We present buttock skin stretch device to induce force perception. First of all, we investigated whether shear force can be presented by skin displacement of the buttocks. As a result, it was confirmed that the magnitude of the perceived force transitions according to the deformation amount in a substantially linear relationship. In addition to visual stimuli inducing visual induced self-motion perception, we investigated whether acceleration self-motion perception can be modulated by skin deformation of buttocks. As a result, there was a significant difference in the sense of acceleration of self motion among some skin deformation amount conditions, and the sensation of acceleration of self motion was caused by the force perceived at the buttocks.
