This report presents the findings of a review of the literature on night vision goggles NVGs, head-up displays HUDs, and helmet-mounted displays HMDs. The review was conducted to identify factors affecting the performance of pilots using the NVG-HMD system that superimposes symbology on the NVG image. The perceptual and attentional problems associated with using NVGs, HUDs, and HMDs are well documented in the literature but are not well understood. The literature suggests that use of the NVG-HMD system is likely to result in several perceptual and attentional problems, most notably errors in distance estimation, inappropriate division of attention, and spatial disorientation. A coordinated program of research on the NVG-HMD system should be undertaken using laboratory simulation devices, flight simulators, and operational aircraft. Priority should be given to investigating the effects of variables that are identified as important in the literature review, and of practical significance to the Army and that have not been determined by design decisions.
