From: Ron <FISCHER@RUTGERS.ARPA> This could be done in a rather straightforward manner, place a slightly convex mirror on your forehead and an infrared projector on the terminal that shines a wide beam in the shape of an "L". Place IR detectors along the top and right sides of the display. I have an objection to this technique however. Try moving your head to "aim" at different points on the screen for a few minutes. Imagine doing this all day. Would this characteristic motion persist? Making you look like a pigeon? (ron) -------

From: Mike Peeler <MDP@SU-SCORE.ARPA> Ron, I doubt that users of such a device would develop a tic like that. People with glass eyes are taught to look with their whole head, but they do not look like pigeons. Cheers, Mike -------
