This paper describes a new stereoscopic display system with extended observable space employing an eye-position tracking technique. In this display system, as a video projector is mechanically driven according to the viewer's eye position, the left- and right-eye images continuously enter the viewer's eye. Thus the viewer can move and continue to observe the stereoscopic image, and it is possible to extend the stereoscopic area widely. Experimental equipment consists of an LCD video projector, a lenticular screen, a motor-driver for the projector, a video signal multiplexer and an eye-position tracker. Experimental results show that the stereoscopic area moved according to the movement of the projector.
