| Abstract: |
Aperture stops are positioned in the optical train of a partially overlapped binocular display in a such a manner that overlapping portions the binocular boundaries of the left and right fields of view are substantially out of focus, and therefore do not appear as well defined, distracting contours in the visual field. The present invention is particularly well suited for use in virtual reality systems employing head mounted displays.

First Claim:
Show all 28 claims |
What is claimed is:
1. A virtual reality system having a partially overlapped binocular display for displaying simulated three dimensional images to an observer, the partially overlapped binocular display comprising,
- a generator of a first image having a first boundary;
- a generator of a second image having a second boundary; wherein:
- the first and second images are generated such that a predetermined portion of the first image overlaps a predetermined portion of the second image thereby forming a first nasal portion of the first boundary which overlaps the second image and a second nasal portion of the second boundary which overlaps the first image, the system further comprising:
- an aperture step positioned in front of the first and second images, and closer to an eye of the observer than the focal renee or said eye, so as to substantially block the observer's view of the left nasal boundary and the right nasal boundary, the aperture stop being substantially out of focus to the observer.
