Effects of Information Load, Location, and Mode of Observation on Detecting and Identifying Brief Targets

Abstract

PARAMETERS, TASK VARIABLES, AND OPERATOR PERCEPTUAL LIMITATIONS ON ABILITY OF Night Vision Device operators to process visual information quickly and accurately. For untrained observers, target brightness requirements were higher for identification than for detection, but were about equal for both responses with target exposure times greater than a critical time of 0.10 to 0. 17 second. With shorter exposure times, the target brightness needed for detection or identification increased as exposure time decreased. Increasing information load and randomizing target location raised brightness requirements for identification. The results suggest that operator performance might be improved significantly by special training to increase the observer's area of attention and his capacity to process visual information.
