lUse to Index Videotape
lWhat was the meeting discussion when this class was added?
During the recognition process, events, such as addition, deletion, movement, and text annotation of drawn objects are processed and recorded.

We then associate the timestamps of the events with the video and use them to index the videotape, audio, or screen capture of the design meeting.

This allows us to ask such questions as, what was the meeting discussion when this class was added? The system could then provide us with the appropriate videotape segment.
