HEAD MOUNTED DISPLAY WITH FULL FIELD OF VIEW AND HIGH RESOLUTION
First Claim
1. A head mounted display comprising for each eye of a user of the display:
- a plurality of lenses positioned relative to one another as though each of the lenses is tangent to a surface of a first sphere having a center that is located substantially at a center of rotation of an eye of a user of the head mounted display; and
a plurality of displays positioned relative to one another as though each of the displays is tangent to a surface of a second sphere having a radius larger than the first sphere'"'"'s radius and having a center that is located at the center of rotation of the eye of the user;
wherein each of the displays corresponds to at least one of the lenses, and is imaged by the corresponding lens.

Abstract
A head mounted virtual environment display with high visual resolution and a full field of view is disclosed. The display uses an optical system in which the video displays and corresponding lenses are positioned tangent to hemispheres with centers located at the centers of rotation of a user'"'"'s eyes. Centering the optical system on the center of rotation of the eye allows both a full field of view and high fidelity visual resolution, without compromising visual resolution. A multi-panel video wall design for the video displays allows each lens facet to image a miniature flat panel display at optical infinity. The flat panel displays are centered on the optical axes of the lens facets. A parallel graphics architecture uses data from high resolution and accuracy head trackers and built-in eye trackers to generate high detail 3D models at high frame rates with minimal perceptible lag. Resolution for central vision is optimized with a roaming high level of detail window, and slip artifacts associated with rapid head movements are eliminated using freeze-frame.
