Abstract

A helmet-mounted display (HMD) with a partial binocular overlap field-of-view (FOV) is slated for use with the Army's new RAH-66 Comanche helicopter in order to increase the available size of the FOV. The current investigation examined how FOV configurations affect visual performance in a target acquisition task under demanding viewing conditions. Performance was measured by response time and error rate in the full overlap FOV, the convergent partial overlap FOV, and the divergent partial overlap FOV. Fifteen aviators were required to visually scan for and identify the position of a visually degraded random target from a three by three array of similar distractors in a randomly cluttered FOV as quickly as possible while minimizing errors. The results found a tradeoff in enlarging the FOV by the partial overlap method. Performance was best in the full overlap FOV, where response times were fastest, and worst in the divergent partial overlap FOV, where response times were slowest. The performance decrements for partial overlap were confirmed by the accuracy data, where the partial overlap configurations with the slower response times also had a higher number of misses and a lower percentage of first scores (no-miss target acquisitions). These three performance decrements are most pronounced for lateral targets in the monocular regions of the partial overlap FOVs.
