Re: Precise 3D hand/computer control

'The distance between you and the virtual world is about to get even smaller. David Holz and Michael Buckwald, co-founders of startup Leap Motion, have created a 3-D motion control device that lets users control their computers by gesturing with their hands instead of using a keyboard or mouse.

The technology at work is reminiscent of that in Microsoft's Xbox Kinect device, which allows players to use their bodies as controllers or input devices. With the Leap, your fingers and hands are the controllers. Unlike the Kinect, the Leap uses a different technology that the creators say allows for far greater accuracy and precision within a smaller space.

Holz and Buckwald claim the Leap is accurate to within 1/100 of a millimeter and 200 times more sensitive than existing motion-sensing technologies. In a demo, Holz pointed at a laptop screen and traced the word "hello" in the air with his index finger while keeping his hand still and making only minimal movements with his finger. His gestures were processed and displayed simultaneously on the computer screen.'

I am concerned about the lack of tactile feedback.  It is hard to beat a mouse and the hands feel more comfortable resting on something and not raised for an extended period.
