Researchers at the University of Tokyo have this week demonstrated at SIGGRAPH09 a holographic system capable of both interaction and touch feedback.
The video above shows a system utilizing the Nintendo Wii Remote, an airborne ultrasound display, and holographic unit, to produce Touchable Holography. The demonstration includes a holographic ball which can be moved by pushing it with the hand, or laying your palm flat and it being dropped and bouncing off.
This interaction alone is impressive, but the researchers went one step further and added touch feedback so you can “feel” what is happening too. This is achieved with the airborne ultrasound display matching what is happening with the hologram. The ultrasound waves can apply a force of 1.6 grams and can be directed on to a 20mm area making it quite accurate.
Examples include holographic rain drops falling on an open palm which you can apparently feel. A small animal also runs around your hand with the touch matching the movement.
Check out the impressive video above to see the system in action.
