This experiment compared accuracy and response time of subjects on a conventional tactical display with their accuracy and response time on a perspective tactical display. The distinguishing feature of the perspective display is its representation of vertical, as well as horizontal information in perspective. Altitude information is symboically presented on the display. In contrast, current tactical display systems provide only two-dimensinal views requiring numerical representation for altitude informtion. The subjects were volunteers from surrounding Naval facilities. The subjects were required to perform two tasks: (1) detect threats, and (2) select the closest interceptor for each detected threat. Errors and response time were recorded for each subject by a computer program. The experiment revealed a significant reduction in errors of detection and interception with the use of a perspective display. Response time for selecting interceptors was greatly reduced.
