Abstract:

The efficacy of stereopsis cueing in pictorial displays was assessed in a real-time piloted simulation of a rotorcraft precision hover-in- turbulence task. Seven pilots endeavored to maintain a hover by visually aligning a set of inner and outer wickets major elements of a real-world pictorial display to attain the desired hover position. A full factorial experimental design was used. The display conditions examined included the presence or absence of a velocity display element a velocity head-up display as well as the stereopsis cueing conditions, which included nonstereo binoptic or monoscopic, i.e., no depth cues other than those provided by a perspective, real-world display, three-dimensional stereo, and hyperstereo telestereopsis. Subjective and objective results indicate that the depth cues provided by the stereo displays enhanced the situational awareness of the pilot and enabled improved hover performance being achieved with the combined use of stereo and the velocity display element. Pilot control input data revealed that less control action was required to attain the improved hover performance with the stereo displays.
