Experimental Design for the Evaluation of a Multimodal Feedback in Multi-Robot Teleoperation

Abstract

In this paper, we propose a multimodal (i.e., visual and force) feedback method to enhance a human operator’s situational awareness in multi-robot teleoperation using only local information of the robots. The proposed method, then, are evaluated via a psychophysical experiment. The visual feedback is developed with local (real) views captured by an on-board camera in each slave robot and a global (fabricated) one regarding the formation of all slave robots as well as directions of the cameras. Position/velocity information of the slave robots is transmitted to the operator as the force feedback. We anticipate to find the benefit of the proposed multimodal feedback in multi-robot teleoperation and to let us design an enhanced multimodal feedback with this finding.
