A study on influence of time delay in teleoperation

While a large number of studies have been made on teleoperation, most of these studies are focused on the human interface, the communication, the hardware devices, and stability of systems. Though many studies to overcome time delay in teleoperation have been done, there are few studies about including human factors in teleoperation. We focus on human not having the receptor which perceives time directly, and perform an experiment to find out how the human operator perceives time in teleoperation. In this paper we investigate the quantitative evaluation of operability that depends on the communication time delay in teleoperation and time perceptions of the human operator. In addition, we propose a guideline of human-interface in teleoperation. Selected experimental results are shown with comments
