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.

Claims

1. A displayer comprising:

a display mechanism for displaying a plurality of images to one or more viewers wherein the display mechanism interleaves at least a portion of the plurality of images and wherein the interleaving varies at least in part as a function of where one or more of the viewers are in space.

2. The displayer of claim 1 wherein one or more of the plurality of images vary at least in part as a function of where one or more of the viewers are in space.

3. The displayer of claim 1 wherein a stripe pattern is used to interleave at least a portion of the plurality of images.

4. The displayer of claim 1 wherein the interleaving is time multiplexed.

5. The displayer of claim 1 wherein the interleaving is space multiplexed.

6. The displayer of claim 4 wherein the interleaving is space multiplexed.

7. The displayer of claim 3 wherein a plurality of stripe patterns are used to interleave at least a portion of the plurality of images.

8. The displayer of claim 3 wherein the width of the stripe pattern varies at least in part as a function of where at least one of the plurality of viewers are in space.

9. The displayer of claim 8 wherein the width of the stripe pattern varies dynamically in relation to where at least one of the plurality of viewers are in space.

10. The displayer of claim 3 wherein the location of the stripe pattern varies at least in part as a function of where at least one of the plurality of viewers are in space.

11. The displayer of claim 8 wherein the location of the stripe pattern varies dynamically in relation to where at least one of the plurality of viewers are in space.

12. A displayer comprising:

a display mechanism for displaying a plurality of images to one or more viewers wherein the display mechanism interleaves at least a portion of the plurality of images and wherein the interleaving varies at least in part as a function of at least one of the rotation or the tilt of one or more of the viewers'"'"' heads.

13. The displayer of claim 12 wherein the interleaving is time multiplexed.

14. The displayer of claim 12 wherein the interleaving is space multiplexed.

15. The displayer of claim 13 wherein the interleaving is space multiplexed.

16. The displayer of claim 12 wherein a stripe pattern is used to interleave at least a portion of the plurality of images.

17. The displayer of claim 12 wherein a plurality of stripe patterns are used to interleave at least a portion of the plurality of images.

18. The displayer of claim 16 wherein the width of the stripe pattern varies at least in part as a function of where at least one of the plurality of viewers are in space.

19. The displayer of claim 16 wherein the width of the stripe pattern varies dynamically in relation to where at least one of the plurality of viewers are in space.
