Abstract
Future integrated helmet systems are being conceived and developed with a single helmet-mounted display (HMD) device to display a wide range of visual information to the soldier. Since many future helmet system designs are looking to integrate many different visual information functions into a single display and disconnect and remove the image sensor device to another location on the helmet, this study investigated the effect of different image sensor positions on soldier performance. A three-day field trial was undertaken at the McKenna MOUT site in Fort Benning, Georgia with sixteen regular force infantry soldiers. Participants were required to perform tasks requiring visual psychomotor coordination while observing the visual field through a day video camera mounted in four different positions on the helmet. Testing included bench-top dexterity/manipulation tests (i.e. close-in tasks), terrain traverse and room clearing through urban buildings (i.e. close quarter), and target detection and engagement tasks at larger ranges in the urban village (i.e. near engagement range). The use of a video system (disconnected image sensor and head mounted display) generally resulted in a significant reductions in soldier task performance times and accuracy for all offset video positions, as compared to the normal vision (without a visual display system). Comparing the four offset positions, objective performance measures indicated that the central and horizontally offset positions were g
