Stress Estimation in Unconscious Rhythm Induction by Auditory Stimuli

Abstract

Stress caused by the misalignment of movements in cooperative work with robots has become a problem. In this study, we used the synchronization phenomenon to induce the human work rhythm by sound, and estimated and evaluated stress based on heart rate variability when a change in sound is perceived. Subjects performed a tapping task as a periodic task in a cooperative work environment. Heart rate was measured during the experiment, and the stress state was estimated from the heart rate variability. Results: It is not clear whether it is possible to induce stress while suppressing its increase under the conditions of the present study. However, it was suggested that it is possible to induce the subjects’ work rhythm under certain conditions.
