Hyperstereopsis associated with helmet-mounted sighting and display systems for helicopter pilots.

摘要

Modern tactical helicopter operations are increasingly being conducted in extreme conditions, often associated with various environmental challenges (such as poor visual cues) and human factors issues (such as fatigue, loss of situational awareness, task saturation, and spatial disori-entation). With ever-growing mission demands, there has been recognition of the need for helicopter aircrew to have all essential mission and flight data available at all times, especially during demanding "head-up, eyes-out" situations. This has led to the development of various forms of helmet-mounted equipment such as night vision goggles (NVG) and helmet-mounted sighting and display systems. The benefits of these devices are that the aircrew can now spend more of their time confidently head-out of the cockpit, actively flying and conducting the mission, with the added benefit of still having ready access to all essential flight and mission data.
