Abstract:
The response times to and correct identification of target stimuli superimposed on panoramic scenes were measured under conditions of restriction and nonrestriction of peripheral vision. Twenty-five male subjects were assigned randomly to experimental conditions and required to search for target stimuli under simulated visual flight conditions of varying color and terrain features. A simulated helmet-mounted device was used to restrict peripheral vision. The data are viewed as supporting the position that the intrusion of a helmet-mounted device into a pilots field of view can result in a significant decrement to his target vigilance performance. Possible implications in human engineering design and subsequent research efforts are discussed. Modified author abstract
