This paper proposes a new shadow interface system that provides tactile feedback from a user's shadow to physical body. When users obstruct the projected image by their bodies, wearable photoreactive tactile displays receive the light information; they decode it and transmit tactile sensation. The proposed system does not require complex sens- ing, complicated settings and communication systems; it can perform high speed tactile feedback with the information di- rectly received from the projected light. Perspective projection of the projected image and occluding objects that gen- erate shadows is preserved in principle; all the users have to do is obstructing the projected light. In this paper, we present the concept, the first prototype of the system, and basic evaluations. The system can easily serve as a human interaction system with touch sensitive shadow, and it has potential applications in the areas of interactive entertainment and user interfaces.
