Touchable 3D Character Projected Into a Real Environment

RePro3D, developed by a research group at Keio University, is a multi-perspective, naked eye 3D display in which viewers can touch a 3D character floating in midair. The touchable 3D display is a combination of three elements. A mechanically-controlled model environment, a tactile interface and a glasses-free 3D integral imaging display.

The input interface uses an infrared camera to recognize the movements of the user's hand, and the character on screen reacts to the movements instantly. They are currently developing a system which can replicate the sensation of directly touching the image by having the user wear a tactile feedback device on their finger.
