Samsung has filed a patent for a phone that is operated with only your hands, but not on the phone. The idea is that you move you hand around and form gestures in the air to control the phone. The patent states that the hand movements would be captured in the phones camera and then translated into instructions for the phone.
As interesting as this technology is, it is only a patent, so who knows when, if ever, we we’ll see products using this on the market.
