KUSUGURI: Visual Tactile Integration for Tickling

It is widely known that a tickling sensation can be felt when simply watching a tickling gesture adjacent to our body regardless of whether there is physical contact. We focus on a palm suitable for physical contact, and propose the method including a visual tactile display which appears as a part of the palm. Users can observe a moving fingertip which looks as if someone is tickling the palm with his/her fingertip, and users feel a simple and slight vibration provided from the device during being tickled. As a result, users perceive tickling sensations due to sensory integration between the visual cues (the movement of fingertips) and tactile cues as (simple vibration). Furthermore, our proposed method also enables bidirectional tickling using the same devices, and can be applied to other parts of body, or wherever the device can be placed.
