Abstract: Different viewing mechanisms are used for left and right eyes. One of the eyes is presented with an image from a single image source that occupies the entire field of view of the eye. The view presented by this first image source is a wide field of view with a relatively low resolution. A second image source presents a second view to the other eye of the user. The second view is a narrower-field-of-view, higher resolution depiction of the same view or scene as presented by the first image source. Additionally, the second image source includes a direct see-through path so that the user can view the real outside surroundings. The combination of low resolution, wide field of view in one eye combined with a high resolution, narrow field of view with see-through in the other eye allows the user to be presented with a computer-generated simulation view having both wide field of view with specific, high resolution at the viewer's visual center of interest.

Abstract: A head-mounted display includes an aperture mask between the eye and a viewfinder to mask the line artifacts resulting from visible edges of mechanisms, such as imagers, within the display. The aperture has a translucent area that matches the geometry of the edge desired to be masked. In an application where a high-resolution image is presented to one eye, centered within a lower-resolution image presented to the other eye, the aperture is positioned to mask the edges of the high-resolution image source. In an application where see-through is desired, the opaque area is sacrificed in favor of a partially transparent mask. The translucent area can be graduated so that a smooth transition area between the edges of the high-resolution display and the lower-resolution display is achieved.
