Visual Simulation Requirements for Aircraft Aspect Recognition at Real World Distances
Abstract
A research program is underway whose goal is to provide engineering guidelines on target image sufficiency for training tactics and maneuvering skills in ground-based flight simulators. The experiment examined aspect recognition sensitivity, i.e., the distance at which subjects could determine the orientation of another aircraft. The aspect recognition task was simplified in the following ways: a) only 16 stationary targets orientations of a TA4J aircraft were presented; b) targets had essentially the same length/width ratio; c) subjects made binary up/down judgements; and d) a staircase method provided percent detection thresholds for aspect recognition range. In Phase I, four different target luminances and three background luminances were combined with four different levels of projector resolution in a partial parametric study to access the relative effects of contrast, resolution, and brightness on aspect recognition. In Phase II, motion and direction of view were varied. Phase III replicated Phase I to determine whether sequence effects occurred in this repeated measures study. Through a series of ministudies, Phase IV examined subsidiary effects (viz., different aircraft, different perceptual judgements, difficulty level of the silhouette stimuli, and poorer resolution). Keywords include: Visual displays, Training equipment, Flight simulator specifications, Individual differences, Design criteria, Aspect recognition, Air combat maneuvering, Pilot training.
