This looks AWSOME !
A new USB device, called The Leap, creates an 8-cubic-feet bubble of "interaction space," which detects your hand gestures down to an accuracy of 0.01 millimeters - about 200 times more accurate than "existing touch-free products and technologies," such as your smartphone's touchscreen. or Microsoft Kinect.
The Leap is available to pre-order now for $70, and is expected to ship early next year. For now, Leap Motion is actually giving away free units and an SDK to developers here
Come on, let's make sure that DJ Sures gets hold of 'the leap'. I am sure he would love to get his hands on one. I also think $70 is a great price, for what you get.
Although I can see this soon becoming installed in Mobile phones and keyboards, I can see a few other uses for it too. Like location mapping for robots in 3D, with 0.01mm depth accuracy ! It seems quite small too (the size of a small candy bar), so ideal to mount on bots.
If you were also clever, you could mount one of these onto a HMD display, like the Vuzix VR Glasses, pointing down at your hands/arms. You can then wave you hands and arms about or point fingers and control your robot. You could even render your own virtual hands/arms in your HMD at the same time....and perhaps use the leap 3D tracker to make your own version of TrackIR on the HMD.
The draw back is that there does not yet seem to be any evidence that this is camera based, so no video/photo captures etc. But who cares, because we all have a camera when we buy the EZ-Robot kit !
