Autostereoscopic display
First Claim
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.

Abstract
An apparatus for displaying an image to an observer. The apparatus comprises a display screen upon which stripes of the image appear in at least three distinct phases. The apparatus comprises 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. The apparatus comprises 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, 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. The apparatus comprises an eye tracker for identifying the locations of the observers'"'"' eyes and providing the location to the computer. A method for displaying an image to an observer.

7. A method for displaying an image to an observer comprising the steps of:
-
identifying locations of the observer'"'"'s eyes with an eye tracker; sending the locations to a computer with the eye tracker; rendering two 3D scenes, one for each eye for arbitrary observer position and orientation and for each of the three phases, a proper left/right alteration pattern which are interleaved into three successive time phases as red, green and blue, respectively; displaying on a display screen stripes of the image in at least three distinct phases; and forming a stripe pattern which lets through only ⅓
of each stripe of the image that continually changes the width and positions of the stripes as the observer moves on the display screen during each of the at least three distinct phases with a light blocking shutter disposed in front of the screen. - View Dependent Claims (8, 9, 10, 11)

12. A displayer comprising:
-
a sensor mechanism for identifying at least one of tilt and rotation of at least one viewer'"'"'s head; and a mechanism for displaying a plurality of images to one or more viewers wherein at least a portion of the images are a function of at least one of tilt and rotation of at least one viewer'"'"'s head, said displaying mechanism in communication with the sensor mechanism, the displaying mechanism includes a computer which receives information from the sensor mechanism identifying at least one of tilt and rotation of at least one viewer'"'"'s head and produces said images, the computer causes the images to be displayed. - View Dependent Claims (13, 14, 15, 16, 17, 18, 19, 20)

21. A displayer comprising:
-
a sensor mechanism for identifying where V viewers are in space, where V is greater than or equal to 1 and is an integer; and a displaying mechanism for displaying U different images to V different viewers where each image is a function of where each viewer is in space to which the respective image is associated, where U is greater than or equal to 1 and is an integer, said dis playing mechanism remote and apart from and out of contact with the V viewers, said displaying mechanism in communication with the sensor mechanism, the displaying mechanism includes a computer which receives information from the sensor mechanism identifying where each viewer is in space and produces said images, the computer causes a first image of the U images and a second image of the U images associated with a first viewer of the V viewers to be shown interleaved on the first screen wherein spacing between the interleaved first image and second image varies as a function of where each viewer is in space to which the respective image is associated.
