5 Such bio-mechanical information/data may be transmitted to the recording or storage means 13 by an electronic means, har~
wiring or other communication means, either at the same time, as the c~ptured Yisual signals relating to scanned images of the person being viewed or at a different time. In the 10 embodiment illustrated, bio-mechanical information may be captured using a weight sensing pad or pads 14 which will sense weight transference during the swing.
The means used to collect and transmit such bio-mechanica1 in~ormation/data, is at all times non- restrictive in its overail performance, so as to allow the pupil being analyzed to achieve normal free flowing movement without restriction. One such moans may take the form of mechanical devicc/s affixed1 or attached, to the person or golf club moved by the person so as to show data suoh as prossures transferred 20 through thc arms or hands, proper releasing techniques, velocities achieved 9tc. Alternatively or additionally, sensing devices maybe positioned alongside, below or above the person whose image is being captured. Such sensing devices as above may comprise weight or load sensitive pads, monitors 25 electronic light beaming device or the like. ~io-mechanical, signals may also ~e obtained by various scanning, editing and digital techniques, used wi~hin a remote computer database as described further below, once the signal has been received by the ramote database, to determine also the many characteristics 30 of the person being studied.
The image capturing device 11 is preferably ~f portable construction, and of high recording quality, so as to scan, receive and store images and information/ data, in broadcast quality. These visual or information signals are converted by 35 sensors or the like, into electrical charge patterns etc, which are read out or scanned to produce, digital electronic signals representative thereof, from electrical or light signals, .

For initially captur;ng the necessary signals for 5 analysis, more than one image capturing d0vice 11 may be used, so as to shannel information regarding various visu~l details, informat;on/data or the like, to one recording or storage medium. In this regard various switching techniques may a7so be used to switch between selected image capturing d~vices 11.
The signal storage or recordin~ means may take ~he form of Magnetic Tape/Di~k, Laser Based or Optical Video Disk, Magneto-Optic Di~k, Magnetic-Laser-Optical Disk or other storage medium. Alternatively digitised signals representative of the scanned images or bio mechanical and information data 15 may be also transferred or stored onto a computer memory chip or the like, held within the camera ~ramswork.
The apparatus 10 also includes an audio/visual signal transceiver 14 adapted to receive and transmit audio/visual signals and other information signals in the manner described 20 below.
The imag~ capturing device 11 referred to above in one form is a unit discrete from the audio/visual signal transceiver 14 and adapted to be connected thereto or the two maybe one and the same, so that the image capturing device 11 25 also incorporates a unit for transmission and reception of signals to and from remote databasesO
The audio/visual signal transceiver 14 may take the form of a portable signal unit or a personal computer (PC), which can convert, compress or suitably accept, a down loading 30 of captured signals, stored within the storage means 13 of the portable camera unit and then reform, record or store such signals in a suitable digital state for later transmission over a communications network 15. The communication network 15 may comprise the general switched telephone network, satellite links, television quali~y cable links or the like over which the signals representative of the persons movement together with bio-mechanical information where stored are directed as .

electrical or light signals to a remote computer 16 for st~rage in a computer database 17 for later analysis against selected preferred signals also stored in a database o~ the computer or a further co~puter. As is conventional a modem or other 5 similar signal conversion devic~ may be associated with the computer 16 to receive the transmitter signals and convert those signals into a suitable form for reading by the computer 16. The modem or other similar signal conversion device may also be employed for transmission of signals from the computer 16 as described further below.
Initial capturing of audio, visual and data signal information, may also be undertaken using the audio visual signal transceiver 14 ~if not a personal computer~ to which a video camera 12 may be directly connected so ~s to enable 15 signals captured by ~he camera 12 to be recorded directly onto suitable storage medium held within the transceiver 14. The transceiver 14 is then able to transmit these captured signals to remote locations1 when directly connected to the communications network described above. Thus a single unit 20 may perform all functions of recording, transmitting and receiving audio, visual and data signal information. The transceiver 14 for this purpose may include dual signal storage facilities, to achieve the above functions, however the transceiver 14 may also be constructed so as to enable all 2~ functions of recording and playback in each mode within a single signal storage device.
This transceiver 14 is software and hardware programmed and may offer some of the following features:

As stated above, the computer 16 is arranged normally 15 at a ~emote location from the audio/visual transceiver 14 and includes a database 17 which stores selected prerecorded video signals in digita1 form which in the case of golf swings may include a selection of sw;ngs showing the movement of different golf professionals which are reqùired to be emùlated. As the 20 computer 16 and image capturing device 11 are not physically affixed or attached together, the computer 16 and database 17 may be of a sufficient size and capacity to enable the desired functions to be achieved at one and the same location.
The computer 16 may be at many remote loca~ions and 25 holds within its database the following prerecorded information in digital form, which provide a basis for forming the regenerated audio visual signals.
1) A digitised audio visual library of selected coaches, advissrs professional or mechanisms (such as a golf simulation 30 machine) movements, techniques, steps or procedures, that have been previously analysed, recorded and reformed into suitabl~

For this purpose, the computer is softwar~
and/or hardware programmed to compare the respective swings of 15 the person being analy~ed and the selected preferred swing with adjustments made such as for size of person, speed of swing and other parameters to allow a correct comparison. The differences between the swings are measured by sampling or other techniquas and this difference added or subtracted from 20 a persons recorded swing and new visual images generated on this basis which emulates the preferred movements.
The computer 16 may also include a means for adding dialogue to the regenerated audio visual signal recordings, so that the viewer can receive personalized instruction or advice 25 from afar, similar to having private instruction or personal consultation.
The computer 16 may further include a means for converting received signals, if needed, in one broadcasting mode, into those of another countries i.e. PAL-NTSC-SECAM etc.
30 To accomplish this within the computer, a Standards Converter or the like may be used, using Optical Scan or Digital Standards features or the like.

(b) The amount of analysis and regeneration timerea,uired, for each and every presentation, such as with the showing of audio visual faults, bio mechanical/characterizeddatagraphs,dialogue and broadcasting changes etc.
The computer 16 is software and hardware programmed, to accept digitised signals transmitted to it, from remota locations, associated with the audio visual transceiver 14, so as to personally relate in the final regeneration and editing 10 phases to the viewer, this being performed by, using various digital editing techniques and procedures as ~escribed below.
The audio visual presentation generated by the computer 16 can take the form of split-screening tgenerating new visual images of the preferred technique displayed along side the 16 present technique), superimposing (where the preferred technique is superimposed over the present technique) or other display. Graphics and charts etc, for bio-mechanical/
information displays, so that the viewer can clearly see those changes that are required or need to be performed, to develop 20 or pursue the preferred movement, procedure or proposal are also displayed. These superimposing effects or the like, may take the form of stick figures, detailed drawings etc, to normal human or visual appearances, so as to show the viewer any variances between his stroke and the preferred stroke. For 25 ease of edit;ng the subject material within this computer database, a time code or the like, maybe also burnt into the original recorded signal, so as to make final editing much more eff;cien~ with~n the remote database. This procedure may also be linked with an edit controller or the like, within the 30 computer 16, which locks the two signals electronically together during edits.
To personalize the regenerated signal, dialogue is also added when required, so that the selQcted instructor or adviser may relate to the viewer/pupil more personally, than with other 35 audio visual presentations. Part of this personalizing effect is initially accomplished in the original transmission phase, by the name, spoken language, broadcasting mode or location .. , : ~, . ; .. - ' WO 92/21412 PCI/AUg2/00253 statistics etc of the final viewer being captured, within this database, to which an addition of dialogue can also be added when required, in the regeneration signal phase, showing those changes they need to perform or consider, to obtain the 5 preferred movement, thus totally personalizing the new regenerated signal to the viewer.
For this purpose such dialogue, may only take the form of a brief statement, so as to make the viewer fully aware of those changes that are required, or need their considaration, 10 to perfect the movement, procedure or development etc.
The means for adding such dialogue may take the form of a voice energy monitor or the like, contained within the computer, which on analysis scans a memory bank of learned words or phrases to find suitable terms, to bring attention to 15 these problem areas or matters needing their attention.
Dialogue may also be added relating to recommendations for the viewers consideration in regards to, suitability of equipment being used to perform the desired movements and techniques.
To increase acceptance as a true teaching aid, scientific data, which in many applications coul~ only be assumed before, such as with personalized coaching, may be presented to a viewer, when needed, in the form of graphs, charts, or the like, set either above, below, alongside or 25 within the total regenerated video signal recording. This information is gathered from their received signals, being matched to, their preferred established signals contained within the database 17 so that the person/pupil can clearly see, those bio mechanical d;fferences that exist between, their 30 current procedures/techniques and that of their selected coaches/professionals procedures/techniques.
Once the new audio visual signal is regenerated ~he signal is then retransmitted back by the computer 16 and via a modem or the like and the communications network 15 to 35 the remote sender /agents transceiver 14. This procedure maybe performed, from within the computer 16 itself, using various digital, compression and sampling techniq~es, or it can be . , , - .

On receipt at the remote pupils/agents receiving location, the regenerated signal may already be in sui~able 5 form, for direct saving on suitable storage means such as video tape, disk or the like which enables home viewing such as by means for a video cassette player and playback through a monitor 18. If not in a suitable form for direct saving, the si gnal may be reformed for storage as above on s~orage means 10 which permi~s home viewing other than through a computer monitor by the use of either the receiving audio visual transceiver, or by other suitable conventional means, offering various slowing down or speedin~ up signal procadures. If desired the regenerated aud~o/visual signal may be stored on 15 the original stora~e means eg. video tape containing the players current movemen~s or techniques or stored on a new storage means.
In the e~bodiment described and shown, the image capturing device 11 stores the cap~ured images on a video 20 cassette 19 of known form and the regenerated images are stored on the sam~ cassette 19 or alternatively an additional cassette The regenerated image in this embodiment is in the form of a stick figure 20 which is superimposed on the true visual image 21 of the players swing or movement and which indicates to the player the angles and positions which he must adopt to emulate the swing.
To add further to this advanced audio visual teaching aids value, as a complete instructional system, compared to other audio visual presentations, previously recorded instructional material, of a non-personalized nature, may also be added, to the ~inal home storage presentat~on means such as a video cassette. Thus this regenerated transmitted signal of the pupil~s ~udio visual presentation and data pertaining to movements, maybe then simply added to the prerecorded material 35 already held at the senders/agents remote location. In this format the single recording may then show (a) an initial complete recorded procedure of instruction, as currently ,., : - .,.. : ........................ . , ........... , .

The above embodimant has been described with reference to a golf swing movement, however, as previously s~ated the invention may readily applied where other movements are required to be emulated. Such movement may comprise movements 5 of persons or movernents of objects or mechanisms of which emulation is required.
In a further form the invention may be applied to the property field to enable professional assessments and presentations of designs for ~uture development proposals or 10 the like. In this form visual images and da~a relating to signals of a particular area of ground are captured using remote sensing techniques. For this purpose a camera and remote sensing device may be fixed to the underside of an aircraft so as to capture and record geometrical or statistical 1~ information of the earth or objects featured beneath.
Geographical data achieved through using this remote s~nsing as above may be computer coded or digitised using video cameras, array scanners, laser beam, microwave or other means.
Information regarding the geographical area being 20 scanned is then transmitted as before using a transceiver to a remote computer containing a database of prestored expert i nformati on on attributes required of a particular area of land. Thus where the best standard of golf course is required to be laid out upon a specific parcel of land the data base may include a library of selected hole layouts from different courses. The computer which is software programmed may then select preferred hole layouts to match to the area of land of which geographical features has been scanned and recorded.
Alternatively, the computer may itself design the appropriate 30 hole layouts to best fit the area of land and proposed development. The compùter database may additionally include feasibility study means for determining and displaying measurements, costings and other procedures required to achieve the end result. The computer may further be programmed to take into account residential housing around the course and the location of same, so as to maximize view of the course etc.
As before, dialogue may be added to the regenerated . . - - . ~ ,:

The present invention may also be applied to enable a particular object to be analysed against prestored data relating to a currently known object. In this embodiment and as before an object is scanned so that its characteristics may be determined. Scanning is carried out to obtain ~he optica1 photometric characteristics of the object using imaging and non-imaging sensor systems. As before the data obtained is 10 stored and then transmitted to a remote location for analysis in a computer with the corresponding da~a of a preferred object whose data information is captured in a data base. After comparison and adding, where appropriate, suitable dialogue from say an expert in that field, a regenerated signal is 1~ formed and transmitted back to the sender so that the sender has an expert assessment of the differences between the respective objects. A particular application in this embodiment is for component parts as used in an assembly. The data information obtained relating to that part may be compared 20 to a perfect component part whose data is stored at the remote location so that the differences may be assessed. This embodiment may also be employed for detecting for example faults in a particular component part.
It will be apparent that the latter embodiment may be 25 applied to any suitable targets of which analysis is required.
The present invention thus provides a method and means for expertly teaching or instructing procedures, strateyies, assessments or perceptions in audio visual form to enable a viewer to more closely emulate calculate or develop techniques 30 suitable to their various applications.
Whilst the above has bèen given by way of illustrative embodiment of the invention, all such modifications and variations thereto as would be apparent to persons skilled in the art are deemed to fall within the broad scope and ambit of 35 the invention as herein defined by the appended claims.

In a further form the invention may be applied to the property field to enable professional assessments and presentations of designs for ~uture development proposals or 10 the like. In this form visual images and da~a relating to signals of a particular area of ground are captured using remote sensing techniques. For this purpose a camera and remote sensing device may be fixed to the underside of an aircraft so as to capture and record geometrical or statistical 1~ information of the earth or objects featured beneath.
Geographical data achieved through using this remote s~nsing as above may be computer coded or digitised using video cameras, array scanners, laser beam, microwave or other means.
Information regarding the geographical area being 20 scanned is then transmitted as before using a transceiver to a remote computer containing a database of prestored expert i nformati on on attributes required of a particular area of land. Thus where the best standard of golf course is required to be laid out upon a specific parcel of land the data base may include a library of selected hole layouts from different courses. The computer which is software programmed may then select preferred hole layouts to match to the area of land of which geographical features has been scanned and recorded.
Alternatively, the computer may itself design the appropriate 30 hole layouts to best fit the area of land and proposed development. The compùter database may additionally include feasibility study means for determining and displaying measurements, costings and other procedures required to achieve the end result. The computer may further be programmed to take into account residential housing around the course and the location of same, so as to maximize view of the course etc.
As before, dialogue may be added to the regenerated . . - - . ~ ,:

The present invention may also be applied to enable a particular object to be analysed against prestored data relating to a currently known object. In this embodiment and as before an object is scanned so that its characteristics may be determined. Scanning is carried out to obtain ~he optica1 photometric characteristics of the object using imaging and non-imaging sensor systems. As before the data obtained is 10 stored and then transmitted to a remote location for analysis in a computer with the corresponding da~a of a preferred object whose data information is captured in a data base. After comparison and adding, where appropriate, suitable dialogue from say an expert in that field, a regenerated signal is 1~ formed and transmitted back to the sender so that the sender has an expert assessment of the differences between the respective objects. A particular application in this embodiment is for component parts as used in an assembly. The data information obtained relating to that part may be compared 20 to a perfect component part whose data is stored at the remote location so that the differences may be assessed. This embodiment may also be employed for detecting for example faults in a particular component part.
It will be apparent that the latter embodiment may be 25 applied to any suitable targets of which analysis is required.
The present invention thus provides a method and means for expertly teaching or instructing procedures, strateyies, assessments or perceptions in audio visual form to enable a viewer to more closely emulate calculate or develop techniques 30 suitable to their various applications.
