Talk:Video Chat

The digital whiteboard functionality would be especially useful as a literal chalkboard replacement. If the activity supports a broadcast mode, then a teacher could use her XO as a whiteboard, and all the children could watch on their own screens. This even solves one of the problems of chalkboards: not being able to face your audience and draw at the same time. Additionally, if it is possible to record the drawing over time simultaneously with audio, this would provide an easy way to record a lecture for later playback. Such functionality would also be useful to students, to review the lecture material while doing an assignment. Finally, allowing students to draw on top of the whiteboard without rebroadcasting their modifications would permit a kind of note-taking/personalization of the lecture. Ben 11:46, 18 May 2007 (EDT)
