Psychophysiological Effects by Interaction with Mental Commit Robot

Abstract

We have been working on research and development of mental commit robot which aims to provide humans mental effects such as enjoyment and relaxation. In the previous research, we have performed subjective evaluation of mental commit robot by some interview forms. The results showed physical interaction improved subjective evaluations. Moreover, a priori knowledge of a subject had influence into subjective interpretation and valuation. In this paper, we applied physiological measurements to investigate influence to human by physical interaction with mental commit robot. As physiological measurements, we applied the electrocardiogram (EGG), respiration rate and the electrodermal response (EDR). And we measured mood state and liking for the object by using the profile of mood states (POMS) and SD method. The finding of experiments suggested changes of autonomic response and mood state caused by physical interaction with mental coconut robot. Moreover, it was suggested that there were some differences in autonomic response by subjectivity.
