Abstract : A previous experiment revealed that subjects perceive variation in three different properties of flight simulator visual scenes during low-altitude, high-speed flight. When field of view was reduced, however, the same scene elements were no longer perceived as being uniquely different from one another but combined to mediate a single factor related to scene complexity. The present experiment sought to determine whether this difference could be attributed to lack of optic flow structure off-axis from the heading direction. The same stimuli were shown on a single display window that was oriented to the side of the aircraft rather than in the direction of heading. Results were more similar to those obtained with a full three-window display configuration, thus suggesting that important information for distinguishing among various scene elements is obtained exclusively off-axis from the heading direction.
