Abstract: A method and apparatus for representing a group of graphic objects so as to maximize usage of a display area on a computer controlled graphics display system. The present invention provides a means for "collapsing" a group of graphic objects so that the group is represented by a container icon. The container icon occupies a smaller amount of display area than the group of objects. The group is recallable (i.e. expanded) by "tapping" on the container icon. Alternatively, the group may be located on a separate accessible area of the display space. The container icon is itself a graphical object and can be moved, copied or deleted. Any change of attributes, e.g. color, of the graphical object causes a corresponding change to the group of graphic objects.

Abstract: A system for the capture and playback of temporal data representing a collaborative activity such as a meeting. Such temporal data is captured by one or more capture devices (e.g. audio recordings or an electronic whiteboard). Temporal data is comprised of timestreams and events. Timestreams are sets of timestamped data which represent some recordable aspect of the meeting. Events are contained within a timestream that represent natural activities that occurred during the course of the session. Events are used to create indices which provide direct access to a point or span in time during the collaborative activity. Playback of a session is performed under the control of a session access device. Coupled to the session access device are a plurality of players for playing back timestreams. The session access device utilizes event information to create a user interface for controlling session replay. The user interface is comprised of a plurality of windows.
