Abstract

We did a tracking experiment in the virtual space to investigate the effect of an overlap rate between fight and left images of a stereoscopic image pair on work performance. Twelve subjects tried to track a target moving around in a three- dimensional virtual space by the cursor that they controlled with a 3-D mouse. The high overlap rate condition was 100% overlapped and the low overlap rate condition was 50% overlapped. The convergence point of the virtual video cameras was fixed during the experiment. We measured the difference of the position between the target and the cursor in horizontal, vertical, and depth axes. The results showed: (1) the difference between the target and the cursor in the low overlap rate condition was larger than that in the high overlap rate condition; (2) the difference in depth was larger than these in horizontal and vertical axes; (3) the difference in depth occurred when the target moved far away from the subjects.
