Description: System and Method for Exchanging Business Cards during a Videoconference BACKGROUND OF THE INVENTION Field of the Invention The present invention relates to the field of personal computer (PC) conferencing. More specifically, the present invention relates to modeling participant behavior of traditional face-to-face conferences in PC conferences. Background Information As advances in telecommunication and computing technology continue to bring forth more powerful PC conferencing systems, both users and system integrators desire closer modeling of participant behaviors of traditional face-to-face conferences in PC conferences. One particular behavior of interest is the practice of conference participants exchanging business cards in face-to-face conferences. The business cards not only serve as vehicles of introduction, they also serve as information sources. It is not uncommon for conference participants to save the exchanged business cards and refer to them later on. The conference participants may refer to the saved business cards for a variety of reasons. Sometimes, the conference participants may be referring to the saved business cards simply to remind them of the persons they met, including the fellow participant's affiliations, titles, etc. Other times, the conference participants may be referring to the saved business cards to figure out the roles, the interests, etc. of the fellow participants in attending particular conferences or advocating particular points of views, through the affiliations, titles etc. information. Yet other times, the conference participants may be referring to the saved business cards as a resource for someone to whom they themselves can turn or refer colleagues, clients etc. to consult on certain subject matters. In sum, notwithstanding the limited amount of information typically contained in a business card, its utility is amazingly broad. In fact, it is a common practice for professionals in a variety of disciplines to routinely enter the information in business cards into their address databases for subsequent retrieval for the purposes described earlier, and /or for mailing of announcements, seasonal greeting cards etc. Thus, it is desirable to be able to model business card exchanges for conference participants of a PC conference. It is further desirable to be able to capture the information in the exchanged "business cards" for subsequent retrieval. As will be disclosed in more detail below, the method and apparatus of the present invention achieves these and other desirable results. SUMMARY OF THE INVENTION The conference manager and address service of a general purpose personal conference (GPPC) application are enhanced with a plurality of functions for setting up, exchanging, saving, retrieving, browsing, and re-sending "business cards" electronically, thereby modeling the business card exchange behavior of conference participants of face-to-face conferences. Under the present invention, the external manifestation of an electronic "business card" (hereinafter simply "bizcard") is a visual presentation of information commonly found on physical business cards in a format that resembles a physical business card. Preferably, the visual presentation also includes a picture of the person named. Internally, the information including the data necessary to render the picture are maintained in data structures, thereby allowing the information captured to be searchable for subsequent retrieval. The functions include a first function for automatically transmitting a user's bizcard whenever the user joins a PC conference, and a second function for receiving, displaying and saving received bizcards while the user is participating in a PC conference. In some embodiments, the functions further include a third function for setting up a bizcard for the user at system installation time, and subsequently editing the bizcard. While in other embodiments, the functions additionally /alternatively include a fourth function for retrieving and browsing the saved bizcards, and optionally re-sending the retrieved bizcards.

These and other related services are known in the art, and therefore will not be described in further detail. Figures 3a & 3b illustrate the external manifestation and internal representation of a bizcard of the present invention. As shown in Fig. 3a, the external manifestation is a visual representation 38 of information commonly found on physical business cards in a format that resembles a physical business card. These information include name 39a, title 39b, company 39c, division 39d, address 39e, phone numbers 39f etc. Preferably, the phone numbers 39f include all personal conferencing phone numbers /network addresses, in addition to conventional voice and facsimile phone numbers, and the phone numbers are scrollable 39h. Furthermore, the visual presentation 38 includes a picture 39g of the person named. Alternatively, a company logo may be included. As shown in Fig. 3b, internally, the information including the data necessary to render the picture 41g are maintained in data structures 40. Data structures 40 include data elements 41a - 41g necessary to store the captured information. Data necessary to render the picture 41g may be stored in any number of graphics format well known in the art. Referring now to Figures 4a - 4b, wherein the operational flow of one embodiment of the additional functions incorporated in conference manager 26 for setting up a user's bizcard 38 is shown. As shown in Fig. 4a, as part of the install process, a bizcard create /edit function is invoked, step 47. As shown in Fig. 4b, when invoked, the bizcard create/ edit function displays a first input window including instructions to the user, general navigational/ control commands, context specific commands, and input areas for accepting user inputs, step 48a. If the inputs are data entered or changes made, the bizcard create/edit function captures the data entered or changes made in temporary storage area, step 48c. On the other hand, if the user selects certain context specific commands, the bizcard create/edit function then performs the selected commands accordingly, step 48e. However, if the user selects a navigational command, such as going back one window or going forward to the next window, the bizcard create /edit function refreshes the display with the appropriate window, step 48g. Finally, if a cancellation control command is selected, the bizcard create/ edit function exits without saving the data entered or changes made first, whereas if a normal exit control command is selected, the bizcard create/edit function saves the data entered or changes made first before exiting, step 48i. Figures 5a - 5e illustrate one embodiment of the user interfaces employed by the bizcard create /edit function illustrated by Fig. 4a - 4b. As shown, under this embodiment, all windows 42a - 42e comprise instructions to the user 43a - 43e, navigation commands (Back, Next) 45a - 45b, normal/exceptional termination control commands (Cancel, Finish) 46a - 46b, data input areas 44a - 44e, and a visual representation of the bizcard 38a - 38e being set up. Additionally, a window may have window specific commands. For example, window 42b has exemplary window specific commands Snap, Browse and Paste 47a - 47c. Snap 47a causes a snapshot of the user to be taken using the video devices of the system, and the snapshot to be used as the picture to be incorporated in bizcard 38. Alternatively, Browse 47b is used to display and select an existing picture or logo (more specifically, a file containing the desired picture or logo), and Paste 47c is used to incorporate the selected picture or logo in bizcard 38. Referring now to Figures 6a - 6b, wherein the operational flow of one embodiment of the additional functions incorporated in conference manager 26 for exchanging bizcards 38 with other conference participants are shown. As illustrated in Fig. 6a, under this embodiment, as part of the response to a connect event, conference manager 26 automatically transmits the user's bizcard 38 to its counterpart in a point-to-point PC conference or to the MCU 16 in a multi-point PC conference, which in turn transmits the bizcard 38 to all other conference participants. As illustrated in Fig. 6b, conference manager 26 conditionally displays the received bizcard 38, depending on the user's display preference setting, steps 62-64. Additionally, conference manager 26 saves the received bizcard 38 in address service 30, step 66. Preferably, a new data structure 40 is created only if the received bizcard 38 is a new bizcard 38. For a previously saved bizcard 38, the newly received information are simply merged into the existing data structure 40. Additionally, for multi-point PC conferences, conference manager 26 further determines if the received bizcard 38 is from a "new" conference participant, i.e. someone who is in the process of joining the multi-point PC conference, step 68. (In other words, the received bizcard 38 is not a response to the bizcard 38 sent out by the user, while the user himself/ herself is joining the multi-point PC conference.) If the received bizcard 38 is from a "new" conference participant, conference manager 26 responds by transmitting his/her bizcard 38 to the "new" conference participant, step 70. Figures 7a - 7b illustrate the user interfaces employed by the additional functions illustrated by Fig. 6a - 6b. In particular, Fig. 7a illustrates the display of one conference participant's bizcard (Salvador) 38f at another conference participant's conference session window (Elliott) 50, when the two participants first joined together in conference. Fig. 7b illustrates the display of a "new" conference participant's bizcard (Skarbo) 38g at one of the existing conference participant's conference session window (Elliott) 50, when the "new" conference participant is joining a conference in progress (between Elliott and Salvador). As described earlier, bizcards 38f and 38g may be displayed automatically upon receipt, or bizcards 38f and 38g may be displayed upon request, using exemplary command button "?" 54, depending on the conference participant's preference setting. Preferably, notwithstanding an automatic display preference setting, exemplary command button "?" 54 may also be used to re-display the bizcard 38f or 38g of one of the conference participants, whenever the user is interested in doing so during the conference. Experience has shown a bizcard 38 similar to the ones illustrated 38a - 38g takes about 8 kbytes of data, with the picture consuming most of the 8 kbytes. Thus, their exchange among conference participants impose minimum burden on the data bandwidth of the conferencing system. Referring now to Figures 8a - 8b, wherein the operational flow of one embodiment of the additional functions incorporated in address service 30 for retrieving, browsing and re-sending bizcards 38 are shown. As illustrated in Fig. 8a, under this embodiment, responsive to invocation of the bizcard function of address service 30, address service 30 displays the "main" window to accept user selections, preferably including a defaulted address book and addressees in the address book, step 82. If the user selects one of the addressees displayed, address service 30 retrieves and displays the selected addressee's bizcard 38 (if it exists), thereby allowing the user to retrieve and browse a previously saved bizcard 38, step 86. On the other hand, if the user enters an addressee, address service 30 locates, scrolls the addressee display if necessary, and highlights the addressee located, step 90. Preferably, address service 30 responds on a key-stroke basis, i.e. matching addressee by the most significant characters. However, if the user enters the name of a new address book, address service 30 locates the address book and refreshes the addressees displayed, step 94. Finally, if a command or exit is selected, address service 30 performs the command or exits according, step 98. As shown in Fig. 8b, preferably address service 30 includes a "Send" command for re-sending retrieved bizcards 38. For this embodiment, responsive to the selection of the "Send" command, address service 30 displays a bizcard recipient selection window including a list of the current conference participants, step 100. Preferably, address service 30 echoes the addressee selections as they are being made, step 104. When the user is finished with making the addressee selection, by selecting an exemplary "Done" command button, address service 30 sends the retrieved bizcard 38 to all selected conference participants, step 108. The user may also cancel the selection and quit, by selecting an exemplary "Cancel" button. Figures 9a - 9b illustrate the user interfaces employed by the additional functions illustrated by Fig. 8a - 8b. As shown, the bizcard function of address service 30 includes an address book /addressee selection window 72. Address book /addressee selection window 72 includes an addressee display area 75 where the user can make his/her addressee selection. As described earlier, the selected addressee is highlighted, the selected addressee's saved bizcard 38h (if it exists) is displayed. Additionally, address book /addressee selection window 72 also includes a first input area 73 for locating an addressee, and a second input area 74 for switching address book. For the illustrated embodiment, address book/ addressee selection window 72 also include a "Send" command button 76 for re¬ sending the retrieved bizcard 38h to current conference participants. As shown in Fig. 9b, when the user selects the exemplary "Send" command, a bizcard recipient selection window 77 is displayed. For the illustrated embodiment, bizcard recipient selection window 77 includes current conference participant display area 79 where the user can make his/her bizcard recipient selection(s). Additionally, bizcard recipient selection window 77 includes selected conference participant display area 78 for echoing the user's selection(s). Lastly, bizcard recipient selection window 77 includes an exemplary "Done" command 80 for ending the selection and causing the retrieved bizcard 38h to be re-sent to the selected conference participants, and an exemplary "Cancel" command 81 for canceling any selection made and exiting without having the retrieved bizcard 38h re-sent. Thus, a method and apparatus for modeling business card exchanges in a point-to-point or a multi-point personal computer conference has been described. While the method and apparatus of the present invention has been described in terms of the above illustrated embodiments, those skilled in the art will recognize that the invention is not limited to the embodiments described. The present invention can be practiced with modification and alteration within the spirit and scope of the appended claims. The description is thus to be regarded as illustrative instead of restrictive on the present invention.
