Touch Screens and Beyond!

While researching ways to make the iMacs into touch screens I found and updated an old technology that can go much much further than a simple touch.
The Leap motion system can detect hand gestures, positions, fingertips and so on in minute details.
Although discontinued, I was able to take an old version and update it with my own 3D hands.
It successfully detected 2 hands and 10 fingers (or thumbs), and at one point detected Suzie's third hand.

Here is an initial test of the device which incidentally will cost only 3,000 yen per computer!

So instead of touch screens we get this! And exceptionally cheap too.

It is even accurate enough to play a virtual piano!
