There is a critical need across the Services to improve the effectiveness of aircrew within the crewstation by capitalizing on the natural psycho-motor skills of the pilot through the use of a variety of helmet-mounted visual display and control techniques. This has resulted in considerable interest and significant ongoing research and development efforts on the part of the Navy, as well as the Army and the Air Force, in the technology building blocks associated with this area, such as advanced head position sensing or head tracking technologies, helmet- mounted display optics and electronics, and advanced night vision or image intensification technologies.
