Abstract
A display system is provided which gives an illusion of depth to an observer by generating left and right eye image projections for view by the observer. The device includes an observer tracking system which monitors the position of the observer and adjusts the projected scene perspective as a function of observer head position. In the preferred embodiment, the display system is housed in an enclosure adapted for use in arcade video game devices. The tracking device preferably is a plurality of light sensitive photo cells which are monitored to determine observer position in a predetermined field of view. The left and right image scene perspective is adjusted to accommodate observer positions within that field of view as those positions change.
