Abstract
Techniques for enabling video conferencing with interactive sharing of drawings and/or other information. In one set of embodiments, a system is provided that includes a drawing surface, a video camera embedded or integrated into the drawing surface, and a front projector. The drawing surface can capture drawings made on the surface by a user, and the video camera can capture a video stream of the user. The system can send digital information representing the captured drawings and the video stream to a remote system. The system can also receive digital information representing drawings made by a remote user and a video stream of the remote user from the remote system. The front projector can project a video signal onto the drawing surface that incorporates the captured drawings, the drawings made by the remote user, and the video stream of the remote user.
