Illusion of Wet Sensation by Controlling Temperature and Softness of Dry Cloth

In order to create a device that produces the sensation of wet cloth, we have proposed a method to augment the wet sensation of dry cloth. This paper investigated whether controlling the surface temperature and softness of a cloth could reproduce the wet sensation or not. Participants scored their feelings after touching the cloth with different temperatures and softness. Results indicated a tendency to perceive a wet sensation equivalent to actual wet cloth by not only decreasing the temperature but also increasing softness of the cloth.
