A Study on Tactile Illusions of Temperature and Touch Through Virtual Hand Illusion

Recently, a wide variety of VR content has been provided, and the development of devices that approach the sense of touch is attracting attention. We investigated the sensory experience of "temperature," "smoothness," and "hardness" in virtual space. Unlike previous studies that perform haptic feedback using a glove-type device, we conducted a tactile experiment without using a device by inducing a tactile illusion from visual information using a virtual hand illusion. The results suggests that visual information can evoke a tactile illusion of "temperature" and "smoothness."
