|  This is an interactive stereoscopic display 
                        configuration that provides binocular parallax, motion 
                        parallax, and motion perspective depth cues by determining 
                        the viewer's head position with a magnetic tracker. The 
                        correct viewpoint for the current head position is selected 
                        and displayed in realtime from an optical videodisc holding 
                        over 5000 different viewpoints of a scene.  |
