Comparison of Four Unattended Ground Sensor Displays
Abstract
The Battlefield Information Systems Technical Area of the Army Research Institute is concerned with human factors problems of surveillance information presentation and interpretation. The research presented here compared the relative effectiveness of four different unattended ground sensor (UGS) displays--an X-T plotter, and three variations of the situation map display--in terms of their effect on monitor performance. Four two-hour UGS scenarios were compiled from previously recorded field tests of military targets. The recordings were played back to activate the displays during experimentation. Sixteen Naval personnel (eight relatively experienced with UGS and eight inexperienced) were given training on the displays. Each subject then monitored each display in turn for two hours, reporting target information as he would operationally. The reports were compared to known ground truth and were scored on total detections, false alarms, detection accuracy, and target direction (i.e., direction of target movement). Operator performance was unaffected by the type of display used. Operators were able to detect a higher percentage of targets during periods of low target activity than during periods of high target activity. However, the accuracy of the detections was higher during the high activity period. Levels of experience did not have a significant effect on performance.
