Siggraph - Touchable Holography

Presented at the 2009 Siggraph Emerging Technologies conference, this is just the beginning of something pretty revolutionary in the way we understand 3D imaging.

"Researchers at the University of Tokyo are working to create holographic displays that mimic the sensation of interacting with solid objects....researchers place a reflective marker on a person's hand and use Nintendo Wiimotes to track the position of the hand relative to the hologram. As the hand gets near the hologram, the display triggers a feedback mechanism, which feeds acoustic radiation pressure to the hand, creating the sensation that the person is touching an object. At the same time, the hologram reacts to the hand's position, and can be batted, grabbed, or floated based on the hand's position." -from I09
