Presenting realistic tactile sensations in a virtual space requires to provide appropriate stimuli to both cutaneous and proprioceptive senses. This study aims to present high-quality softness sensation by presenting repulsive force and spreading cutaneous sensation according to the amount of indentation. Touch X USB was used as a general force feedback device, and electrical stimulation was used as a means of presenting cutaneous sensation. We measured the change in contact area of flexible samples, and applied an electrical stimulus that reproduced the increase in the contact area of the sample simultaneously with the force sensation. This paper investigated the effectiveness of the fusion of cutaneous and force sensation through a psychophysical experiment and showed that the reality of softness sensation was improved using simultaneous presentation.
