Patent Images

1. An apparatus for displaying an image to an observer comprising:

  • a display screen upon which stripes of the image appear in at least three distinct phases;

    a light blocking shutter disposed in front of the display screen forming a stripe pattern which lets through only ⅓

    of each stripe of the image on the display screen during each of the at least three distinct phases;

    a computer connected to the display screen and the light blocking shutter which changes the phases so in each phase the stripe pattern is shifted laterally, which renders 2 3D scenes corresponding to the eyes of the observer for arbitrary observer position and orientation, which produces a proper left/right orientation pattern for each of the three phases and which interleaves the left/right orientations into three successive time phases as red, green and blue, respectively, and that continually changes the width and positions of the stripes as the observer moves; and

    an eye tracker for identifying the locations of the observers'"'"' eyes and providing the location to the computer.
