Description

Interactive Electronic Commerce and Message Interchange System Featuring Delivery of Messages Tailored to Individual Users

CROSS-REFERENCE TO RELATED APPLICATION

The present application claims priority from U.S. provisional patent application Ser. No. 60/395,579 filed July 12, 2002 and entitled "Interactive Electronic Commerce and Data Interchange System Featuring Universal Digital Assistant," and U.S. provisional patent application Ser. No. 60/395,578 filed July 12, 2002 and entitled "Interactive System Allowing for Mass Media Delivery of Advertising, Promotion, Electronic Commerce and Data Interchange Messages to be Multiplexed and/or Tailored to Individual User Characteristics . "

FIELD OF THE INVENTION The present invention relates to electronic commerce and, more particularly, to methods, apparatuses and systems facilitating and/or enabling an interactive electronic commerce system that delivers advertising, and other electronic commerce and data interchange messages adapted to individual user characteristics.

BACKGROUND OF THE INVENTION

Commercial network television has been recognized as a powerful and efficient medium for broadcasting advertising messages to a large, widely disbursed audience. One major drawback of television advertising, however, is network television's ability to do nothing more than deliver advertising messages to a large and relatively undifferentiated audience. Network television, for example, can not by itself provide coupons to, or otherwise interact with, interested viewers.

Traditionally, discounts and other such benefits, e.g. free samples and the like, have been provided or authorized by way of hard copy printing of coupons in newspapers, magazines, mailer brochures and the like. While such printed authorizations, e.g. coupons have been effective and extensively used, they have presented certain problems. Printed coupons require a substantial amount of time to prepare and deliver to the potential user. For example, one may need three months or more to print and deliver such printed coupons. The need for the promotion may change during that time. Moreover, such coupons are largely ignored by a majority of consumers who are unwilling to take the time to retain the coupon for later use.

Mass media communications, including advertising, promotion, and other means of information and data distribution dehvered to the public by various mass media systems such as television, Internet, radio, newspapers, magazines and other printed material, wireless and satellite, have not been able to create one-to-one, micro-matrixed or matrixed multiplexed messages or data packages tailored to individual users. Prior to the invention described herein there has been no mass media system that, in response to a mass media message, allows for the delivery of customized or tailored messages to individual users concurrently or sequentially with the mass media message. There is demonstrable, pent- up demand from consumers, financial services, merchants, the media, advertisers, cellular services, device manufacturers, data service providers and others seeking means for methods, apparatuses and systems allowing for efficient and secure delivery of advertising messages tailored to individual users. A need in the art also exists for methods, apparatuses and systems that leverage the ability of television broadcasts to reach large audiences with an interactive system that delivers messages, such as coupons, product offers and the Hke, to end users. Embodiments of the present invention substantially fulfill these needs.

SUMMARY OF THE INVENTION The present invention provides methods, apparatuses and systems enabling an interactive electronic commerce and data interchange system that delivers advertising, content and all manner of ecommerce and data interchange messages tailored to individual users. The present invention provides methods, apparatuses and systems enabling an interactive electronic commerce system enabling the targeted exchange of tailored messages with interested users presented with message codes in conventional media, such as television, radio, and printed publications. The present invention allows for the targeted dissemination of tailored information, such as advertising, promotions, sales announcements, coupons, and the like. In one embodiment, the a Universal Digital Assistant (UDA) operates in connection with a remote server having access to the individual users demographic, psychographic, preference, contact and other personal information and delivering advertising messages based on data associated with individual users. The universal digital assistant, in one embodiment, is also operative to facilitate financial transactions and data interchange, as well as the dissemination, management and exchange of commercial information, data and other information, such as advertising, promotions, sales announcements, product information, financial information, personal information including licenses, memberships, government programs and the like.

The present invention, in one embodiment, provides an end-to-end ecommerce solution that transforms the cell phone/PDA into a Universal Digital Assistant (UDA) which can receive customized advertising messages including advertising based on message identifiers encoded into advertising and content from television, Internet, wireless, radio, satellite and print media.

According to one embodiment, a user can elect to save the advertising message for possible later use or inspection, either by storing it locally on universal digital assistant 90 or remotely in association with his or her user account maintained by UDA apphcation site 50. A. Capturing Message Codes with Universal Digital Assistant

As discussed herein, universal digital assistant 90 is operative to detect and/or receive message codes via one to a plurality of code capture technologies. For example, universal digital assistant 90 can be configured to capture codes from televisions or other display devices, print media, or wireless transmissions. In its most basic form, message codes can be captured manually by allowing a user to input a message code directly using the user interface provided by universal digital assistant 90, such as a touch sensitive screen, numeric key pad or voice activated and voice-recognition-based user interface.

A.l. Manual Message Code Capture

In one embodiment, users use the keypad of a cell phone (or other available interface — e.g., a touch sensitive screen, etc.) to enter message codes and transmit them to UDA apphcation site 50, as more fully described below. In the manual case, message codes are preferably alpha-numeric strings made perceptible to users in various media, such as television, print and radio media. For example, during a radio broadcast, a message code may be provided during an advertisement. In print media, the message code may be included on various pages of a magazine or newspaper for example. Communication of captured message codes to UDA apphcation site 50 can be accomplished using circuit- switched (hke a normal cell phone call), and packet-switched (similar to a text message) methodologies. The circuit switched option is provided since every cell phone in deployment today supports it. Every form of mass media is supported via keypad entry including message codes appearing on television, Internet, radio and print media.

A.l.a. Circuit-Switched Keypad Interface The circuit-switched keypad interface option is available to all handset terminals, both analog and digital. The only requirements are that the terminal support in-band DTMF signaling. In this scenario the user simply types in the phone number corresponding to UDA application site 50 and hits the "send" key just as making a normal call. Interface server 31 of UDA apphcation site 50 answers the call and an automatic message prompts the user to enter the message code on the keypad. In this use case, the user hits the "End" key and the transaction is complete. By storing the advertisement processing center's phone number in a quick dial location only the quick dial key needs to be pressed to initiate the call followed by entering the advertisement redemption number on the keypad.

As Figure 1 illustrates, UDA apphcation site 50, in one embodiment, includes interface server operably connected to telecommunications network 35 to allow users to UDA apphcation site 50 using a voice-based telephone network device, such as POTS telephone or wireless phone 90. Specifically, interface server 31 provides call process flow functionahty, pre-recorded voice-based scripts, and a voice-based and/or DTMF-based interface allowing users, using touch keys on telephones and/or voice commands, to enter message codes observed in various media. In one embodiment, interface server 31 includes speech recognition functionahty operative to translate voice signal data into text data suitable for further processing. A variety of speech recognition systems are known, all of which can be apphed to the present invention. Interface server 31 may also be operative to transfer users to customer service call centers upon a request from a user, or the detection of an error or condition requiring human intervention.

A.l.b. Packet-Switched Keypad Interface The packet-switched interface option is available to all cell phones that support simple text messaging. Typically all digital phones support simple text messaging. In this scenario the user simply types in the advertisement processing center's phone number for the text message destination and then enters the message code on the keypad into the body of the text message. Pressing the "Send" key automatically sends the text message to UDA apphcation site 50. Utilizing text messaging also allows UDA application site 50, in one embodiment, to push the promotional message corresponding to the message code back to the user's phone. A Figure 3 illustrates, with customization of the text message editor software in the phone, a custom "message code text message editor" can be created which already knows the advertisement processing center's phone number. In such as embodiment, the user need only enter the message code and hit "send."

A.l.c. Voice Recognition Interface In one embodiment, message code entry takes advantage of voice recognition technology already heavily deployed in cell phone handset terminals today. One such embodiment leverages the same customized "message code text message editor" described above with voice recognition technology to allow users to enter the message code using simple voice commands. Additionally, users can access the "message code text message editor" by simply saying the key work "message code" instead of navigating the menu system of the cell phone or other device. In this case the user only says one word "message code" to invoke the message code text message editor, speak the message code and the word "send" to transmit the text message to UDA apphcation site 50.

A.2. Video/Television Signals

In one embodiment, universal digital assistant 90 is operative to capture message codes embedded or otherwise transmitted in connection with a television signal and displayed on a display device 95, such as a television or computer monitor. For example, universal digital assistant 90 may include the code capture technologies whereby a user, using universal digital assistant 90, aims the device at a television or computer display and captures an image of the television or other video display. The captured image or a portion thereof is then processed to locate a message code and translate the message code to yield a message code identification. In one embodiment, universal digital assistant 90 includes digital camera technology to capture an image and image processing functionality to locate and identify a message code, if any, in the captured image. In one embodiment, message codes may be displayed on the television or other display as plain text codes at a predetermined location on the display. In such an embodiment, the image processing functionahty of the universal digital assistant 90 is operative to locate the message code and use text recognition functionahty to identify the message code. In another embodiment, message codes are displayed as graphical symbols which the universal digital assistant processes to identify message codes. In one embodiment, universal digital assistant emits a beam of light (e.g., Class II Laser Pointer 635nm <1.0mW safe per FDA assuming 0.25 second blink reflex) that helps the user to aim the image capture device at the television or video display. In one embodiment, universal digital assistant 90 captures the image from a television or computer display and transmits it to a remote processor, such as UDA application site 50, for analysis and resolution of a message code. In one such embodiment, the captured image is transmitted to UDA application site as an MMS message. In another embodiment, the incoming message code can be embedded in the audio track of the television signal. The embedded message code can be subliminal (not perceptible to the user) or overt.

According to one embodiment of the present invention, the message codes are presented as overt checkerboard-hke designs which are captured with a digital camera. In one embodiment, the digital camera is integrated into the UDA, such as digital cameras embedded in cell phones. Some features of the checkerboard are fixed to allow easy alignment to the data transfer part of the image. The left column is all black. The next two columns work as a pair in some cases, such as at the top and bottom where they are all black. At multiple other places in this pair of columns, 4 blocks (where the top two are white and the bottom two are black) work to define a set of white to black transitions while scanning down the image. The black edge and the transitions are picked out of the larger image. Between subsequent transition blocks, data is passed in one row of bits, black or white or both. Other images are contemplated to allow data transfer of the relatively small quantity of bits needed to identify information including the television broadcaster or the content being broadcast. Of course, any suitable graphical technique to express message codes can be used.

In another embodiment, the present invention may incorporate the code capture technologies disclosed in U.S. 5,594,493 incorporated by reference herein, which teaches methods and apparatuses that capture embedded codes expressed in modulated luminance levels in a television signal. In addition, universal digital assistant may employ the code capture technologies disclosed in U.S. Patent Nos. 3,848,082, 4,807,031 and 5,633,766, incorporated by reference herein, which teach the encoding of data in the effective viewing area of a video signal.

In one embodiment, the message code can be an arbitrary alphanumeric string that is associated with an advertising or promotional message. In another embodiment, the message code can identify the television station to which the television is tuned (such as station call letters, station ID, etc.). In such an embodiment, an advertisement or promotional message can be identified by reference to the station ID and the time the message code was captured. In one embodiment, scanning this information against a station log, UDA apphcation site 50 can resolve the advertising or other content the user was watching and return an advertising or promotional message associated with the broadcast advertising or other content. In another embodiment, universal digital assistant 90 operates in connection with a television set-top box to receive message codes. According to one embodiment, the digital set-top box is configured to receive message codes transmitted using any suitable means. Universal digital assistant 90 can then receive the message codes from the digital set-top box via wireless transmission, such as Bluetooth, 802.11b, and Wi-Fi. This embodiment bypasses the need for over the screen message code transmission. In one embodiment, at the time a broadcast displays an offer of interest, user action will trigger UDA 90 to contact the set-top box. The set-top box responds with the message code and/or details of the offer. UDA 90 can then transmit the code as described above. Alternatively, the set-top box may pass the query to UDA apphcation site 50, ehminating the need for a wide area network connection between the universal digital assistant 90 and UDA apphcation site 50.

A.3. Print Media In one embodiment, universal digital assistant 90 is operative to capture message codes from print media and the like. In one embodiment, universal digital assistant 90 includes a digital camera and image processing functionality that is operative to extract at least one message code from a captured image of a print advertisement. In another embodiment, universal digital assistant 90 includes bar code scanning functionahty operative to read a bar code expressing a message code in the print media.

A.4. Wireless Transmissions

As discussed above, universal digital assistant may be configured to receive message codes transmitted by devices within the immediate vicinity of the universal digital assistant. For example, universal digital assistant may receive message codes from a transponder transmitting message codes using technology including infrared, Bluetooth, IEEE 802.11, Wi-Fi, or short burst Ethernet technologies. Such transponders may be located at a variety of physical locations, such as a point of sale location, a movie theater, a mall, or a restaurant.

B. Retrieving Tailored Electronic Commerce and Data Interchange Messages As discussed above, after a message code is captured, universal digital assistant 90 is configured to transmit the message code to UDA apphcation site 50 which resolves the message code and returns an advertising message tailored to at least one characteristic associated with the user. Figure 3 illustrates a process flow for delivering an advertising message tailored to at least one characteristic of the user. In one embodiment, apphcation server 52 receives a request including the message code and a user account identification corresponding to the user (step 202). In one embodiment, UDA apphcation site 50 includes Automatic Number Identification (ANI) functionahty allowing identification of telephone numbers associated with incoming calls. Such telephone numbers are used in one embodiment to identify users and retrieve user account information from the user account database. As discussed above, in one embodiment, apphcation server 52, resolves the message code and the time of code capture against a station log to identify the advertising or other content broadcast when the code was captured. In other embodiments, the message code is an arbitrary identifier that maps directly to an advertising message/dehvery rules set. Apphcation server 52 accesses advertising message database 56 to retrieve advertising message delivery rules, if any, associated with the message code (step 204). Apphcation server 52 then processes available user account data corresponding to the user's account against the delivery rules to identify an advertising message associated with the message code (step 206). If an advertising message is found, application server 52 then transmits the advertising message to universal digital assistant 90 (step 208), and/or stores the message in association with the user's account for subsequent access. Application server 52 can also perform other functions, such as logging the message code and/or advertising message in association with the user's account. Apphcation server 52 may also log the message code to track usage of the system to allow for billing of the service. For example, an advertiser may be charged a fee for each advertising message transmitted to a universal digital assistant. In addition, UDA application site 50, in one embodiment, is configured to transmit usage/activity reports to advertising system detailing the activity associated with advertising messages, such as reports correlating the demographics associated with users and the advertising messages viewed by them.

As discussed above, a user may perform a variety of actions with respect to the advertising message. The user may view the advertising message and simply discard it. Alternatively, the user may save the advertising message by storing it locally, or remotely in association with the user's account maintained by UDA apphcation site 50. For example, the advertising message may be an electronic coupon, which the user may store for later redemption at a point of sale location or by accessing merchant system 50 using client 5 computer 64.

The message transmitted by UDA apphcation site 50 may take many forms. For example, the message may be transmitted as an email to a user's email account. Alternatively, the message may be transmitted as an SMS message to the user's cell phone. In one embodiment, the message may be transmitted using the Multimedia Messaging

10 Service (MMS) to transmit a digital image of a coupon for example including a UPC code expressed as a bar code (see Figure 4). This coupon, in one embodiment, can be redeemed by a user by displaying the coupon on a display 104 of universal digital assistant 90 and having a bar code scanner at a point of sale terminal pass over the display 104. As one skilled in the art will recognize, this embodiment allows users to gather coupons and

15 redeem them without having to collect and retain physical coupon shps and the like. In addition, since the electronic coupons are contained in the user's cell phone, for example, the user is more apt to use the coupons and purchase the promoted product or service. As discussed above, a user may perform a variety of actions with respect to the promotional message. The user may view the promotional message and simply discard it.

20 Alternatively, the user may save the promotional message by storing it locally, or remotely in association with the user's account maintained by UDA apphcation site 50. For example, the promotional message may be an electronic coupon, which the user may store for later redemption at a point of sale location or by accessing merchant system 50 using chent computer 64, or directly at a point of sale location using universal digital assistant

25 90.

In one embodiment, universal digital assistant 90 allows the user to manage electronic coupons received by the user. In one embodiment, navigation through existing coupons will be facilitated by standard PDA user interface capabilities: 1) scan categories then select one to view, scan coupons in the category; 2) delete a coupon or mark it for a

30 special category: shopping hst; 3) view hst of coupons to expire in 2 weeks; 4) At a point of sale location, provide easy IrDA access to list of UPC codes for stored coupons. In one embodiment, once a coupon has been redeemed, it is marked for deletion. Coupons noted to have past their "good thru" date are also marked for deletion. In one embodiment, universal digital assistant 90 requires the user to exphcitly invoke the batch deletion. In another embodiment, universal digital assistant 90 automatically performs such batch deletions.

C. Conducting Financial Transactions

As discussed above, universal digital assistant 90 may also be configured to facilitate financial transactions. For example, and in one embodiment, universal digital assistant 90 may securely store a user's financial account information, such as credit or debit card account numbers, checking account identifications and the like. Using a wireless transmission protocol, such as IrDa or Bluetooth, universal digital assistant 90 can transmit account information directly to a transaction processing device at a point of sale location. The transaction processing device can authorize or otherwise process the transaction in a conventional manner. In one embodiment, UDA apphcation site 50 can be involved in such point of sale transactions. For example, universal digital assistant 90 may transmit information related to the point of sale transaction to be logged in a financial transaction history maintained in association with the user's account. In addition, UDA application site 50 may be invoked to transmit a previously stored electronic coupon to universal digital assistant 90 to allow the user to redeem it at the point of sale location. In another embodiment, the user's financial account information may be maintained at UDA apphcation site 50. In one form, a transaction at a point of sale location can be completed where the user activates universal digital assistant 90 to request the user account information from UDA apphcation site 50. After it receives the user account information, universal digital assistant 90 transmits the account information to the transaction processing device as described above.

Furthermore, universal digital assistant 90, as a WAP-enabled device for example, can be used to conduct transactions with merchant system 50 over computer network 40. For example, universal digital assistant 90 may be configured to include electronic wallet functionahty (operating independently or in connection with UDA apphcation site 50) operative to facilitate on-hne financial transactions with merchant system 50 over computer network 40. Lastly, the present invention has been described with reference to specific embodiments. Other embodiments of the present invention will be apparent to one of ordinary skill in the art. It is, therefore, intended that the scope of the invention not be limited to the embodiments described above.
