Effect of Stereoscopic Viewing on Human Tracking Performance in Dynamic Virtual Environments

摘要

In this paper, we present the results of a human factor study aimed at comparing the effect of stereoscopic versus monoscopic viewing on human tracking performance. The experimental paradigm involved tracking and grasping gestures toward a 3D moving object. This experiment was performed using different frame rates (from 28 frames per second (fps) down to 1 fps). Results show that monoscopic viewing allowed stable performance (grasping completion time) down to 14 fps. Stereoscopic viewing extended this stabilty to 9 fps, and decrease task completion time by 50 % for frame rate under 7 fps. We observed that stereoscopic viewing did not much increase performance for high frame rates.
