Effect of stereoscopic viewing on human tracking performance in dynamic virtual environments

Abstract

In this paper, we present the results of a human factor study aimed at comparing the eect of stereoscopic versus monoscopic viewing on human tracking performance. The experimental paradigm involved tracking and grasping gestures toward a 3D moving object. This exper-iment was performed using dierent frame rates (from 28 frames per second (fps) down to 1 fps). Results show that monoscopic viewing al-lowed 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.
