‘Virtual’ palm sized keyboard that can do more than normal ones!

Published On: Fri, Dec 2nd, 2011 | Computer Science | By BioNews

A full-size, laser-projected keyboard has been developed by a Korean company, which could fit in the palm of the hand.

Korean company Celluon has been developing virtual keyboards for several years and their latest product is the Magic Cube, a small box that fits in your hand yet provides a full-size keyboard when needed.

Switch it on, sit it on a desk and it projects an image of a keyboard on to the surface in front of it.

Tap the virtual keys and the corresponding characters are communicated wirelessly to any compatible device, from a laptop to a smartphone.

The principles involved are very simple, as the projection of the keyboard is just made by a tiny projector at the top of the box.

At the bottom of the box beams of infrared light are emitted just above the surface of the desk.

As your fingers tap the surface they cut through these beams, which are reflected up to a camera in the middle of the box.

The camera sees the reflection and works out from its position which key you have “pressed”, the Sydney Morning Herald reported.

Though the Magic Cube is clever it is essentially just a very portable replacement for a real keyboard.
