Stereoscopic display
First Claim
1. A display system, comprising:
- first image generating means adapted to provide a desired image;
second image generating means adapted to provide a desired image;
means for projecting the images generated by said first and said second image generating means along at least one predetermined path toward an observer;
control means in said at least one path for adjusting the images projected along said path depending upon the position of said observer;
means for monitoring the position of said observer and for generating an electrical signal in response to said position; and
means for adjusting said control means in said at least one path based on said electrical signal, said last mentioned means being operatively connected to said position maintaining means.

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.

10. A display system, comprising:
-
first image generating means for providing a first desired image; second image generating means for providing a second desired image; means for projecting the first and second images generated by said first and said second image generating means along at least one predetermined optical path toward an observer; control means in said at least one path for adjusting the images projected along said path based upon the position of said observer; means for monitoring the position of said observer and for developing an electrical signal in response to said position; and means for operating said control means in said at least one optical path based upon said electrical signal, said last mentioned means being operatively connected to said position maintaining means. - View Dependent Claims (11, 12, 13, 14, 15, 16, 17, 18, 19, 20, 21, 22)

23. A method of providing a three dimensional view to an observer comprising the steps of:
-
generating a first image for projection toward a first eye of the observer; generating a second image for projection toward a second eye of an observer; monitoring the position of the observer; and changing the projected image perspective as a function of observer position.
