Body cyberization by spatial augmented reality for reaching unreachable world

This paper presents a novel body cyberization technique, in which we visually extend the length of a user's arm by projected imagery to allow the user to reach unreachable objects. We thoroughly design the body cyberization model such as graphical representations, action components, and interaction techniques. Through a psychophysical experiment, we investigate if a user can feel a sense of ownership for a projected hand. We also conduct a user study to make it clear that projection-based visualization of extended arm provides users with better usability. We build various application systems and demonstrate the feasibility and effectiveness of the proposal.
