A Comparison of Soldier Performance Using Current Land Navigation Equipment with Information Integrated on a Helmet-Mounted Display.

Abstract : The report describes a field study designed to measure soldier performance of land navigation and other mission tasks using current navigational equipment and to compare these data with performance using navigational information integrated on a helmet-mounted display (HMD). Measures of stress, cognitive performance, and workload were also obtained. The results indicated that the soldiers traveled less distance between waypoints and experienced lower levels of mental workload using information presented on the HMD than they did using current navigational equipment. As might be expected, differences in time between manual and automatic map updates were significant, but no differences were found between current equipment and the HMD condition in object detection, determination of magnetic azimuth, or call for fire tasks. Differences between conditions in levels of stress and cognitive performance were not significant.
