It is reported that the efficiency of a teleoperation in stereoscopic images of the working site is lower than that in the direct viewing of the site. It is assumed that one of the causes of lower efficiency of the teleoperation in the stereoscopic images is the difficulty in the fusion of images, which is caused by the imperfect overlapping of images on each eye. In most teleoperations, the convergence of the stereoscopic cameras is fixed at a certain point, usually in the middle of the working area. When the plane of the operator's eye-fixation-point is apart from the plane of the convergence point of the stereoscopic cameras, the two images do not perfectly overlap. It requires a great deal of effort for the images to be fused when the difference in the depth of the two planes is over a certain value. We hypothesized that imperfect overlapping of the images on the left and right eyes would cause a decrease in efficiency for a teleoperation. The results of the experiment led to the conclusion that in order to achieve a good performance in a teleoperation, the convergence point of the cameras should follow the target object on which subjects fixate both of their eyes.
