This video was posted on Twitter by @keiichiban who is working at Leap Motion designing UI solutions for augmented reality.
He was using Leap Motion’s new north star AR HMD with 180 by 180 FOV for hand tracking. The company is releasing the HMD to developers but what they really want is for their technology to be built into existing HMD’s.
I hope their vision takes off. For more info research Leap Motion company.
