Researchers at Tokyo University have come up with a technology that is a first and significant step away from the mouse and keyboard – touchable holograms.

[Hiroyuki Shinoda, Professor, Tokyo University]:
"Up until now, holography has been for the eyes only, and if you'd try to touch it, your hand would go right through. But now we have a technology that also adds the sensation of touch to holograms."

The technology consists of software that uses ultrasonic waves to create pressure on the hand of a user “touching” the projected hologram.

Researchers are using two Wiimotes from Nintendo’s Wii gaming system to track a user’s hand.
