Effects of Target Size, Target Contrast Viewing Distance, and Scan Line Orientation on Dynamic Televisual Target Detection and Identification
Abstract
The report describes a simulation research study which measured the effects of target size, target-to-background contrast, television raster scan line orientation, and display viewing angle on both target detection and target identification using television. One hundred twenty different simulated air-to- surface target 'attacks' against buildings on a three-dimensional terrain model were video tape-recorded using a 525-line television system. These attacks were then shown to 16 subjects whose tasks were to detect the target from its background and to identify it from a number of alternatives shown on briefing photographs. Performance measures were slant range at correct detection (SRD), slant range at identificatioN (SRI), and probability of correct identification (PCI).
