An Examination of Motion Analysis During Weight Illusion by Impression Change of the Own Body

Abstract

The development of virtual reality technology has made it possible to easily change the appearance of a person, and it has been suggested that the impression change of the appearance using virtual reality avatars affects not only self-perception but also weight perception. We have studied the physical effects of the impression change of the own body during the weight illusion based on electromyogram. As a result, a significant correlation was obtained between the electromyogram and the degree of the weight illusion among the subjects, although the correlation was not significant for each subject. In this study, to investigate the change in motion during the weight illusion, we analyze the motion under the impression change of the own body through a comparison experiment of dumbbells’ weights. The results showed that subjects who obtained a correlation between the degree of impression of the strength of the avatar and the degree of weight illusion had a positive correlation between the degree of impression of the strength of the avatar and the velocity of their motion. The results suggest that the velocity of motion, the degree of impression of the strength of the avatar, and the degree of the weight illusion are related with each other.
