The M2DART provides a portable simulator system that can be deployed for a variety of training tasks and at numerous locations around the globe. Although its uncollimated, tiled displays allow for a small footprint, the viewing distance is both close (nominally 36") and varies significantly as a user moves their head from tile to tile. This difference between HMD focus and vergence and the varying distance to the simulator screen can cause human factors issues. These issues can manifest themselves as blurry imagery, doubled imagery or more latent effects such as eyestrain which will not be the same as for the real world, since most of a pilot's real world is at or near optical infinity. Our goal under this program is to test different methods of reducing vergence mismatch effects to determine which is the best one to implement in the M2DART and other simulators. Our extensive experience in the design and development of HMDs, coupled with our experience in performing human factors testing will ensure that we provide the Air Force with the right solution.
