Abstract
The purpose of this study was to evaluate the effectiveness of three visual depth cues, and combinations of these cues, in a dynamic air situation display. The study was conducted to help determine how best to display aircraft location to a pilot. Three different depth cues (stereo 3-D, aerial perspective, and familiar object size), were investigated. Additionally, two levels of display density (13 or 25 aircraft) were evaluated. The results of the study indicated that the number of depth cues, which ranged from zero to three, affected the subject's ability to determine aircraft location. Display density also affected performance. However, the particular type of depth cue did not have a differential effect. In other words, it makes a difference if one or two depth cues are displayed, but not the particular cues used.
