading block MA comprises three posters A1 to A3 (i = 1 to 3) that it is responsible for displaying (or presenting) on a visible window of the public through a mechanism, individually, or by pair (see even by triplet), according to a command adapted for this purpose.

It should be noted that the invention is not limited to this type of display medium. It concerns indeed any type of fixed display support, capable of displaying on command information or information, including scrolling displays or display screens LED or plasma, for example. The (digital) display screens make it possible to avoid all the mechanics of storage and display. In addition, they may optionally transmit the data defining the information to be displayed with the display command. The display medium SA is associated with a first zone Z1. The latter is located in its vicinity (for example it surrounds it at least partially) and people and / or individual vehicles or public transport VT can move while viewing the information displayed by the display medium HER. The geographical position of this first zone Z1 is known.

The locating means ML1 and ML2 (or ML3 and ML4) are responsible for determining the presence of target persons in at least the first known geographical position area. By "target person" is meant here a person to whom a profile defined by one or more objective and / or subjective characteristics has been associated. Among the objective characteristics that can be used, mention may in particular be made of the number of past passes in front of the display medium SA concerned, the number of visualizations of each of the advertising posters, and the like. Among the subjective characteristics that can be used, mention may be made of gender, age, socio-professional category, occupation, professional and / or personal and similar areas of interest. In general, any type of criterion (or characteristic) can be used to define a profile. It should be noted that the profiles can be advantageously defined from the profiles used by the communication network operators to target their customers.

The first memory MS1 is responsible for storing the profiles of the target persons.

The calculation module MCL is responsible for distributing in selected groups the target persons whose presence has been determined in the first zone Z1 by the locating means ML1 and ML2 (or ML3 and ML4). By "group" is meant here a set defined by at least one profile characteristic. Note that different groups are defined by combinations of different characteristics. Moreover, it will be noted that a group can be defined by all the characteristics of a profile, or even of several profiles.

As illustrated, the management system may optionally comprise a definition module MD responsible for defining the aforementioned groups from the profiles stored in the first memory MS1, and to provide the definitions of these groups to the calculation module MCL.

The correspondence module MCR is responsible for establishing matches between the groups (linked to the profiles that are stored in the first memory MS1) and the information that must be displayed by the display medium SA. In other words, in the example described, the correspondence module MCR stores a correspondence table between the groups and the corresponding advertising posters respectively. The control module MCM is responsible for causing the display device SA to display at least one piece of information that corresponds to the characteristic (s) of a group that is chosen at least according to the number target groups that it groups compared to those grouped by other groups. This selected group includes at least two target individuals. If after a first attempt, a selected group includes only one target person, then we take the next group that includes at least two target people.

For example, and not limitation, the MCM control module may cause the display medium to display at least one item of information corresponding to the characteristic (s) of the group that groups the largest number of target persons. . In other words, when the control module MCM receives from the calculation module MCL the distribution on the different groups (linked by the correspondence table to the various posters Ai available) of the target persons who are considered as present in the first zone Z1 , it selects the group that is associated with the largest percentage and generates a display command to the relevant display medium SA so that it proceeds to display the poster Ai corresponding to that group selected in the correspondence table (MS 1).

It is recalled that in the presence of digital display screens, it is conceivable that the display control includes the data defining the information to be displayed or simply a descriptor (or identifier) of the information to be displayed ( to avoid network overload during transmission). This descriptor is converted by the processor MR, which includes the display medium SA (and which is responsible for translating the received display command into instruction (s) understandable (s) by the display mechanism MA), in data information to be displayed, for example by means of a correspondence table between different descriptors and information (advertising) to be displayed.

In the nonlimiting example illustrated in FIG. 1, the control module MCM, the first memory MS1 and the correspondence module MCR, as well as the possible group definition module MD are implemented. in an SS service server. Moreover, in the nonlimiting example illustrated in FIG. 1, the calculation module MCL and part of the locating means ML2 are located in a calculation server SC. A complementary part of the locating means ML1 is distributed in mobile communication equipment Tj carried by at least some of the target persons.

More specifically, in the nonlimiting example illustrated in FIG. 1, at least some of the target persons are equipped with a mobile communication terminal Tj (here j = 1 to 3) in which a satellite positioning module is located. ML1. For example, the mobile communication terminals Tj are mobile phones that are connected to an RM mobile (or cellular) communication network. The latter is for example a GSM / GPRS network ("Global System for Mobile Communications / General Packet Radio Service" in English) whose cells are managed by base stations (called BTS (for "Base Transceiver Station" in English)) . Of course, the cellular communication network can be of any other type since it allows the establishment of communications by waves (radio and / or hertzian - terrestrial and / or satellite). Therefore, it may be a UMTS network ("Universal Mobile Telecommunications Service" in English) whose base stations are called Nodes B, or a wireless LAN type WiFi or WiMAX, for example .

It will be noted that the calculation server SC preferably belongs to the operator of the mobile network RM. It is recalled that a satellite positioning module ML1 is responsible for delivering position measurement estimates of the equipment in which it is implanted, based on signals transmitted by a constellation of positioning satellites of a positioning network. type RNSS (for "Radio Navigation Satellite Service" in English), or GNSS, such as the GPS network, or the GLONASS network, or the future GALILEO network. It should be noted that the accuracy of the position measurements can be enhanced when the constellation of positioning satellites is coupled to a so-called "augmentation" system, of the SBAS type (for "Satellite" Based Augmentation System ", for example the EGNOS system.

Each satellite positioning module ML1 transmits the positioning data that it determines to a server of the network that is

5 to store them in a customer information database of the operator of the mobile communication network RM. This database can be the HLR (Home Location Register) if the subscriber is connected to the radio access network of his home network or the VLR

("Visitor Location Register" in English) if the subscriber is connected to the network of radio access of another operator than his own.

In the nonlimiting example illustrated in FIG. 1, the calculation server SC furthermore comprises a memory MS2 in which the definition of the first zone Z1 is stored, and more precisely the geographical positions of the characteristic points which belong to its perimeter. .5 This definition comes from the SS service server, which also stores it, for example in the first memory MS1 (or in any other memory).

As indicated above, this first zone Z1 is determined so as to cover a part of the territory surrounding a display medium SA and in which target persons can circulate, or possibly inside a VT vehicle, while being able to observe the poster Ai that is displayed. The definition of this first zone Z1 can be modified in time by the manager of the service server SS, in order to cover a more or less extensive territory, or to cover a larger or smaller population, especially in view of the time of day (The population density around the panel is generally lower during the night, for example).

FIG. 2 diagrammatically shows, in a view from above, an example of a first zone Z1. Here, the first zone Z1 is composed of: o - a first part Z11 corresponding to a parcel of territory facing the display medium SA, substantially rectangular, with a large side R and a small side O2-O3 equal to the width the display medium SA (defined between the points 02 and 03; 01 denoting the center), and two lateral portions Z12 and Z13 formed of sectors of 45 °, radius R and respective centers O2 and 03.

Of course, other values can be considered for the angular sectors as long as they allow the target persons to view the poster Ai that is displayed. Moreover, other decompositions of the first zone Z1 can be envisaged.

In the nonlimiting example illustrated in FIG. 1, the positioning modules ML1, implanted in the mobile terminals Tj of the target persons, transmit their geographical positions to their mobile network RM. The ML2 part of the locating means, here implanted in the calculation server, is then arranged to access the HLR information database in order to determine all the clients whose geographical positions are substantially contained in those defining the first zone Z1 . To do this, the ML2 part compares the stored geographical positions (preferably only the target persons designated as such by the SS service server) to those that define the first zone Z1 (stored in the second memory MS2), and each time that it detects an "identity" corresponding to a target person, it records the identifier of the corresponding target person. In a variant, it can be envisaged that the identifiers of the target persons and the corresponding geographical positions are periodically stored in a memory MS3 of the calculation server SC. In this case, the ML2 part has only to make its comparison from the geographical positions stored in the memory MS3. Whenever the ML2 part has determined all the target persons present in a first zone Z1, preferably in a given time interval, it communicates their identifiers to the calculation module MCL. The latter can then divide into the groups, the definitions of which have been communicated to him by the service server SS and which are for example stored in the second memory MS2 with the definitions of the profiles, the target persons whose presence has been determined in the first zone Z1. Then, it transmits to the control module a message comprising the distribution of the target persons on the different groups. A nonlimiting example of determination of a distribution will be described below.

Over a period of time IT elapsed, the ML2 part of the location module has determined that 50 people were present in the first zone Z1, for example located in a business district. For example, it may be agreed between the SS service server manager and his / her advertiser clients to make a selection according to selected criteria, such as, first of all, sex and then the socio-professional category. Groups have therefore been formed from these criteria, and then transmitted to the calculation server SC (RM mobile network operator holder of personal information on these customers). An example of a breakdown into groups and subgroups is given in the following table.

It will be noted, as illustrated, that the calculation server SC may for example comprise an MT timing module responsible for making the MCL calculation module work according to a chosen period, rather than quasi-continuously.

When the MCM control module receives the distribution message, it chooses one of the groups object of the distribution (and comprising at least two target persons), then determines in the correspondence module MCR the poster Ai corresponding to this group chosen (of course taking into account the posters Ai available in the SA display medium considered) and generates a display command to this display medium SA so that it can proceed to display the poster Ai determined. In the case of the example described above, the control module MCM retains that the population most represented in the first zone Z1 is the female population of socio-professional category A. By accessing the correspondence table MS1, the The control module determines that the socio-professional category A corresponds, for example, to an advertising poster Ai of an advertiser relating to jewelery or high-end cosmetics.

It should be noted that the decision for the selection of the poster Ai can be acquired with one or more levels of criteria. In the previous case, we went down to two levels of precision {sex + socio-professional category}, but this example is not limiting.

In the example described with reference to FIG. 1, the display control is transmitted to the display medium SA via the mobile network RM. The display medium SA therefore comprises a processing module MR equipped not only with a display control message processing processor, but also means for receiving radio (or radio) signals.

It should also be noted that the presence detection may also relate to VT vehicle occupants, in particular those providing public transport. Indeed, it is possible to have predictive information on people who regularly use public transport means VT, such as buses, subways, trains or buses, whose routes are generally predetermined and submitted to fixed hours. For example, if people use a public transport vehicle every day at the same time on the same line. Therefore, for these target persons it is not necessary that they have a location means, such as an ML1 satellite positioning module. One can indeed predict their presence inside a public transport vehicle VT which must cross a first zone Z1 thanks to the predictive information of the public transport network (relating to the habits of the target persons and to the paths of the vehicles VT ).

By equipping VT public transport vehicles with a medium locating, such as for example a satellite positioning module ML1, the ML2 part of the locating means can also detect the presence of a public transport vehicle in the first zone Z1 when performing the comparison of geographical positions. This part ML2 must, however, include a prediction sub-module responsible for determining the target persons who are not equipped with a mobile terminal Tj but who are present in the first zone Z1 because they are presumed to be on board a vehicle. VT public transport whose presence has been detected in the zone, based on predictive information provided by the operators of the transport networks and for example stored in the memory MS2 or MS3.

In this case, the calculation module MCL is responsible for distributing in the groups defined by the manager of the service server SS the individually detected target persons (via their positioning modules ML1) as well as the target persons determined by the sub-module of prediction of the ML2 part.

Moreover, it can also be envisaged that at least some of the target persons have a mobile terminal Tj equipped with a measurement module responsible for measuring physical quantities relating to the movements of the target person it equips. For example, the measurement module is responsible for measuring the speed and / or the direction changes of the mobile terminal Tj that it equips, and for transmitting to the calculation module MCL (here implanted in the calculation server SC) the values measured quantities, via the RM mobile network. In this case, the calculation module MCL is responsible for determining the target persons who are present in the first zone Z1, taking into account the physical quantities transmitted by their mobile terminals Tj.

For example, the calculation module MCL determines from the physical quantities received which are the target persons who are present in the first zone Z1 and who are about to leave it, but also who are the target persons who are at the same time. outside the first zone Z1 and which are about to enter. It is then able to not retain for the distribution the target persons who are likely to quickly exit the first zone Z1, but to retain those that are likely to enter quickly.

To do this, the calculation module MCL can for example begin by pre-retaining the target persons who are located at a distance from the edge (or border) of the first zone Z1 which is less than a first chosen threshold S1. Other target persons are automatically selected. Then, it multiplies the SP speed of a pre-selected target person, which has been considered by the ML2 part of the location means as present in the first zone Z1, by a time of attention which can take two values: a first value V1 when this target person is likely to leave the first zone Z1 (taking into account the direction of its velocity vector), and a second value V2 when the target person is likely to enter the first zone Z1 (taking into account the the direction of its velocity vector). Finally, it compares to a second threshold S2 chosen the result of each multiplication (SPxVI or SPxV2) concerning a pre-selected target person, in order to retain only those that are associated with a result greater than the second threshold S2.

The first V1 and second V2 attention time values are chosen according to the level of attention a target person has towards a displayed information when it leaves the first zone Z1 or when there penetrates. This level being generally higher when entering the first zone Z1, V2 is preferably chosen to be greater than V1.

In a variant which corresponds to the situation illustrated in FIG. 3, a second zone Z2 may be associated with the display medium SA. More precisely, a second zone Z2 is defined around at least a portion of its first zone Z1, in order to take into consideration in the aforementioned processing only the target persons who are considered as present in the first zone Z1 or in the second zone Z1. zone Z2. For example, the first MS 1 and / or the second memory MS 2 can also store the geographic positions that define the perimeter of the second zone Z 2. In this case, the ML2 part of the locating means can determine the target persons who are present in the second zone Z2 by comparing their geographical positions stored (for example) in the HLR database at geographical positions defining the second zone Z2. The calculation module MCL can then determine among the target persons who are present in the second zone Z2 those who are likely to quickly enter the first zone Z1 given their respective physical magnitudes.

As indicated above, the control module MCM is responsible for causing the display medium to display at least one item of information corresponding to the characteristic (s) of one of the groups, chosen according to the number of target groups it groups compared to those of other groups. But, it can also make its choice based on minimum quota and / or maximum information that must be displayed over a given period.

Indeed, the final selection of the advertising poster to be selected can be made according to a minimum quota of posters that should be displayed over a given period (for example over a day) to avoid discriminating against certain advertisers who may to be poorly represented and / or to respect certain contractual commitments with them. These quotas are for example defined in a quota table stored in a memory of the SS service server.

Thus, to use the example presented in the previous table, if several successive determinations led to the selection of the same poster Ai (same result (female population of socio-professional category A}), then the control module MCM must check whether minimum / maximum quota have been defined. If this is the case, the control module MCM must select another group (for example that associated with the distribution the second largest) and generate a display command designating the poster Ai associated with this group in the correspondence table. MCR (if his personal quota has not already been reached).

FIG. 4 illustrates a non-limiting example of a daily information display quota table in the case of a display medium SA containing three posters A1, A2 and A3, respectively for three AV displays, A2 'and A3'. Each time a poster Ai of the display medium SA is displayed, its effective display time is counted from the maximum display time recorded in the quota table. When an Ai poster has been displayed for an effective duration greater than or equal to its maximum display time, it can no longer be displayed for the current period. By cons, when the given period (here the day) is expired, several situations can appear:

the manager of the service server SS can store new data in the quota table, it can be decided, in the absence of any outside intervention, to reset the display durations to their initial respective values,

- It may be decided to memorize new advertising information corresponding to new advertisers and reset the display times to their respective initial values for advertisers for whom the information has not been changed.

It will be noted that the processing module MR of the display medium SA may comprise means for transmitting / receiving data, preferably short-range, in order to broadcast at least in the first zone

Z1 the information to display. Thus, each mobile terminal Tj of a target person can, if it is equipped with means for receiving short-range data, receive the information that is broadcast by the neighboring SA display medium. This significantly increases the likelihood that the target person will observe the information displayed. The short-range transmission technology that is used can be of any type, including RFID, Bluetooth, WiFi or infrared for example.

Referring now to Figures 5 and 6 to describe a second embodiment of the system according to the invention.

This second embodiment takes up almost all the elements (modules) constituting the system described above, while changing the location of a portion of them.

More specifically, the invention proposes to implement at least the MCM control module in a management device D housed in a display medium SA (as shown in Figure 5) or connected to the latter. In this case, the control module MCM receives from a calculation module MCL the definitions of the distributions of the target persons considered as present in the first zone Z1 associated with its display medium SA and can implement the same functions as those described above with reference to Figures 1 to 4. It is thus at least responsible for causing the display medium to display at least one piece of information corresponding to the characteristic (s) of one of the groups target persons in which the target persons whose presence has been determined in its first Z1 zone have been distributed according to the number of target persons it groups compared with those of the other groups, as well as possibly according to the quota minimum and / or maximum information that must be displayed over a period of time. This selected group includes at least two target individuals.

The group definitions and the local correspondence table between the groups and the available posters Ai can for example be transmitted by the service server SS and stored by the management device D in a memory MS4 accessible to the control means MCM.

As illustrated in FIG. 6, the management device D may also comprise an MCL calculation module responsible for distributing in the groups the target persons whose presence has been determined individually (as well as possibly collectively thanks to the predictive information) in the first zone ZI by the locating means ML3 and ML4. In general, the calculation module MCL can implement the same functions as those described above with reference to FIGS. 1 to 4.

The management device D may also include a timer module MT responsible for making its possible calculation module MCL work according to a chosen period, as previously described. In this second embodiment, the SS service server can be simplified, since it no longer needs to understand centralized control module. It now contains the MCR correspondence module that stores the correspondence table between the group definitions and the posters Ai that can be displayed by each display medium SA of the management system, the optional definition module MD making it possible to define the groups from the profiles, and the first memory MS1 responsible for storing the profiles of the target persons. This second embodiment is particularly well suited, although not limitatively, to the case where the presence detection is carried out in each management device D for the first zone Z1 of its display medium SA.

Indeed, and as illustrated in FIG. 6, the management device D may comprise a part of the locating means ML4, the other part ML3 of these locating means equipping at least some of the target persons, for example inside of their mobile terminal Tj.

More specifically, the ML3 portion consists of data transmission modules, preferably short-range. Each ML3 data transmission module equips a target person and is responsible for transmitting radio signals that are representative of the identity of that target person. He could also transmit the profile associated with this identifier.

The management device D then comprises a data receiving module MER for capturing the radio signals emitted by the neighboring ML3 data transmission modules in order to communicate the data they comprise to the part ML4 of the location means.

The short-range transmission technology that is used can be of any type, including RFID, Bluetooth, WiFi or infrared for example. The ML4 portion of the locating means is therefore responsible for estimating the distance between the display medium SA, which it equips, with the target person whose data transmission module ML3 has sent a radio signal received by the MER reception module. Knowing the definition of the first zone Z1, it can then determine if the target person who transmitted the received radio signal is located in the first zone ZI. If this is the case, the ML4 portion stores the identifier of the target person that is defined by the data of the received radio signal. It can then communicate this identifier to the calculation module MCL of its device D so that it takes it into account in its distribution. This therefore requires the MCL calculation module to have access to the memory where the identifiers of the target persons are stored in correspondence of their respective profiles. As illustrated in FIG. 6, the device D may comprise an memory MS5 intended to store the identifiers of the target persons in correspondence of their respective profiles. This memory MS5 is for example supplied with data by the operator of the mobile network RM, or by the service server SS. But, as a variant, it is conceivable for the calculation module MCL to provide the mobile network RM with the identifiers of the detected target persons so that it transmits back to it the definitions of the profiles which are respectively associated with these identifiers.

If each party ML3 transmits an associated identifier and profile, the MCL calculation module no longer needs to have access to the memory where the identifiers of the target persons are stored in correspondence of their respective profiles.

Note that in this second embodiment, it is not useful for the management system to include a calculation server SC. But, we can consider a variant in which this can be useful. Indeed, in order to avoid the transfer of partially confidential data between the mobile network RM and the management devices D, it can be envisaged that the latter do not comprise a calculation module MCL of decentralized type, but that a calculation module centralized is provided in the calculation server SC, as described above with reference to Figures 1 to 4.

In this case, each device D must transmit to the calculation server SC the identifiers of the detected target persons so that it proceeds with the distribution and addresses this distribution to its MCM control module.

It can also be envisaged that the management devices D do not comprise a detection module ML4 of decentralized type, but that a centralized part ML2 of the locating means is provided in the calculation server SC, as described previously with reference to the figures

1 to 4. In this case, the mobile terminals Tj of the target persons must be equipped with a satellite positioning module ML1 (as previously described with reference to FIGS. 1 to 4) and no longer with a module ML3 data transmission at short range.

Note that in this second embodiment, as in the first embodiment, the transmission / reception module MER of the management device D can be arranged to broadcast at least in the first zone Z1 the information to be displayed. Thus, each mobile terminal Tj of a target person can, if it is equipped with means for receiving short-range data, receive the information that is broadcast by the neighboring SA display medium. This significantly increases the likelihood that the target person will observe the information displayed. Moreover, at least in the case of the first embodiment, it is conceivable that one of the display media SA of the management system is responsible for receiving for it and for other display media messages containing the display commands (as well as any definitions or descriptors of the information to be displayed) from the SS service server, and that it be responsible for broadcasting them by radio waves).

In a variant, it is possible to envisage a mode of transmission (propagation) step by step of the messages containing the display commands (as well as any definitions or descriptors of the information to be displayed) coming from the service server SS. In one case as in the other, the transmission and reception can for example be done on a given band (for example VHF), the transmission being further TDMA mode synchronized to the GPS pulse, for example. The reception can be done continuously, each message then containing the references of the display medium ensuring the relay and the data broadcast.

This mode of operation can also be used to modify the information stored in the SA display media or the correspondence between descriptors and information, in particular when they comprise a digital display screen. This information may for example be provided by means of a short-range transmission technique by a technical agent who travels in a vehicle equipped with a discount station.

All or part of the different modules constituting the device of D management, the service server and the calculation server, according to the invention, can be made in the form of electronic circuits, software modules (or computer), or a combination of circuits and software.

It will also be noted, as is schematically illustrated in FIG. 7, that the service server SS can be connected (or coupled, for example via the mobile communication network RM) to devices EA1 ', EA2', EA3 'd. 'AV, A2', A3 '(Ak') advertisers responsible for defining, for each advertiser, data of any type comprising information to be displayed, profiles of targeted target persons and sets of relevance criteria (as presented hereinafter according to one embodiment). In this case, the equipment EA1 ', EA2', EA3 'feeds the definition module MD, by own reception inputs not shown, to characterize the aforementioned groups. The definition module MD then provides the definitions of these groups to the calculation module MCL. Such an SS service server may in particular belong to an advertising agency or an advertising broker managing advertising space.

AT LEAST PARTIALLY MOBILE DISPLAY MEDIUM (S) The term "display medium" (or "movable support") is now used to mean a material comprising a mobile display part, or movable because it is mounted on a vehicle, possibly of public transport, and intended to support a poster, possibly of an advertising nature, or to display information (or information), possibly of an advertising nature, for a given period of time so that it (s) can ) be observed by an audience in its vicinity.

Mobile advertising is traditionally carried by at least partially mobile media such as billboards (possibly scrolling) or display screens for example light-emitting diodes (LED) or plasma) rotatably mounted on a base or mounted on vehicles using, preferably, very busy routes (city boulevards, major highways, airport or train stations, for example). These ads may have been affixed by gluing on the "mobile" support. There are also mobile media with several posters scrolling in turn, or selectable in a "tank" and displayed on the visible side of the mobile support for a predetermined time. The invention relates to mobile supports for selecting one of several displays or displaying on a screen information, information, an image or a video clip.

Display companies (so-called billboards) have at their disposal fixed and / or mobile display networks and offer their advertising customers qualified displays according to the target sought. The rating of the display networks is a standard parameter for advertisers and viewers through a particular nomenclature that generally divides the population into five social level layers (A, B, C, D, E): thus, if the advertiser is interested in targeting a cadre population, it will require category "B" targeting; a senior management population will correspond to category "A" targeting, etc. For example, a Category A signage network is often located in a large city, near business offices or residential neighborhoods.

However, the qualification of the display networks remains limited to the predefined categories and there is no other technical means of targeting the audience. At most, some advertisers can have surveys done on the spot, that is to say close to the areas in which the mobile advertising supports are moved, to know the profile of the individuals passing by and the impact that has left this advertisement in their minds. This single way of measuring targeting is very little used because it is expensive and provides the opinion of only a very limited panel of people (very) unrepresentative of the entire population. In addition, it does not respond quickly, given the time required to obtain and analyze the results of opinion surveys. The object of the present invention is therefore to solve the problem set out above in order to provide a more precise targeting that is as much as possible in affinity with the passing public.

For this purpose, the invention proposes a system for managing the display information on at least one mobile display medium at least partially along a path, further comprising:

locating means for determining target persons, associated with profiles defined by objective characteristics and / or

5 subjective, likely to be present in a given time interval in at least a first zone (known perimeter, attached to a portion of the display medium that follows the path, located in the vicinity of the latter, and in which it is in visibility of the target persons), taking into account the trajectory followed, o - first storage means responsible for storing the profiles of the target persons,

calculating means designed to distribute in groups, which are each defined by at least one profile characteristic, the determined target persons who are likely to be present in the first zone in the time interval,

control means responsible for causing the display medium to display at least one item of information corresponding to the characteristic (s) of one of the groups chosen as a function of the number of target persons it groups compared to those of the other groups, the selected group comprising at least two target persons.

The invention thus has a dual function, the first is that of analyzing the average profile of the public attending an area located near a "mobile" display medium (for example, if the public has been previously qualified "AB The invention makes it possible to verify it, and even to refine the qualification), and the second is that of the targeting of the public according to the result of the analysis obtained, in order to provide to the public information corresponding to a part of the less than his average profile. o In this way, the invention achieves the goal desired by any advertiser, namely the targeting of the public by micro-segmentation and the display of really useful information, thus ensuring the optimization of the budget of advertisers. The invention being based on the concept of groups, it makes it possible to provide a technical solution to the dual technical problem of prohibiting the use of personal data of target persons (such as users) and the technical unavailability, for certain actors of the economic circuit, of this personal data in their databases. Indeed, because of the prohibition or refusal to commercially exploit this personal data, customer files can not be transmitted to economic partners, for example mobile operators can not transmit such files to customers. service providers. Due to the obstacle created by this unavailability, the targeting of the advertising data was in the reduced prior art.

The system according to the invention can comprise other characteristics that can be taken separately or in combination, and in particular: the display medium can for example comprise a part dedicated to the information display and rotatably mounted on a base so as to follow a circular path according to a chosen rotational speed; as a variant, the display support can be mounted on a vehicle capable of to be in motion along a certain path. In this case, the location means are responsible for determining the geographical position and the speed of the vehicle and the presence in the given time interval of target persons in at least the first area taking into account the geographical position and speed of the vehicle;

its control means may be responsible for causing the display medium to display at least one piece of information corresponding to the characteristic (s) of one of the groups chosen according to the number of target persons that it groups compared to those of the other groups and according to minimum quota and / or maximum of information to be displayed over a given period;

said groups are defined by characterization means capable of defining groups of target persons, each defined by at least one objective and / or subjective profile characteristic, in that the characterization means comprise means for defining sets of targets. relevance criteria including at least one profile characteristic, a minimum number of target persons to be reached, and a maximum budget for a display, each set of relevance criteria being associated with information to be displayed and being provided by an advertiser, in that that the computing means are arranged to distribute in said groups the target persons whose presence has been determined according to said sets of profile characteristics defined by said advertisers, in that the system comprises selection means for selecting among said groups for which the minimum number of target persons is reached, and the control means are arranged to cause the display of the information that is associated with the selected group for which the advertiser has defined the highest of the maximum budgets;

alternatively or in addition, its location means may comprise i) short-range data transmission means equipping at least some of the target persons and each responsible for transmitting signals representative of the identity of the target person that it equips, and ii) charged detection means, in the event of reception of signals emitted by a transmission means, of estimating the distance separating the display medium from the target person who is equipped with this means of transmission. emission, and thus to determine if this target person is located in the first zone in the given time interval, taking into account the trajectory followed;

- The display medium may comprise means for transmitting / receiving short-range data responsible for broadcasting at least in the first zone the information to be displayed. In this case, each terminal of mobile communication (equipping a target person) comprises means for receiving short-range data for receiving the information broadcast by the display medium;

it may comprise second storage means responsible for storing the definition of the perimeter of the first zone;

it may comprise third storage means responsible for storing the geographical positions of the target persons;

its locating means may be responsible for detecting the presence of a public transport vehicle in the first zone. In this case, it may comprise prediction means responsible for determining, as a function of predictive information, target persons, different from those individually detected and who are embedded in a public transport vehicle likely to be present in the first zone in the first zone. the time interval. Its calculation means are then responsible for distributing in the groups the individually detected target persons as well as the target persons determined by the prediction means;

it may comprise measuring means for measuring physical quantities relating to the movements of a target person and selected from a group comprising at least speed and changes of direction. In this case, its calculating means may be responsible for determining the target persons who are likely to be present in the first zone in the given time interval, taking into account the trajectory followed and the physical quantities measured by the means of communication. measured. Target persons likely to exit quickly from the first zone are not retained while target persons likely to enter the first zone quickly are retained; its calculation means can be loaded i) to pre-retain the target persons who are located at a distance from the predicted position of the edge of the first zone below a first chosen threshold, then ii) to multiply the speed of a pre-selected target person by a time attention that can take either a first value when the target person is likely to leave the first zone, a second value when the target person is likely to enter the first zone, and iii) compare to a second threshold chosen the result of each multiplication concerning a pre-selected target person, in order to retain only the pre-selected target persons associated with a result greater than the second threshold;

the second storage means may be responsible for storing the definition of the perimeter of at least one second zone surrounding the first zone and attached thereto. In this case, the locating means may be responsible for determining the target persons who are likely to be present in the second zone in the given time interval, taking account of the trajectory, and the calculation means can be loaded with to retain the target persons who are likely to be present in the second zone and who are likely to enter the first zone rapidly, taking into account the physical magnitudes measured by their respective measuring means and trajectory;

its first storage means can be supplied with profile data of a customer information database of an operator of a mobile communication network;

each display medium may comprise a poster loading block, a mechanism for selecting one of the posters to be loaded and the part that is responsible for displaying a selected poster so that it is visible to at least the persons targets that are located in the first zone;

the vehicle may for example comprise at least two distinct faces on which are mounted two display supports attached to first distinct zones which follow the path of the vehicle. In this case, the locating means are responsible for determining the presence in the given time interval of target persons in each of the first zones, and the computing means are responsible for distributing in a first set of groups the target persons whose presence has been determined in one of the first two zones, and in a second set of groups the target persons whose presence has been determined in the other of the first two zones. In addition, the control means are responsible for causing each of the two display media to display at least one piece of information corresponding to the characteristic (s) of one of the groups of the corresponding set chosen. according to the number of target persons it groups compared to those of the other groups of the same group, the selected group comprising at least two target persons.

Reference is first made to FIG. 1 to present an information display management system according to a first embodiment of FIG. the invention.

As illustrated in FIG. 1a, a management system according to the invention comprises at least one display medium SA, at least partially mobile, means for locating target persons ML1-ML3, a first memory MS1, an MCR correspondence module, an MCL calculation module and an MCM control module.

In what follows we consider only the case of a management system comprising a single display medium SA, to simplify the description of the invention. However, the invention applies to any management system comprising at least a "mobile" display medium SA.

Furthermore, in what follows, by way of illustrative and non-limiting example, the information to be displayed is of an advertising nature.

But, the invention is not limited to this type of information. It also concerns the display of information relevant to a given population. The display support SA can be mounted on a vehicle VT

(As shown in Figure 1a), and in this case its mobility is governed by that of the vehicle VT, is fixed by means of a base (or base) BF at a chosen location, for example on a square, and only its AF display can be rotated relative to its base BF (as shown in Figure 2a), and in this case its mobility is governed by that of its AF display.

In the following, by way of illustrative and nonlimiting example, the display medium SA is mounted on the body of a vehicle VT, for example public transport.

The display medium SA is for example an advertising panel comprising a block (or mechanism) loading MA in which is stored (for example by stacking) a set of advertising posters Ai. For example, the loading block MA comprises three posters A1 to A3 (i = 1 to 3) that it is responsible for displaying (or presenting) on a visible window of the public through a mechanism, individually, or by pair (see even by triplet), according to a command adapted for this purpose.

It should be noted that the invention is not limited to this type of display medium SA. It concerns indeed any type of display medium that can be mounted on a vehicle VT or having a rotary display AF, capable of displaying on command information or information, including scrolling displays or display screens LED or plasma, for example. The (digital) display screens make it possible to avoid all the mechanics of storage and display. In addition, they may optionally transmit the data defining the information to be displayed with the display command.

The display medium SA is associated with a first zone Z1. The latter is located in its vicinity (for example it surrounds it at least partially) and people and / or individual vehicles or public transport VT can move while viewing the information displayed by the display medium HER. The perimeter of this first zone Z1 is known. Furthermore, this first zone Z1 is attached to a part of the display medium which follows the path TR (that is to say to all the display medium SA in the case of FIG. 1a and to the display rotary AF in the case of Figure 2a).

A schematic example of trajectory TR of a vehicle VT on a road (or road) RC is illustrated in Figure 3a. The arrows FO materialize the velocity vector at the instant considered vehicle VT (and therefore the first zone Z1 attached to its display medium SA).

The locating means ML1 and ML2 (or ML3 and ML4) are responsible for determining target persons who are likely to be present in a given time interval in at least the first area taking into account the track TR followed. By "target person" is meant here a person to whom a profile defined by one or more objective and / or subjective characteristics has been associated. Among the objective characteristics that can be used, mention may in particular be made of the number of past passes in front of the display medium SA concerned, the number of visualizations of each of the advertising posters, and the like. Among the subjective characteristics that can be used, mention may be made of gender, age, socio-professional category, occupation, professional and / or personal and similar areas of interest. In general, any type of criterion (or characteristic) relating to the target person can be used to define a profile. It should be noted that the profiles can be advantageously defined from the profiles used by the communication network operators to target their customers.

Here, the term "time interval", a time separating two successive positions of a display medium SA (or its rotary display AF) P (ti) and P (ti + 1), as illustrated in FIG. 4a . At the instant ti, which corresponds to the position P (ti) of the vehicle VT (and therefore of the first zone Z1), the locating means ML1 and ML2 (or ML3 and ML4) determine the positions of the target persons. The instant ti + 1 is used by the locating means ML1 and ML2 (or ML3 and ML4) to predict the location P (ti + 1) where the vehicle VT (and thus the first zone Z1) will be located taking into account its position P (ti) and its vector velocity at time ti. It is therefore at the predicted position P (ti + 1) of the first zone Z1 that one must determine if target persons are present at time ti. It is considered here that the speed of movement of the display medium SA (or its rotary display AF) is significantly faster than that of a pedestrian.

The calculation module MCL is responsible for distributing in selected groups the target persons that have been determined by the locating means ML1 and ML2 (or ML3 and ML4) and which are therefore likely to be present in the first zone in the time interval. By "group" is meant here a set defined by at least one profile characteristic. Note that different groups are defined by combinations of different characteristics. Moreover, it will be noted that a group can be defined by all the characteristics of a profile, or even of several profiles. As illustrated, the management system may optionally comprise a definition module MD responsible for defining the aforementioned groups from the profiles stored in the first memory MS1, and to provide the definitions of these groups to the calculation module MCL. The correspondence module MCR is responsible for establishing matches between the groups (linked to the profiles that are stored in the first memory MS1) and the information that must be displayed by the display medium SA. In other words, in the example described, the correspondence module MCR stores a correspondence table between the groups and the corresponding advertising posters respectively.

The control module MCM is responsible for causing the display device SA to display at least one piece of information that corresponds to the characteristic (s) of a group that is chosen at least according to the number target groups that it groups compared to those grouped by other groups. This selected group includes at least two target individuals. If after a first attempt, a selected group includes only one target person, then we take the next group that includes at least two target people. For example, and not limitation, the MCM control module may cause the display medium to display at least one item of information corresponding to the characteristic (s) of the group that groups the largest number of target persons. . In other words, when the control module MCM receives from the calculation module MCL the distribution on the different groups (linked by the correspondence table to the various posters Ai available) of the target persons who are considered as present in the first zone Z1 , it selects the group that is associated with the largest percentage and generates a display command to the relevant display medium SA so that it proceeds to display the poster Ai corresponding to that group selected in the correspondence table (MS1).

It is recalled that in the presence of digital display screens, it is conceivable that the display control includes the data defining the information to be displayed or simply a descriptor (or identifier) of the information to be displayed ( to avoid network overload during transmission). This descriptor is converted by the processor MR, which includes the display medium SA (and which is responsible for translating the display command received into instruction (s) understandable (s) by the display mechanism MA), in information data to be displayed, for example by means of a correspondence table between different descriptors and information (advertising) to be displayed.

In the nonlimiting example illustrated in FIG. 1a, the MCM control module, the first memory MS1 and the correspondence module MCR, as well as the eventual group definition module MD are located in an SS service server. Moreover, in the nonlimiting example illustrated in FIG. 1a, the calculation module MCL and part of the locating means ML2 are located in a calculation server SC. A complementary parto of the locating means ML1 is distributed in mobile communication equipment Tj carried by at least some of the target persons and in the vehicle VT which carries the display medium SA. Note that in the case of a rotary display AF rotation law can be known in advance, so that we can know at any time its orientation with respect to a reference direction. It is then useless to equip the display medium SA with locating means ML1. This may nevertheless be useful when the detection is done locally (as will be seen later with reference to FIGS. 8a and 9a).

More precisely, in the nonlimiting example illustrated in FIG. 1a, where the vehicle VT and at least some of the target persons are equipped with a mobile communication terminal Tj (here j = 1 to 4) in which an implanted ML1 satellite positioning module. For example, the mobile communication terminals Tj are mobile phones that are connected to an RM mobile (or cellular) communication network. This last is for example a GSM / GPRS network ("Global System for Mobile Communications / General Packet Radio Service" in English) whose cells are managed by base stations (called BTS (for "Base Transceiver Station")) . Of course, the cellular communication network can be of any other type as it allows the establishment of communications by waves (radio and / or radio - terrestrial and / or satellite). Therefore, it may be a UMTS network ("Universal Mobile Telecommunications Service" in English) whose base stations are called Nodes B, or a wireless LAN. WiFi or WiMAX, for example.

It will be noted that the calculation server SC preferably belongs to the operator of the mobile network RM.

It is recalled that a satellite positioning module ML1 is responsible for delivering position measurement estimates of the equipment in which it is implanted, based on signals transmitted by a constellation of positioning satellites of a positioning network. type RNSS (for "Radio Navigation Satellite Service" in English), or GNSS, such as the GPS network, or the GLONASS network, or the future GALILEO network. It will be noted that the accuracy of the position measurements can be enhanced when the constellation of positioning satellites is coupled to a so-called "augmentation" system, of the SBAS (for Satellite Based Augmentation System) type, such as the EGNOS system. Each satellite positioning module ML1 transmits the positioning data that it determines to a server of the network which is responsible for storing them in a customer information database of the operator of the mobile communication network RM. This database can be the HLR (Home Location Register) if the subscriber is connected to the radio access network of his home network or the VLR (Visitor Location Register) if the subscriber is connected to the radio access network of another operator than his own.

In the nonlimiting example illustrated in FIG. 1a, the calculation server SC furthermore comprises a memory MS2 in which the definition of the perimeter of the first zone Z1 is stored. This definition comes from the SS service server, which also stores it, for example in the first memory MS1 (or in any other memory).

As indicated above, this first zone Z1 is determined so as to cover part of the space surrounding a display medium SA and in which target persons can circulate, possibly inside a VT vehicle, while can observe the poster Ai that is displayed. The definition of this first zone Z1 can be modified in time by the manager of the service server SS, in order to cover a larger or smaller area, or cover a larger or smaller population, especially in view of the time of day (for example, the population density around the sign is lower during the night). FIG. 5a shows, diagrammatically, in a view from above, an example of a first zone Z1. Here, the first zone Z1 is composed of:

a first part Z11 corresponding to a parcel of territory facing the display medium SA, substantially rectangular, with a large side R and a small side O2-O3 equal to the width of the display medium SA (defined between the points 02 and 03; 01 designating the center), and

two lateral portions Z12 and Z13 formed of sectors of 45 °, radius R and respective centers 02 and 03.

In the nonlimiting example illustrated in FIG. 1a, the positioning modules ML1, located in the mobile terminals Tj of the target persons and of the vehicle VT, transmit their geographical positions to their mobile network RM. The ML2 part of the locating means, here implanted in the calculation server SC, is then arranged to access the HLR information database in order to determine the geographical position P (ti) and at least the prior geographical position P ( ti-1), and deduce from these successive geographical positions the speed of the vehicle VT. It can also be envisaged that the vehicle VT transmits its speed directly at the same time as its position. Then, the ML2 part predicts the following position P (ti + 1) of the vehicle VH, and therefore of the first zone Z1 from the geographical position P (ti) and the associated speed. The ML2 part then accesses the HLR information database again to determine all the clients whose geographical positions are substantially contained in those defining the first zone Z1 for the predicted position P (ti + 1). To do this, the ML2 part compares the stored geographic positions (preferably only the target persons designated as such by the SS service server) to those defining the first zone Z1 given the definition of its perimeter stored in the second memory MS2, and each time 5 that it detects an "identity" corresponding to a target person, it records the identifier of the corresponding target person.

In a variant, it is possible to envisage that the identifiers of the target persons and the corresponding geographical positions are periodically stored in a memory MS3 of the calculation server SC.o In this case, the part ML2 has only to carry out its comparison from geographical positions stored in the memory MS3.

Whenever the ML2 part has determined all the target persons present in a first zone Z1, preferably in a given time interval, it communicates their identifiers to the calculation module MCL. The latter can then divide into the groups, the definitions of which have been communicated to him by the service server SS and which are for example stored in the second memory MS2 with the definitions of the profiles, the target persons who are likely to be in the group. first zone Z1 in its predicted position P (ti + 1). Then, it sends the commando MCM module a message with the distribution of the target persons on the different groups.

A nonlimiting example of determination of a distribution will be described below.

Over an elapsed time interval IT, the ML2 part of the location module has determined that 50 persons are likely to be present in the first zone Z1 in its predicted position P (ti + 1), for example located in a neighborhood of business. For example, it may be agreed between the SS service server manager and his advertiser clients to make a selection according to selected criteria, such as first sex and then socio-professional category. Groups have therefore been formed from these criteria, and then transmitted to the calculation server SC (RM mobile network operator holder of personal information on these customers). An example of division into groups and subgroups is given in the following table.

When the MCM control module receives the distribution message, it chooses one of the groups object of the distribution (and comprising at least two target persons), then determines in the correspondence module MCR the poster Ai corresponding to this group chosen (of course taking into account the posters Ai available in the SA display medium considered) and generates a display command to this display medium SA so that it can proceed to display the poster Ai determined. In the case of the example described above, the control module

MCM holds that the population most represented in the first zone Z1 is the female population of socio-professional category A. By accessing the correspondence table MS1, the control module determines that the socio-professional category A corresponds, for example, to an advertising poster Ai of an advertiser relating to jewelery or high-end cosmetics.

In the example described with reference to FIG. 1a, the command display is transmitted to the display medium SA via the mobile network RM. The display medium SA therefore comprises a processing module MR equipped not only with a display control message processing processor, but also means for receiving radio (or radio) signals.

Note also that the presence detection may also relate to occupants of vehicles VH, especially those providing public transport. Indeed, it is possible to have predictive information on people who regularly use public transport means VH, such as buses, subways, trains or buses, whose routes are generally predetermined and submitted to fixed hours. For example, if people use a public transport vehicle every day at the same time on the same line. Therefore, for these target persons it is not necessary that they have a location means, such as an ML1 satellite positioning module. We can indeed predict their presence inside a public transport vehicle VH that must cross a first zone Z1 thanks to the predictive information of the public transport network (relating to the habits of the target persons and to the VH vehicle journeys ).

By equipping VH public transport vehicles with a locating means, such as for example a satellite positioning module ML1, the part ML2 of the locating means can also detect the presence of a public transport vehicle in the first Z1 area when comparing geographical positions. This part ML2 must, however, include a prediction sub-module responsible for determining the target persons who are not equipped with a mobile terminal Tj but who are likely to be present in the first zone Z1 in its predicted position P (ti + 1) because they are presumed to be loaded onto a public transport vehicle VH which is likely to be present in the first zone Z1 in its predicted position P (ti + 1), on the basis of predictive information provided by the operators of the transport networks and for example stored in the memory MS2 or MS3. In this case, the calculation module MCL is responsible for distributing in the groups defined by the manager of the service server SS the individually detected target persons (via their positioning modules ML1) as well as the target persons determined by the sub-module of prediction of the ML2 part.

Moreover, it can also be envisaged that at least some of the target persons have a mobile terminal Tj equipped with a measurement module responsible for measuring physical quantities relating to the movements of the target person it equips. For example, the measurement module is responsible for measuring the speed and / or the direction changes of the mobile terminal Tj that it equips, and for transmitting to the calculation module MCL (here implanted in the calculation server SC) the values measured quantities, via the RM mobile network.

In this case, the calculation module MCL is responsible for determining the target persons who are likely to be present in the first zone Z1 in its predicted position P (ti + 1) taking into account the physical quantities transmitted by their mobile terminals Tj .

For example, the calculation module MCL determines from the physical quantities received which are the target persons who are likely to be present in the first zone Z1 in its predicted position P (ti + 1) and which are about to to leave, but also which target persons are outside the first zone Z1 in its predicted position P (ti + 1) and are about to enter it. He is then able to not retain for the distribution the target persons who are likely to exit quickly from the first zone Z1 in its predicted position P (ti + 1), but to retain those who are likely to enter quickly.

To do this, the calculation module MCL can for example start by pre-retaining the target persons who are located at a distance from the predicted position of the edge (or border) of the first zone Z1 (in its predicted position P (ti + 1)) which is less than a first selected threshold S1. Other target persons are automatically selected. Then, it multiplies the SP speed of a pre-selected target person, which has been considered by ML2 locating means as likely to be present in the first zone Z1, by an attention time which can take two values: a first value V1 when this target person is likely to leave the first zone Z1 in its predicted position P ( ti + 1) (taking into account the direction of its velocity vector), and a second value V2 when the target person is likely to enter the first zone Z1 in its predicted position P (ti + 1) (taking into account the direction of its velocity vector). Finally, it compares to a second threshold S2 chosen the result of each multiplication (SPxVI or SPxV2) concerning a pre-selected target person, in order to retain only those that are associated with a result greater than the second threshold S2.

The first V1 and second V2 attention time values are chosen according to the level of attention a target person has towards a displayed information when leaving the first zone Z1 (in its predicted position P (ti + 1)) or when it enters. This level being generally higher when entering the first zone Z1, V2 is preferably chosen to be greater than V1.

In a variant which corresponds to the situation illustrated in FIG. 6a, a second zone Z2 can be connected to the display support SA. More precisely, a second zone Z2 is defined around at least a portion of its first zone Z1, in order to take into consideration in the aforementioned processing only the target persons who are considered likely to be present in the first zone Z1. or in the second zone Z2. For example, the first MS 1 and / or the second memory MS 2 can also store the definition of the perimeter of the second zone Z 2. In this case, the ML2 part of the locating means can determine the target persons who are likely to be present in the second zone Z2 as it does for the first zone Z1 in its predicted position P (ti + 1).

The ML2 part of the locating means, here implanted in the calculation server SC, predicts the position P '(ti + 1) occupied by the set of the second zone Z2 taking into account the definition of its perimeter (which is stored in the second memory MS2) and its predicted position P (ti + 1) of the first zone Z1. ML2 then accesses the HLR information database to determine all customers whose positions are substantially contained in those defining the second zone Z2 for the predicted position P '(ti + 1). To do this, the ML2 part compares the stored geographic positions (preferably only target persons designated as such by the SS service server) to those that define the second zone Z2 given the definition of its perimeter, and whenever it detects an "identity" corresponding to a target person, it records the identifier of the corresponding target person.

The calculation module MCL can then determine among the target persons who are likely to be present in the second zone Z2 in its predicted position P '(ti + 1) those who are likely to quickly enter the first zone Z1 in its predicted position P (ti + 1) given their respective physical magnitudes.

As indicated previously, the control module MCM is responsible for causing the display medium SA to display at least one piece of information corresponding to the characteristic (s) of one of the groups, chosen according to the number target groups that it groups compared to those of the other groups (this selected group comprising at least two target persons). But, it can also make its choice based on minimum quota and / or maximum information that must be displayed over a given period.

Thus, to use the example presented in the previous table, if several successive determinations led to the selection of the same poster Ai (same result (female population of socio-professional category A}), then the control module MCM must check whether minimum / maximum quota have been defined. If this is the case, the module of The MCM command must select another group (for example the one associated with the second largest distribution) and generate a display command designating the poster Ai associated with that group in the MCR correspondence table (if its personal quota has not been not already reached).

FIG. 7a illustrates a nonlimiting example of a day information display quota table in the case of a display medium SA containing three posters A1, A2 and A3, respectively for three displays AV, A2 'and A3. Each time a poster Ai of the display medium SA is displayed, its effective display time is counted from the maximum display time recorded in the quota table. When an Ai poster has been displayed for an effective duration greater than or equal to its maximum display time, it can no longer be displayed for the current period. By cons, when the given period (here the day) is expired, several situations can appear:

the manager of the service server SS can memorize new data in the quota table,

- it may be decided, in the absence of any outside intervention, to reset the display times to their initial respective values, - it may be decided to memorize new advertising information corresponding to new advertisers and to reset the durations display at their respective initial values for advertisers for whom the information has not been changed.

It will be noted that the processing module MR of the display medium SA may comprise means for transmitting / receiving data, preferably short-range, in order to broadcast at least in the first zone Z1 (in its position P (ti +1)) the information to display. Thus, each mobile terminal Tj of a target person can, if it is equipped with means for receiving short-range data, receive the information that is broadcast by the neighboring SA display medium. This significantly increases the likelihood that the target person will observe the information displayed. The short-range transmission technology that is used can be of any type, including RFID, Bluetooth, WiFi or infrared for example. Reference is now made to FIGS. 8a and 9a to describe a second embodiment of the system according to the invention.

More specifically, the invention proposes to implement at least the MCM control module in a management device D housed in a display medium SA (as shown in Figure 8a) or connected to the latter.

In this case, the control module MCM receives from a calculation module MCL the definitions of the distributions of the target persons considered as present in the first zone Z1 associated with its display medium SA and can implement the same functions as those described above with reference to Figures 1a to 7a. It is thus at least responsible for causing the display medium to display at least one piece of information corresponding to the characteristic (s) of one of the groups of target persons in which the target persons are distributed. to be present in the first zone Z1 in its predicted position P (ti + 1), according to the number of target persons it groups compared with those of the other groups (the selected group comprising at least two target persons), as well as possibly depending on minimum quota and / or maximum information that must be displayed over a given period.

The group definitions and the local correspondence table between the groups and the available posters Ai can for example be transmitted by the service server SS and stored by the management device D in a memory MS4 accessible to the control means.

As illustrated in FIG. 9a, the management device D may also comprise an MCL calculation module responsible for distributing among the groups the target persons whose presence has been determined individually (as well as possibly collectively by means of the predictive information) in the first zone Z1 in its predicted position P (ti + 1) by the locating means ML3 and ML4. In general, the calculation module MCL can implement the same functions as those described above with reference to Figures 1a to 7a.

The management device D may also include a timer module MT responsible for making its possible calculation module MCL work according to a chosen period, as described above. In this second embodiment, the SS service server can be simplified since it no longer needs to understand a centralized control module. It now includes the correspondence module MCR storing the correspondence table between the group definitions and the posters Ai that can be displayed by each display medium SA duo management system, the possible definition module MD to define the groups to from the profiles, and the first memory MS 1 responsible for storing the profiles of the target persons.

This second embodiment is particularly well suited, although not exclusively, to the case where presence detection is carried out in each management device D for the first zone Z1 of its display medium SA.

Indeed, and as illustrated in FIG. 9a, the management device D may comprise a part of the locating means ML4, the other part ML3 of these locating means equipping at least some of the target persons and the possible vehicle VT ( comprising the display medium SA), for example inside their mobile terminal Tj.

More specifically, the ML3 portion consists of data transmission modules, preferably short-range. Each ML3 data transmission module equips a target person and is responsible for transmitting radio signals which are representative of the identity of that target person.

The management device D then comprises a data receiving module MER for capturing the radio signals emitted by the neighboring ML3 data transmission modules in order to communicate the data they comprise to the part ML4 of the location means. o The short-range transmission technology that is used can be of any type, including RFID, Bluetooth, WiFi or infrared, for example.

The ML4 part of the locating means is therefore responsible for estimating the distance separating the display medium SA, in its position P (ti) (since it receives the message at time ti), from the target person whose data transmission module ML3 has sent a radio signal received by the MER reception module. Knowing the definition of the perimeter of the first zone Z1 and its predicted position P (ti + 1), it can then determine whether the target person who transmitted the received radio signal is likely to be located in the first zone Z1 in its position. predicted P (ti + 1). If this is the case, the ML4 portion stores the identifier of the target person that is defined by the data of the received radio signal. He can then communicate this identifier to the calculation module MCL of his device D so that it takes into account in its distribution. This therefore requires the MCL calculation module to have access to the memory where the identifiers of the target persons are stored in correspondence of their respective profiles. As illustrated in FIG. 9a, the device D may comprise a memory MS5 intended to store the identifiers of the target persons in correspondence with their respective profiles. This memory MS4 is for example supplied with data by the operator of the mobile network RM, or by the service server SS. But, as a variant, it is conceivable for the calculation module MCL to provide the mobile network RM with the identifiers of the detected target persons so that it transmits back to it the definitions of the profiles which are respectively associated with these identifiers.

Note that in this second embodiment, it is not useful for the management system to include a calculation server SC. But, we can consider a variant in which this can be useful. Indeed, in order to avoid the transfer of partially confidential data between the mobile network RM and the management devices D, it can be envisaged that the latter do not comprise a calculation module MCL of decentralized type, but that a calculation module centralized is provided in the calculation server SC, as described above with reference to Figures 1a to 7a. In this case, each device D must transmit to the calculation server

SC the identifiers (identifiers which may be pseudonyms simply corresponding to a device while keeping the anonymity of its user) of the detected target persons so that it proceeds to the distribution then address this distribution to its MCM control module.

It can also be envisaged that the management devices D do not comprise a detection module ML4 of decentralized type, but that a centralized ML2 part of the locating means is provided in the calculation server SC, as described previously with reference to FIGS. at 7a. In this case, the mobile terminals Tj of the target persons must be equipped with a satellite positioning module ML1 (as previously described with reference to FIGS. 1a to 7a) and no longer with a short ML3 data transmission module. scope. It will be noted that in this second embodiment, as in the first embodiment, the transmission / reception module MER of the management device D can be arranged to broadcast at least in the first zone Z1 (in its predicted position P (ti +1)) the information to display. Thus, each mobile terminal Tj of a target person can, if it is equipped with means for receiving short-range data, receive the information that is broadcast by the neighboring SA display medium. This significantly increases the likelihood that the target person will observe the information displayed.

Moreover, at least in the case of the first embodiment, it is conceivable that one of the display media SA of the management system is responsible for receiving for it and for other display media messages containing the display commands (as well as any definitions or descriptors of the information to be displayed) from the SS service server, and that it be responsible for broadcasting them by radio waves).

In a variant, it is possible to envisage a mode of transmission (propagation) step by step of the messages containing the display commands (as well as any definitions or descriptors of the information to be displayed) coming from the service server SS.

In one case as in the other, the transmission and reception can for example be done on a given band (for example VHF), the transmission being further in TDMA mode synchronized to the pulse

GPS, for example. The reception can be done continuously, each message then containing the references of the display medium ensuring the relay and the data broadcast. This mode of operation can also be used to modify the information stored in the SA display media or the correspondence between descriptors and information, in particular when they comprise a digital display screen. This information can for example be provided by means of a short-range transmission technique by a technical agent who circulates in a vehicle equipped with a discount station.

In the foregoing, there is described an exemplary implementation of the invention in which a single display medium SA was mounted on a vehicle VT. But, the vehicle VT can comprise at least two distinct faces on which can be mounted two display supports SA1 and SA2 respectively attached to first zones Z1 and ZV distinct which follow its trajectory TR. In this case, the location means ML1 and ML2 (or ML3 and ML4) are responsible for determining the presence in the given time interval of target persons in each of the first zones Z1 and ZV. For its part, the calculation module MCL is responsible for distributing in a first set of groups EG1 the target persons whose presence has been determined in one of the first two zones Z1 or ZV, and in a second set of groups EG2 ( not necessarily identical to the first EG 1) the target persons whose presence has been determined in the other of the first two zones ZV or Z1. In addition, the control module MCM is responsible for causing each of the two display supports SA1 and SA2 to display at least one piece of information that corresponds to the characteristic (s) of one of the groups of the group. corresponding set EG 1 or EG2, chosen according to the number of target persons it groups compared with those of the other groups of the same set EG1 or EG2.

All or part of the various modules constituting the management device D, the service server and the calculation server, according to the invention, can be implemented in the form of electronic circuits, software (or computer) modules, or a combination of circuits and software.

It will also be noted that the invention may optionally be implemented on a first part of trajectory L1, and once it has arrived in a selected zone, containing a second portion of trajectory L2 and characterized, for example, by a famous commercial sign or a famous brand which is known to be familiar to many target persons (circulating in said chosen zone), one switches to an autonomous mode of displaying advertisements or messages which does not rely on the notion of groups and criteria but on the contrary relies on the display of advertisements or messages stored in a memory corresponding to said zone.

To implement this autonomous display mode, it is necessary to use i) means for locating the vehicle (such as for example a GPS implanted in said vehicle) in order to determine when this vehicle reaches a second path portion L2 of a vehicle. zone listed, ii) storage means (located in said vehicle and coupled to the internal display means) for storing advertisements and / or messages in correspondence of positions (or identifiers) of zones, and iii) implanted control means in said vehicle, for displaying on the latter (on the outer panels) an advertisement or a message corresponding to the place in which it is momentarily located. It should be noted that new content of advertisements or messages may be transmitted to the vehicle by radio to supplement or overwrite the old contents.

It will also be noted, as is schematically illustrated in FIG. 10a, that the service server SS can be connected (or coupled, for example via the mobile communication network RM) to equipment EA1 ', EA2', EA3 ', 'AT, A2', A3 '(Ak') advertisers responsible for defining, for each advertiser respectively, data of any type comprising information to be displayed, target target person profiles and sets of relevance criteria (as presented hereinafter according to one embodiment). In this case, the equipment EA1 ', EA2', EA3 'feeds the definition module MD, by own reception inputs not shown, to characterize the aforementioned groups. The definition module MD then provides the definitions of these groups to the calculation module MCL. Such an SS service server may belong in particular to an advertising agency or an advertising broker managing advertising space.

DISPLAY STAND (S) IMPLANTES IN PUBLIC TRANSIT VEHICLES Here, the term "display medium" is understood to mean a material implanted in a selected location of a public transport vehicle and intended to support a poster, possibly of a advertising, or to display information (or information), possibly of an advertising nature, and then to maintain this poster or information (or information) in a given position and for a given period of time so that it can be (are) observed by passengers of the vehicle (public transport).

Advertising in a (public transport) vehicle is traditionally carried by media such as billboards or display screens (for example with light-emitting diodes (LEDs) or plasma), in particular placed in places where they are in visibility of many passengers. These advertisements may have been affixed by gluing on the media. There are also media with several posters scrolling in turn, or selectable in a "tank" and displayed on the face of the support for a predetermined time. The invention relates to media for selecting one of several displays or display on a screen information, information, an image or a video clip.

The display companies (so-called billboards) have at their disposal display networks and offer their advertising customers qualified displays according to the target sought. The rating of the display networks is a standard parameter for advertisers and viewers through a particular nomenclature that generally divides the population into five social level layers (A, B, C, D, E): thus, if the advertiser is interested in targeting a cadre population, it will require category "B"targeting; a senior management population will correspond to category "A" targeting, etc. For example, a Category A signage network is often located in a large city, near business offices or residential neighborhoods. However, the qualification of the display networks remains limited to the predefined categories and there is no other technical means of targeting the audience. At most, some advertisers may have surveys done on the spot, that is, close to the advertising medium, to know the profile of the individuals passing by and the impact that this advertisement has left in their minds. This single way of measuring targeting is very little used because it is expensive and provides the opinion of only a very limited panel of people (very) unrepresentative of the entire population. It is difficult to conduct surveys of public transit passengers. In addition, it does not respond quickly, given the time required to obtain and analyze the results of opinion surveys.

The purpose of the present invention is therefore to solve the problem set out above in order to provide a more precise targeting that is as much as possible in affinity with the passengers of the public transport vehicles.

For this purpose, the invention proposes a system dedicated to managing the display of information on at least one display medium implanted inside a public transport vehicle in visibility of its passengers, and comprising in addition :

locating means for determining the presence among the passengers located near the support of target persons associated with profiles defined by objective and / or subjective characteristics,

first storage means responsible for storing the profiles of the target persons,

calculation means responsible for distributing in groups, which are each defined by at least one profile characteristic, the target persons whose presence has been determined inside the vehicle in the vicinity of the display medium; correspondence between the groups and information to be displayed, and

control means responsible for causing the display medium to display at least one piece of information corresponding to the (x) characteristic (s) of one of the groups chosen according to the number of target persons it groups compared to those of the other groups, the chosen group comprising at least two target persons.

The invention thus has a dual function, the first is that of analyzing the average profile of the public attending an area located near a display medium (for example, if the public has been previously qualified

"AB", the invention makes it possible to verify it, or even to refine the qualification), and the second is that of the targeting of the public according to the result of the analysis obtained, in order to provide to said audience information corresponding to a at least part of its average profile.

In this way, the invention makes it possible to achieve the objective desired by any advertiser, namely the targeting of the public by micro-segmentation and the display of really useful information, thus ensuring the optimization of the advertisers' budget. It should be noted that, since the invention is based on the concept of groups, it makes it possible to provide a technical solution to the dual technical problem of prohibiting the use of personal data of target persons (such as users) and the technical unavailability, for certain actors in the economic circuit, of this personal data in their databases. Indeed, because of the prohibition or refusal to commercially exploit this personal data, customer files can not be transmitted to economic partners, for example mobile operators can not transmit such files to customers. service providers. Due to the obstacle created by this unavailability, the targeting of the advertising data was, in the prior art, reduced.

It is essential to understand that the calculation, according to the invention, intended to distribute the target persons in groups, implies a priori a plurality of people per group (the same target person can be in several groups at the same time, the profile characteristics used for the distribution are not necessarily exclusive). However, a group may be reduced to singleton (a group with only one target person). In this case, so preferential, the invention does not automatically exclude this group-singleton before the display. It is only during the control step responsible for causing the display medium to display that it will be verified that the selected group comprises at least two target persons. The singleton group can not be the subject of the chosen group. Alternatively, it may be possible to automatically exclude all singletons before ordering. Therefore, it is ensured that the selected group will in any case be of a composition greater than or equal to two target persons.

its control means may be responsible for causing the display medium to display at least one piece of information corresponding to the characteristic (s) of one of the groups chosen according to the number of target persons that it groups compared to those of the other groups and according to minimum quota and / or maximum information to display on a given period;

the display medium may comprise means for transmitting / receiving short-range data intended to diffuse into the vehicle near the display medium the information to be displayed. In this case, each mobile communication terminal (equipping a target person) comprises means for receiving short-range data responsible for receiving the information broadcast by the display medium; it may comprise second storage means responsible for storing the geographic positions of the target persons and the display medium;

it may comprise prediction means responsible for determining, based on predictive information, target persons different from those individually detected in the vehicle in the vicinity of the display medium. Its calculation means are then responsible for distributing in the groups the individually detected target persons as well as the target persons determined by the prediction means;

each display medium may comprise a poster loading block, a mechanism for selecting one of the posters to be loaded and a mechanism for displaying a selected poster so that it is visible to at least the target persons who are located inside the vehicle near the display bracket; alternatively, a display medium may comprise a digital display screen.

The device according to the invention may comprise other characteristics that can be taken separately or in combination, and in particular:

its control means may be responsible for causing the display medium to display at least one item of information corresponding to the characteristic (s) of one of the groups, chosen according to the number of target persons that it groups in comparison with those of the other groups and according to minimum quota and / or maximum of information to be displayed over a given period;

- Figure 10b schematically illustrates a service server connected to three announcers equipment.

Reference is first made to FIG. 1b to present an information display management system according to a first embodiment of the invention.

As illustrated in FIG. 1b, a management system according to the invention comprises at least one display medium SA implanted in a public transport vehicle VT, means for locating target persons ML1 and ML2 (or ML1, ML3 and ML4), a first memory MS1, a correspondence module MCR, a calculation module MCL and an MCM control module. In what follows we consider only the case of a management system comprising a single display medium SA installed in a VT public transport vehicle, to simplify the description of the invention. However, the invention applies to any management system comprising at least a display medium SA. Furthermore, the invention applies to at least one public transport vehicle VT, and preferably to one or more fleets of public transport vehicles VT, such as for example buses, coaches, trains or subways. .

In what follows, it is considered as a purely illustrative example that the display medium is located inside a bus VT. The latter is driven by a CV conductor and comprises, for example, a PE access door, allowing passengers to climb in, and a PS exit door (possibly confused with the PE access door), allowing passengers to exit.

But, the invention is not limited to this type of information. It also concerns the display of information relevant to a given population. The display medium SA is fixedly implanted in a selected location of the VT bus. This is for example an advertising panel comprising a block (or mechanism) loading MA in which is stored (for example by stacking) a set of advertising posters Ai. For example, the loading block MA comprises three posters A1 to A3 (i = 1 to 3) which it is responsible for displaying (or presenting) on a visible window of passengers through a mechanism, individually, or by pair (see even by triplet), according to a command adapted for this purpose.

It should be noted that the invention is not limited to this type of display medium. It concerns indeed any type of display medium, capable of displaying on command information or information, including scrolling displays or display screens LED or plasma, for example. The (digital) display screens make it possible to avoid all the mechanics of storage and display. In addition, they may optionally transmit the data defining the information to be displayed with the display command. An example of a digital display medium is schematically illustrated in Figure 2b. It comprises in particular an EA digital display screen, a memory responsible for storing data defining at least information to be displayed, and a processing module

MR capable of receiving display commands (as well as possibly programming data and / or data defining information to display or descriptors information to display).

The locating means ML1 and ML2 (or ML1, ML3 and ML4) are responsible for determining the presence of target persons among the passengers of the VT bus which are located near the display medium SA.

By "target person" is meant here a person to whom a profile defined by one or more objective and / or subjective characteristics has been associated. Among the objective characteristics that can be used, mention may in particular be made of the number of past passes in front of the display medium SA concerned, the number of visualizations of each of the advertising posters, and the like. Among the subjective characteristics that can be used, mention may be made of gender, age, socio-professional category, profession, areas of professional and / or personal interest, and the like.

In general, any type of criterion (or characteristic) can be used to define a profile. It should be noted that the profiles can be advantageously defined from the profiles used by the communication network operators to target their customers.

The first memory MS 1 is responsible for storing the profiles of the target persons.

The calculation module MCL is responsible for distributing, in selected groups, the target persons whose presence has been determined inside the VT bus in the vicinity of the display medium SA by the localization means.

ML1 and ML2 (or ML1, ML3 and ML4). By "group" is meant here a set defined by at least one profile characteristic. Note that different groups are defined by combinations of different characteristics. Moreover, it will be noted that a group can be defined by all the characteristics of a profile, or even of several profiles.

The correspondence module MCR is responsible for establishing matches between the groups (linked to the profiles that are stored in the first memory MS1) and the information that must be displayed by the display medium SA. In other words, in the example described, the correspondence module MCR stores a correspondence table between the groups and the advertising posters Ai which respectively correspond to them.

The control module MCM is responsible for causing the display medium SA to display at least one piece of information corresponding to the

(or to) characteristic (s) of a group that is chosen at least according to the number of target persons it groups compared to those grouped by other groups. This selected group includes at least two target individuals. If after a first attempt, a chosen group includes only one target person, then we take the next group that includes minus two target people.

For example, and not limitation, the MCM control module may cause the display medium to display at least one item of information corresponding to the characteristic (s) of the group that groups the largest number of target persons. . In other words, when the MCM control module receives from the calculation module MCL the distribution on the different groups (linked by the correspondence table to the various posters Ai available) of the target persons who are considered to be present within the VT bus near the display medium SA, it selects the group that is associated with the largest percentage and generates a display command to the SA display medium concerned so that it proceeds to display the displays Ai corresponding to this group selected in the correspondence table (MS1).

It is recalled that, in the presence of digital display screens EA (see FIG. 2b), it is possible to envisage that the display control comprises the data defining the information to be displayed or, more simply, a descriptor (or identifier) of the information to be displayed (to avoid network overload during transmission). This descriptor is converted by the processor (or processing module) MR, which includes the display medium SA (and which is responsible for translating the display command received into instruction (s) understandable (s) by the mechanism of display MA), in information data to be displayed, for example by means of a correspondence table between different descriptors and information (advertising) to be displayed. In the nonlimiting example illustrated in FIG. 1 b, the control module MCM, the first memory MS1 and the correspondence module MCR, as well as the eventual group definition module MD are located in a service server SS. Moreover, in the nonlimiting example illustrated in FIG. 1 b, the calculation module MCL and part of the locating means ML2 are located in a calculation server SC. A complementary part of the locating means ML1 is distributed in mobile communication equipments Tj carried by at least some of the target persons as well as the display medium SA implanted in the bus. VT.

More precisely, in the nonlimiting example illustrated in FIG. 1b, the display medium SA and at least some of the target persons are equipped with a mobile communication terminal Tj (here j = 1 to 4) in which has implanted an ML1 satellite positioning module. For example, the mobile communication terminals Tj are mobile phones that are connected to an RM mobile (or cellular) communication network. The latter is for example a GSM / GPRS network ("Global System for Mobile Communications / General Packet Radio Service" in English) whose cells are managed by base stations (called BTS (for "Base Transceiver Station" in English)) . Of course, the cellular communication network can be of any other type since it allows the establishment of communications by waves (radio and / or hertzian - terrestrial and / or satellite). Therefore, it may be a UMTS network ("Universal Mobile Telecommunications Service" in English) whose base stations are called Nodes B, or a wireless LAN type WiFi or WiMAX, for example .

It will be noted that the calculation server SC preferably belongs to the operator of the mobile network RM. It is recalled that a satellite positioning module ML1 is responsible for delivering position measurement estimates of the equipment in which it is implanted, based on signals transmitted by a constellation of positioning satellites of a positioning network. type RNSS (for "Radio Navigation Satellite Service" in English), or GNSS, such as the GPS network, or the GLONASS network, or the future GALILEO network. It will be noted that the accuracy of the position measurements can be enhanced when the constellation of positioning satellites is coupled to a so-called "augmentation" system, of the SBAS (for Satellite Based Augmentation System) type, such as the EGNOS system.

Each satellite positioning module ML1 transmits the positioning data that it determines to a server of the network which is responsible for storing them in a database of information relating to customers of the operator of the RM mobile communication network. This database can be the HLR (Home Location Register) if the subscriber is connected to the radio access network of his home network or the VLR (Visitor Location Register) if the subscriber is connected to the radio access network of another operator than his own.

In the nonlimiting example illustrated in FIG. 1b, the positioning modules ML1, implanted in the mobile terminals Tj of the target persons and of the display medium SA, transmit their geographical positions to their mobile network RM. The ML2 part of the location means, here implanted in the calculation server, is then arranged to access the HLR information database in order to determine the geographical position of the display medium SA, then all the identifiers of the subscribed customers. whose geographical position is substantially identical to that of the display medium SA. The identity here must be understood in relation to the area which at least partially surrounds the display medium SA and not with respect to the extent of the public transport vehicle VT which comprises this display medium SA. Indeed, some public transport vehicles may include several remote display media and which must each have a mobile terminal Tj provided with a "GPS" module ML1.

Preferably, the ML2 compares only the geographic positions of the target persons designated by the service server SS to the geographical position of the display medium SA, and each time it detects an "identity" corresponding to a target person, it records the identifier of the corresponding target person.

In a variant, it can be envisaged that the identifiers of the target persons and of the display medium SA and the corresponding geographical positions are periodically stored in a memory MS3 of the calculation server SC. In this case, the ML2 part has only to make its comparison from the geographical positions stored in the memory

MS3.

Whenever the ML2 party has determined all the target people who are present in the VT bus near the display medium SA, preferably in a given time interval, it communicates their identifiers to the calculation module MCL. The latter can then divide into the groups, the definitions of which have been communicated to it by the service server SS and which are for example stored in a second memory MS2 with the definitions of the profiles, the target persons whose presence has been determined in the VT bus near the SA display rack. Then, it transmits to the control module MCM a message comprising the distribution of the target persons on the different groups.

Over a period of time IT elapsed, the ML2 part of the location module has determined that 50 people were present in the VT bus near the display medium SA, while the latter is circulating, for example, in a business district. . For example, it may be agreed between the SS service server manager and his / her advertiser clients to make a selection according to selected criteria, such as, first of all, sex and then the socio-professional category. Groups have therefore been formed from these criteria, and then transmitted to the calculation server SC (RM mobile network operator holder of personal information on these customers). An example of a breakdown into groups and subgroups is given in the following table.

It will be noted, as illustrated, that the calculation server SC may for example comprise a timer module MT responsible for making the calculation module MCL work according to a chosen period, rather than almost continuous way.

MCM holds that the most represented population in the VT bus near the display medium SA is the female population of socio-professional category A. By accessing the correspondence table MS1, the control module determines that the socio-professional category A for example, an advertising poster Ai of an advertiser relating to jewelery or high-end cosmetics.

In the example described with reference to FIG. 1b, the display control is transmitted to the display medium SA via the mobile network RM to which its mobile terminal T4 is connected.

Note also that the detection of presence may also relate to passengers of the vehicle VT who do not have a mobile terminal Tj, but for which there is information predictive, including the means of public transport VT that they use regularly and according to regular schedules, such as buses, subways, trains or buses, whose routes are generally predetermined and subject to fixed schedules. We can indeed know if people use a public transport vehicle every day at the same time on the same line. Therefore, for these target persons it is not necessary that they have a means of localization, as for example an ML1 satellite positioning module. Their presence inside a VT public transport vehicle can be predicted thanks to the predictive information of the public transport network (relating to the habits of the target persons and to the VT vehicle journeys).

The ML2 part of the location means must then comprise a prediction module responsible for determining the target persons, who are not equipped with a mobile terminal Tj but who are likely to be present in the VT bus near the support of SA display, based on predictive information provided by operators of the transport networks and for example stored in memory MS2 or MS3.

In this case, the calculation module MCL is responsible for distributing in the groups defined by the manager of the service server SS the target persons detected individually in the VT bus near the display medium SA (via their positioning modules ML1). as well as the target persons determined by the prediction module of the ML2 part.

As indicated above, the control module MCM is responsible for causing the display medium to display at least one item of information corresponding to the characteristic (s) of one of the groups, chosen according to the number of target groups it groups compared to those of the other groups (this selected group comprising at least two target persons). But, it can also make its choice based on minimum quota and / or maximum information that must be displayed over a given period. Indeed, the final selection of the advertising poster to be selected can be made according to a minimum quota of posters that should be displayed over a given period (for example over a day) to avoid discriminating against certain advertisers who may to be poorly represented and / or to respect certain contractual commitments with them. These quotas are for example defined in a quota table stored in a memory of the SS service server.

Thus, to use the example presented in the previous table, if several successive determinations led to the selection of the same displays Ai (same result (female population of socio-professional category A}), then the MCM control module must check if minimum / maximum quotas have been defined. If this is the case, the control module MCM must select another group (for example that associated with the distribution the second largest) and generate a display command designating the poster Ai associated with this group in the correspondence table. MCR (if his personal quota has not already been reached).

FIG. 3b illustrates a nonlimiting example of a day information display quota table in the case of a display medium SA containing three posters A1, A2 and A3, respectively for three displays AV, A2 'and A3. Each time a poster Ai of the display medium SA is displayed, its effective display time is counted from the maximum display time recorded in the quota table. When an Ai poster has been displayed for an effective duration greater than or equal to its maximum display time, it can no longer be displayed for the current period. By cons, when the given period (here the day) is expired, several situations can appear:

the manager of the service server SS can memorize new data in the quota table,

- it may be decided, in the absence of any outside intervention, to reset the display times to their initial respective values,

It will be noted that the processing module MR of the display medium SA may comprise data transmission / reception means, preferably short-range, in order to broadcast in the VT bus near the display medium SA the information to display. Thus, each mobile terminal Tj of a target person can, if it is equipped with means for receiving short-range data, receive the information that is broadcast by the neighboring SA display medium. This can significantly increase the likelihood that the target person is observing the information displayed. The short-range transmission technology that is used can be of any type, including RFID, Bluetooth, WiFi or infrared for example.

Referring now to Figures 4b and 5b to describe a second embodiment of the system according to the invention.

This second embodiment takes up almost all the elements (modules) constituting the system described above, while changing the location of part of them.

More specifically, the invention proposes to implement at least the MCM control module in a management device D housed in a display medium SA (as shown in Figure 4b) or connected to the latter.

In this case, the control module MCM receives from the calculation module MCL the definitions of the distributions of the target persons considered as present in the VT bus in the vicinity of the display medium SA and can implement the same functions as those described. above with reference to Figures 1b to 3b. It is thus at least responsible for causing the display medium to display at least one piece of information corresponding to the characteristic (s) of one of the groups of target persons in which the target persons whose the presence has been determined in the VT bus near the display medium SA, according to the number of target persons it groups compared with those of the other groups (this selected group comprising at least two target persons), as well as possibly based on minimum quota and / or maximum information that must be displayed over a given period. The group definitions and the local correspondence table between the groups and the available posters Ai can for example be transmitted by the service server SS and stored by the management device D in a memory MS4 accessible to the control means MCM. In this second embodiment, the display medium is considered to be of digital type, like that presented previously with reference to FIG. 2b. But, it can also be a "mechanical" display medium, storing Ai posters, of the type presented. previously with reference to Figure 1b.

As illustrated in FIG. 5b, the management device D may also comprise an MCL calculation module responsible for distributing in the groups the target persons whose presence has been determined individually (as well as possibly collectively thanks to the predictive information) in the VT bus near the display medium SA by the locating means ML1, ML3 and ML4. In general, the calculation module MCL can implement the same functions as those described above with reference to FIGS. 1b to 3b. The management device D may also include a timer module MT responsible for making its possible calculation module MCL work according to a chosen period, as described above.

In this second embodiment, the SS service server can be simplified, since it no longer needs to understand centralized control module. It now comprises the correspondence module MCR storing the correspondence table between the group definitions and the posters Ai that can be displayed by each display medium SA of the management system, the optional definition module MD making it possible to define the groups to be defined. from the profiles, and the first memory MS1 responsible for storing the profiles of the target persons.

This second embodiment is particularly well suited, although not exclusively, to the case where presence detection is carried out in each management device D for the associated display medium SA.

Indeed, and as illustrated in FIG. 5b, the management device D may comprise a part of the locating means ML4, the other part ML3 of these locating means equipping at least some of the target persons, for example inside of their mobile terminal Tj.

More specifically, the ML3 portion consists of data transmission modules (active), preferably short-range. Each ML3 data transmission module equips a target person and is responsible for transmitting radio signals that are at least representative of the identity of that target person. He could also transmit the profile associated with this identifier. The management device D then comprises a data receiving module MER for capturing the radio signals emitted by the neighboring ML3 data transmission modules in order to communicate the data they comprise to the part ML4 of the location means. The short-range transmission technology that is used can be of any type, including RFID, Bluetooth, WiFi or infrared for example.

The part ML4 of the locating means is thus loaded, whenever the data receiving module MER receives radio signals emitted by a data transmission module ML3, of recording at least the identifier which is contained in these signals. radio and designates a target person. This recording means that the "sending" target person is considered by the ML4 part as present inside the VT vehicle in the vicinity of the display medium SA. The part ML4 can then communicate this identifier to the calculation module MCL of its device D so that it takes into account in its distribution. This therefore requires the MCL calculation module to have access to the memory where the identifiers of the target persons are stored in correspondence of their respective profiles. As illustrated in FIG. 5b, the device D may comprise a memory MS5 intended to store the identifiers of the target persons in correspondence of their respective profiles. This memory MS5 is for example supplied with data by the operator of the mobile network RM, or by the service server SS. But, as a variant, it is conceivable for the calculation module MCL to provide the mobile network RM with the identifiers of the detected target persons so that it transmits back to it the definitions of the profiles which are respectively associated with these identifiers.

Note that in this second embodiment, it is not useful for the management system to include a calculation server SC. House can consider a variant in which this can be useful. Indeed, in order to avoid the transfer of partially confidential data between the mobile network RM and the management devices D, it can be envisaged that the latter do not comprise a calculation module MCL of decentralized type, but that a calculation module centralized is provided in the calculation server SC, as described above with reference to Figures 1b to 3b.

In this case, each device D must transmit to the calculation server SC the identifiers of the detected target persons so that it proceeds with the distribution and addresses this distribution to its MCM control module. It can also be envisaged that the management devices D do not comprise a detection module ML4 of decentralized type, but that a centralized ML2 portion of the locating means is provided in the calculation server SC, as described previously with reference to FIGS. b to 3b. In this case, the mobile terminals Tj of the target persons must be equipped with a satellite positioning module ML1 (as described previously with reference to FIGS. 1b to 3b) and no longer with a short ML3 data transmission module. scope.

Note that in this second embodiment, it is preferable that each data transmission module (active) ML3 periodically sends radio signals to the device D so that it knows if the target person it is teaming is still present in the VT bus and close to the display bracket. Thus, as long as the device D receives radio signals from a data transmission module ML3, it continues to take into account in its distribution the target person it equips. On the other hand, as soon as it no longer receives radio signals from an ML3 data transmission module, it ceases to take into account in its distribution the target person it equips.

Reference is now made to FIGS. 6b and 7b to describe a third embodiment of the system according to the invention. This is actually a variant of the second embodiment described above with reference to Figures 4b and 5b.

What differentiates this third embodiment from the second is mainly the means of locating the target persons. More specifically, in this third embodiment the detection is at the initiative of the ML4 parts' locating means, located in the VT bus, and no longer at the initiative of the ML3 part of the locating means as in the case of the second embodiment. The (at least some) of the target persons are now equipped with a part ML3 'of the passive type of locating means. Each ML3 'part is for example a smart card in which are stored personal data representing at least the identifier of the target person who holds it and which can be read at least in part by the ML4' part of the (or coupled au) management device D.

Note that the memory of this smart card, which may be, for example, the transport card of the target person, can also store data representative of the profile that is associated with said target person. The VT bus is now equipped with ML4 'part (s) responsible for reading at least the personal data which represent the identifiers of the target persons who hold them when they have penetrated inside the VT bus via a PE access door. (arrow F1). Any type of reading method known to those skilled in the art can be used. For this purpose, it is possible for example to place an entry detection gantry at each access gate PE. Once the identifier read, it is stored by the party ML4 'which has detected. The target person designated by this stored identifier is then considered to be present inside the VT bus, close to the display medium SA. Then, the ML4 'part transmits the stored identifier to the management device D so that the MCL calculation module takes it into account in its distribution. The transmission can be carried out by wire or by wave (in this case, the device D must comprise a data receiving module MER charged to pick up the radio signals emitted by each part ML4 'to transmit the identifiers (to less) read). The transmission technology that is used can be of any type, including RFID, Bluetooth, WiFi or infrared, for example.

If the ML4 'part only reads and transmits the identifiers, the MCL calculation module must have access to the memory where the identifiers of the target persons are stored in correspondence with their profiles. respectively. As illustrated in FIG. 7b, the device D may comprise a memory MS5 intended to store the identifiers of the target persons in correspondence with their respective profiles. This memory MS5 is for example supplied with data by the operator of the mobile network RM, or by the service server SS. But, as a variant, it is conceivable for the calculation module MCL to provide the mobile network RM with the identifiers of the detected target persons so that it transmits back to it the definitions of the profiles which are respectively associated with these identifiers. On the other hand, if the part ML4 'reads and transmits the identifiers and the associated profiles (because they are stored in the ML3' smart card), the calculation module MCL no longer needs to have access to the memory where the identifiers of the target persons are stored in correspondence of their respective profiles. Once the MCL calculation module has the associated identifiers and profiles, it can proceed with the distribution and then communicate the distribution to the MCM control module so that it generates an appropriate display command.

Note that in this third embodiment, it is preferable to provide auxiliary detection means MDA responsible for detecting the identifier of a target person when leaving the bus VT. For this purpose, it is possible, for example, to use MDA detection gates located in the vicinity of the PS output gates (which are possibly the same as the PE access gates). Each MDA output detection portico is then responsible for reading in the ML3 'smart card of the person who leaves the VT bus by a PS exit door (arrow F2), the identifier that it stores, in order to communicate it. to the management device D, and more specifically to its calculation module MCL. Thus, as long as the device D does not receive from an MDA output detection gantry an identifier identical to that previously received from an ML4 'input detection gantry, it continues to take into account in its distribution the target person who is associated with this identifier. On the other hand, as soon as it receives from an MDA output detection portico an identifier identical to that previously received from a gantry of ML4 'input detection, it stops to take into account in its distribution the target person who is associated with this identifier.

It should be noted that in all embodiments the transmission / reception module MER of the management device D can be arranged to broadcast the information to be displayed at least in the area near the display medium SA. Thus, each mobile terminal Tj of a target person can, if it is equipped with means for receiving short-range data, receive the information that is broadcast by the neighboring SA display medium. This significantly increases the likelihood that the target person will observe the information displayed.

Moreover, at least in the case of the first embodiment, it is conceivable that one of the display media SA of the management system is responsible for receiving for it and for other display media messages containing the display commands (as well as any definitions or descriptors of the information to be displayed) from the SS service server, and that it is responsible for broadcasting them by radio waves.

In one case as in the other, the transmission and reception can for example be done on a given band (for example VHF), the transmission being further TDMA mode synchronized to the GPS pulse, for example. The reception can be done continuously, each message then containing the references of the display medium ensuring the relay and the data broadcast.

This mode of operation can also be used to modify the information stored in the SA display media or the correspondence between descriptors and information, in particular when they comprise a digital display screen. This information can for example be provided by means of a short-range transmission technique by a technical agent who circulates in a vehicle equipped with a discount station. All or part of the various modules constituting the management device D, the service server and the calculation server, according to the invention, can be implemented in the form of electronic circuits, software (or computer) modules, or a combination of circuits and software. It should be noted that the invention can be implemented in any type of public transport means, and in particular in those for which there is a system of pre-reservation of places, such as trains and aircraft. In this case, the system of pre-reservation seats plays the role of location means since the place (seat or berth) allocated to a person has a predefined position. In addition, the system for pre-booking seats plays the role of interface with an application server to know the profile of at least some of the customer.

It will furthermore be noted that the invention advantageously makes it possible to use smart cards carried by target persons and able to exchange (receive and supply) information via waves with a radio-frequency detector, such as for example radio cards. transport (or access cards) type Navigo ®. The radio-frequency technology used can be, for example, that recommended in the ISO 14443 standard or a very short-range technology, for example of the NFC (Near Field) type.

Communication "- near field communication).

For example, and as is schematically illustrated in FIG. 8b, it is possible to install radio frequency detectors DR, for example of the RFID type, on each internal side of a door PO for access to a wagon (subway, bus). train, tram or bus) WA and / or on at least some of the standing help bars (or other equipment) located inside the cars in transit areas. The more a DR detector is planned in a wagon WA, the more the probability of interacting with the radio-frequency smart cards CA of the users (target persons) who enter this Wagon WA.

Since a target person must necessarily pass in front of at least one of the DR detectors, his radio frequency smart card CA is forced to interact with one of these detectors DR. Therefore, the manager of the The user tracking information management system is able to know that this target person has entered a given wagon WA and thus determine his position at a given moment.

In a variant schematically illustrated in FIG. 9b, radio frequency detectors DN, for example of the NFC type, may be installed on sliding doors PO 'located on quay QU. These sliding doors PO 'open automatically when the access doors of the cars (subway or train) are immobilized along said wharf QU opposite them. Alternatively, the radio frequency detectors DN can be installed on gantries located on the quay QU. The access doors of the wagons (subway or train) must indeed stop along said wharf QU next to the porticoes. In yet another variant, it is possible to install (integrate or report) radio-frequency detectors DN on the external faces of the access doors of the wagons WA. In yet another variant (not shown), the CA chip card locating means can be implanted in terminals (at least one per wagon WA) capable of reading the radio frequency RF chip cards once the doors of the car WA closed.

DN detectors are very short range, typically a few centimeters, the interaction between a DN detector and a target person's CA smart card therefore depends on the decision of the latter since the CA smart card must be approached nearby of the DN detector. In particular, to encourage target people to report their presence by interacting their CA smart card with DN sensors, we can consider granting them, in return, benefits and / or credits of any type, and by example on their next transport subscription or on purchases of items or tickets for shows or museums (in collaboration with partners of the economic circuit).

It will be understood that each DR or DN detector is connected to the tracking management system so that the DR or DN detector provides the tracking information management system with its own identifier (to know its location) and a target person identifier. obtained when interacting with his CA smart card (and allowing access to his profile). Thanks to these AC smart cards and these radio-frequency detectors DR or DN, the display can be adapted according to the parts (parts) of wagons WA in which they are momentarily located of the detected target persons. Whatever the type of radio-frequency technology used, it can be envisaged that the smart cards (or access cards) CA comprise, on the one hand, means of radio-frequency communication allowing them to receive at least one piece of information. known as a date, a metro (or railway) line, and a wagon number, and to issue the identifier of the target person carrying the card, and secondly, storage means for storing this travel information. The skilled person can adapt any compatible communications protocol to convey the travel information and the person identifier. Thus, the dealer of the metropolitan (or railways) no longer has to store the files containing the information about the target people, then to transmit them to its partners offering services.

The partner can then recover at least some of the information stored in the CA smart cards (or access cards), and more specifically those which concern it, thanks to an information collection device, possibly of radio-frequency type to very short range.

For example, the collection device may be a terminal (possibly dedicated) connected to a remote server and in which the CA smart card is inserted and responsible for recovering in its memory at least one travel information that is specific to the remote server. This information retrieval (s) can be done either at the request of the remote server after the CA smart card inserted into the terminal's smart card reading mechanism and after establishment of a link with said server, or automatically following the insertion of a CA smart card into the smart card reading mechanism of the terminal and then by transfer to the remote server. Preferentially, reading a travel information in a CA smart card causes the deletion of this travel information in the memory of said CA smart card. The idea here is to avoid that the same information is used more than once. The interest of this mode of operation is highlighted by the nonlimiting example described below.

A target person equipped with an AC chip card (of the type described above) enters a wagon WA and is detected by the management system during an interaction between its smart card CA and a detector DR or DN . From the profile of this target person detected, and the profiles of the other target persons also detected in the same wagon WA, the management system will display a targeted advertisement or message according to the invention. For example, the advertisement or the targeted message that is displayed in the wagon WA may indicate that the company X offers a reduction of y € to any target person presenting himself with his smart card (access card ) CA at checkout at one of his stores or restaurants to pay for a purchase. When a target person who has seen this message goes to a company X store or restaurant, they present their CA access card at checkout to pay for their purchase and benefit from the discount. According to a pre-established exchange protocol, the travel information (eg, travel date, metro line, car) stored in the CA access card is read by an appropriate reading device, and then by example, sent to the server of the company X which is dedicated to the application of reductions in partnership with the concessionaire of the transport network which posted the message in wagon WA. The server will then recognize that the travel information read corresponds to the advertising message "y € reduction" and gives permission for the reduction of y € to be granted to the target person concerned (customer). Once the reduction is granted, the travel information is removed from the memory of the CA smart card so that it can no longer be reused.

It should be noted that it is possible to envisage that only one travel information is stored for the same public transport line used during a given time interval, in order to avoid that the same person accumulates the same advantage several times over. interacting his CA smart card with several detectors of the same line. It is also conceivable that there is a ceiling limitation of accumulated benefits by the same target person.

It should also be noted that one can possibly implement the invention on a first part of trajectory L1, and once arrived in a chosen area, containing a second part of trajectory L2 and characterized, for example, by a famous commercial sign or a famous brand which is known to be familiar many target people (circulating in said chosen area), we switch to a standalone mode of display of advertisements or messages that does not rely on the notion of groups and criteria but on the contrary is based on the display of advertisements or messages stored in a memory corresponding to said zone. To implement this autonomous display mode, it is necessary to use i) means for locating the vehicle (such as for example a GPS implanted in said vehicle) in order to determine when this vehicle reaches a second path portion L2 of a vehicle. zone listed, ii) storage means (located in said vehicle and coupled to the internal display means) for storing advertisements and / or messages in correspondence of positions (or identifiers) of zones, and iii) implanted control means in said vehicle, for displaying in the latter an advertisement or a message corresponding to the location in which it is momentarily located. It should be noted that new content of advertisements or messages may be transmitted to the vehicle by radio to supplement or overwrite the old contents.

It will also be noted, as is schematically illustrated in FIG. 10b, that the service server SS can be connected (or coupled, for example via the mobile communication network RM) to equipment EAT, EA2 ', EA3' d '. advertisers AT, A2 ', A3' (Ak ') responsible for defining, for each advertiser respectively, data of any type comprising information to be displayed, profiles of targeted target persons and sets of relevance criteria (as presented herein). after according to an embodiment). In this case, the equipment EA1 ', EA2', EA3 'feeds the definition module MD, by own reception inputs not shown, to characterize the aforementioned groups. The definition module MD then provides the definitions of these groups to the calculation module MCL. Such an SS service server may in particular belong to an advertising agency or advertising broker managing advertising space.

The invention is described below in terms of a method for managing the display of information, which can be implemented in particular by means of the systems and devices described in FIG. -before. Thus, this method applies whether the display medium is: fixed, movable along a path or implanted in a public transport vehicle. Referring to Fig. 11, a series of steps constituting a display management method according to one embodiment of the invention is described.

In a main step 10, called correspondence, it begins by establishing matches between the information to be displayed and groups each defined by at least one objective or subjective profile characteristic. Said groups are defined during a characterization step to define these groups of target persons. During this characterization step (also under the reference 10), we define the sets of relevance criteria including profile characteristics, a minimum number of target persons to be reached, and a maximum budget for one ₍ given display). of relevance is then associated with information to be displayed Each set of relevance criteria and the information to be displayed are subject to specifications provided by an advertiser Ak '.

This main step 10 may optionally be followed by an auxiliary step 20 during which a display device (fixed, mobile or installed in a public transport vehicle SA) is downloaded locally to a management device D. sets of relevancy criteria defined by Ak 'advertisers before a posting session. This local download prevents the management device from requesting the downloading of this data (or limits the data exchanges) by the SS server via the network RM during the course of the following algorithm, which reduces its execution time and allows a resulting display faster.

In a main step 30, we start locally the algorithm to perform a display session.

In a main step 40, called localization, the presence of target persons is determined. If the support is fixed, the presence of the targets is determined in at least a first zone Z1 of predetermined geographical position, located in the vicinity of said fixed display medium SA object of the display session and in which said display medium is in visibility of said target persons. If the support is mobile, it determines the presence of the targets that may be present in a given time interval in at least a first zone Z1 of predetermined perimeter, attached to a portion AF, MA said display medium SA along said trajectory , located in the vicinity of the latter and wherein said display medium is in visibility of said target persons. If the support is installed in a public transport vehicle, the presence of the targets among the passengers, which are located near the display medium of the vehicle VT object of the display session, is determined. In all cases, these target persons are associated with profiles defined by objective and / or subjective profile characteristics used in the correspondence step 10.

In a main step 50, called storage, stores the profiles of the target persons that have been detected in the zone Z1.

In a main step 60, so-called calculation step, it is distributed in groups, each defined by at least one profile characteristic and used in the correspondence step 10, the target persons whose presence has been determined in the zone Z1 nearby. of the display medium SA (fixed support), respectively the determined target persons who are likely to be present in said first zone Z1 in said time interval (mobile support), and the target persons whose presence has been determined at the inside the VT vehicle near the SA display bracket (support in public transport vehicle). In this calculation step 60, the target groups whose presence has been determined can be divided into the different groups according to the sets of characteristics (s) of profile which were possibly defined by the advertisers Ak 'during the step of correspondence 10.

This last step 60 can be optionally completed by an auxiliary step 70, called selection, performed by software selection means for example not shown, during which one selects among the groups those for which the number of target persons is reached, ie the groups for which the criterion of relevance of the minimum number of target persons to be reached has been met.

Finally, in a main step 80, called display, it controls the display by the display medium SA at least one information that corresponds to the characteristic (s) of one of the groups chosen according to the number of target people it groups compared to those of other groups. The chosen group must necessarily include at least two target people.

During this display step 80, it may optionally be controlled to display the information associated with the selected group for which the advertiser Ak 'has defined the highest of the maximum budgets.

Four examples of sets of relevance criteria defined by four advertisers A1 'to A4' are described below. For example, a first AV advertiser, on the other hand, wants to display its advertisement if at least 25% of the people detected (and identified) in the display area in question meet the three profile characteristics "CSP +" (socio-professional category executive level). superior), "over 25" and "sports fan", and secondly, the advertiser is willing to pay 10 € for a duration of display of its advertising for three minutes.

For example, a second advertiser A2 ', on the other hand, wants to display its advertisement if at least 60% of the detected (and identified) people in the display area are men, and if at least 40% of the people detected (and identified) in the display area concerned are at least 50 years old, and secondly, this advertiser is willing to pay 12 € for a duration of advertising for three minutes.

For example, a third advertiser A3 ', on the other hand, wishes to display its advertisement if at least 65% of the people detected (and identified) in the display area concerned are women, and on the other hand, this advertiser is willing to pay € 5 for a duration of display of its advertising for three minutes.

For example, a fourth advertiser A4 ', on the other hand, wants to display its advertisement if at least 40% of the people detected (and identified) in the display area concerned are executives, and if at least 32% of the people detected (and identified) in the display area concerned are at least 50 years old, and on the other hand, the latter advertiser is willing to pay 6 € for a duration of display of its advertising for three minutes. If the criteria specified by advertisers {targeted population profile

+ minimum percentage of the population in the area} are satisfied only for AV and A2 ', it will then be ordered display poster associated with A2', the latter having proposed the highest budget sums for a same display duration.

Thus, it is remarkable that the process according to the invention:

- dynamically takes into account a population in a predetermined area,

- divides this population into groups defined by at least one profile characteristic,

- controls the display on a display medium corresponding to a selected group, the latter comprising at least two people.

This method makes it possible, according to an advantageous embodiment, to isolate the processing step on the profiles (collection of profiles and distribution in groups) and to entrust this step to an actor of the economic circuit which will have received authorization. , or at least, which collects from the outset profiles and has the capacity to provide figures not representative of the privacy of the target persons (ie proportions that represent each group detected in zone Z1). Even in this case, it is necessary to limit the chosen group to the number of two target persons. Indeed, it is necessary that the actor holder of the confidential information transmits only data from which it is impossible to go back to the target persons whose group corresponds to the information displayed. If zone Z1 has only one person, it can be expected to display only one poster that does not match his profile. For example, it may be possible to display a poster corresponding to a group for which a minimum quota has not yet been reached.
