Some questions come to mind: 1) How bad is the view of a screen for one person when the screen is tracking another person? Is this inherently a solo device? 2) Could the position data also be sent to the computer building the image so both horizontal and vertical motion parallax can be computed? The image could be regenerated for the different eye-positions, giving the illusion of looking at nearby objects through a window as the viewer moves. 3) How intrusive is the target for the tracking device (correct me if my assumption is wrong, but I would guess from your description that the viewer has to wear some sort of optical target which the sensors detect)? -- ------------------------------------------------------------------------ Speaker-to-managers, aka Bruce Cohen, Computer Research Lab email: brucec@rl.labs.tek.com Tektronix Laboratories, Tektronix, Inc. phone: (503)627-5241 M/S 50-662, P.O.
