Using ultrasound technology, researchers at the University of Tokyo have developed a holographic projector that displays three-dimensional virtual objects you can feel with your bare hands.   The system is currently on display at SIGGRAPH 2009 in New Orleans.

The system consists of a Holo display (developed by Provision Interactive Technologies), a pair of Wii Remotes that track the position of the user’s hand in front of the screen, and an “Airborne Ultrasound Tactile Display” unit that shoots focused ultrasonic waves at the hand to create the sensation of pressure on the skin.

By controlling the movement of these focused ultrasonic waves — which can produce up to 1.6 grams-force of pressure within a 20-millimeter-wide focal point — the projector can recreate virtual objects that seem to have physical mass. In the video above, the projector displays a tangible virtual bouncing ball, raindrops, and a small creature that runs around on the user’s hand.

  • Dear friends would appreciate information on virtual holographic projectors. Close to shoot me in the execution of a magical effect on stage, projecting on stage virtually empty space (Just like the trophies presented fotebool) and then crumble with my real appearance. This is a routine for a magic contest Magico. Thanks

  • This one looks very interesting. Apart from conventional projectors this one will be used in theaters for magic shows to create 3-D effects. I am very much interested to know the price of it. I think it will be much expensive. What do you think..??
