Abstract : The objective of the effort was to study the effect that certain critical real-time display parameters had on operator target acquisition performance. Detection and recognition performances were investigated as a function of changes in display size, display luminance, target to background contrast, image quality, target type, and number of targets. The results demonstrated that display size and luminance were found to have the largest effect on detection time and probability of detection, whereas target to background contrast had the most important influence on recognition performance. Records of eye movements during the search task were used to investigated scanning patterns. (Author)
