Appeal No. 2004-0820 Application No. 09/317,312 Page 8 systems have a single pointer icon that is shared among the conference participants. When one user is finished using the pointer, the user must relinquish control. Pointer control is then acquired by another user, or reacquired by the previous user (col. 1, lines 52-60). All conference users can have pointer icons that are simultaneously active. However, it can be confusing if there are many participants and they all try to use their pointers simultaneously, resulting in a crowded work area (col. 2, lines 1-10). From this background, Glaser asserts that there is a need for a conference support system that permits each one of multiple workstation users to control pointers during a conference (col. 2, lines 13-18). In the Summary of the Invention, Glaser discloses that the system uses multiple user terminals, which includes a display having a common working area. Each user has a pointer icon that: can be used across all of the display screens; provides a representation of all conference participants, and displays a line from the pointer icon to the representation of the user (col. 2, lines 21-31). In one aspect of the invention, each user controls a pointer icon. The user's pointer icon and the line connecting the representation of the user with the user's pointer icon is displayed on the screens of the other participants if the user has taken a specific action,Page: Previous 1 2 3 4 5 6 7 8 9 10 11 12 13 14 15 NextLast modified: November 3, 2007
