I saw this on the news for upcoming consumer technology in 2013 reminiscent of Minority Report when Tom Cruise was navigating his computer by just waving in the air. Its available for preorder now from their website. There might be some interest here in the community. Seems mighty nifty. This is not as bulky as the Kinetic. They market it as the size of an ipod and can perform fine motions such as digital signatures.
