Abstract
A system for controlling the playback of a recorded session utilizing a window acting as a player for playing back a timestream for a shared representation media, such as an electronic whiteboard. Timestream and event information for the session is captured by one or more recording devices. Playback of a session is performed under the control of a session access device which utilizes event information to create a user interface for controlling session replay. The user interface includes the window for playing back the timestream of a shared representation media. Each graphical object in the window is associated with one or more events (e.g. a creation event, an editing event, a move event or a deletion event). Selection of a graphical object enables playback time to be moved to the time for one of the associated events. Selection may also be made on an area of the window. This will enable the user to view all events related to graphical objects in the selected area (as some graphical objects may be erased or moved).
