Teleoperation is a very useful technique in the case of carrying out tasks in hazardous and/or remote sites. In order to carry out the tasks in high operational efficiency, a video system to display the workspace for an operator is important. In this study, we developed a spatial multi-resolution stereoscopic video system which has variable convergence point, and confirmed the effect of keeping an overlapped area large at the working point by varying the convergence point continuously with the spatial multi-resolution stereoscopic video system.As the results of this experiment, it was clarified that the operational efficiency with teleoperation through the spatial multiresolution stereoscopic video system was improved by keeping an overlapped area large, which resulted from varying the convergence point. That is, in order to carry out tasks with teleoperation in high operational efficiency, the system is required to vary its convergence point to keep an overlapped area large.
