Abstract
An improved three dimensional display device, for a single viewer. To the apparatus of U.S. Pat. No. 5,132,839 is added a mechanism for tracking the eye motion of the viewer. Because the control system "knows" the angles at which the device must project the frame images, only two (stereoscopic) frame images need to be projected in each frame, and a more complete illusion of three dimensionality, with respect to both lateral and vertical movement of the viewer, is provided.
