E.S.P.: Extra-Sensory Puck in Air Hockey using the Projection-Based Illusion

E.S.P. (Extra-Sensory Puck) provides a new experience by introducing optical illusions to air hockey. The perception of a solid puck randomly hit by a player is altered to show various physics-defying appearances and motions to the player’s naked eye. Such altered perceptions are based on our high-speed projector-camera system generating stimulation patterns onto the moving puck. This paper presents two demonstrations. The first is the invisible puck, where the hit puck is camouflaged to disappear on the table. The second is the altered motion, where the direction and speed are altered.
