Japanese Scientists Create Touchable Holograms

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.

The technology was introduced at SIGGRAPH, an annual computer graphics conference, and has so far only been tested with relatively simple objects.

But its inventors have big plans for touchable holograms in the future.
