Abstract: A head mounted display assembly including a frame comprising a base (5) adapted to rest on a top portion of a head of a user, a front frame portion (4) adapted to rest against a front portion of the head of the user, and a rear frame portion (6) adapted to rest against a back portion of the head of the user. The assembly also includes an optical display housing (2). Additionally, the assembly includes an adjustment mechanism configured to adjust a distance between the front frame portion (4) and the rear frame portion (6) while maintaining the optical display housing (2) at a constant angle relative to the base (5). The instant abstract is neither intended to define the invention disclosed in the specification nor intended to limit the scope of the invention in any way.

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.
