New Touchable Holography Uses Wiimotes for 3d Reality

Touchable Holography presented by SIGGRAPH2009

Part 1:
A holographic image floating in mid-air is no longer a mere dream. Provision Holo provides floating images by utilizing a concave mirror. Although you can see the images, you cannot feel any reacting sensation. We use the wiimotes for a simple tracking system.

Part 2:
We use the “Airborne Ultrasound Tactile Display” developed in our lab. Ultrasound pushes objects in the direction of its propagation. Force is generated at the focal point of the ultrasound. The focal point can be moved by controlling the phase delays.

Part 3:
The tactile display attached on the roof gives contact force. You can feel rain drops falling on your hand, or a small creature.
