Dynamic Foveal Vision Display

Conventional head mounted displays (HMD) have several limitations including limited field of view (FOV) and spatial resolution, as well as impeded see-through vision and large size and weight. This limits their ability to provide information to the warfighter and reduces the warfighter"s situation awareness. Trex Enterprises has developed a novel Dynamic Foveal Vision Display (DFVD) technology which provides high resolution (20/20 vision) over a 10 degrees parafoveal view and reduced resolution over a peripheral FOV (50 degrees ) while maintaining low bandwidth requirements. The DFVD is based on retinal scanning display (RSD) technology. The parafoveal high-resolution zone is generated in the user"s gaze direction, where he/she is currently looking, which is monitored by an unconventional, robust, lightweight eye tracker. The eye tracker leverages the RSD hardware. The RSD technology in conjunction with a polycarbonate primary mirror reduces the size, weight and power requirements. The polycarbonate primary mirror with Rugate coatings provides maximum impact resistance and minimal reduction of the see-through FOV. It is ergonomic, compact, and lightweight. In the Phase II program, we will design, fabricate, and demonstrate key critical components of the Trex DFVD, as well as design and build a DFVD prototype and perform a man-worn demonstration using a backpack computer.
