Proposal of maneuverability index for remote control systems focusing on the “sense of unity” and its verification

Abstract

In this paper, we propose maneuverability index focusing on the “sense of unity” as a new performance evaluation method for remote control systems. We used the Crossmodal Congruency Effect (CCE) for the quantitative evaluation of the “sense of unity”. We verified the validity as a maneuverability index of “sense of unity” evaluated by CCE. We compared the measured CCEs between the systems which are different in terms of operation force of the master device and camera view orientation of the remote environment. As a result, task performance and “sense of unity” results were consistent. It was suggested that “sense of unity” could be used as an appropriate maneuverability index. Finally, we propose a method to compensate for a bias effect of CCE due to the appearance similarity of target objects to human hand.
