The effect of thermal stimulation to sole on position

Abstract

We have discovered that vertical force or tactile sensation occurred when temperature of participant's skin changes rapidly. In this illusion, upward motion, pressure or force sensation is elicited when stimulus temperature rises rapidly whereas in the opposite case, downward motion or pulling sensation is elicit-ed. In this paper, we propose to apply this phenomenon to sole to present ground slope. We measured result of correlation between stimulation temperature and front-back direction position of center of gravity.
