At one of the talks today at MIX11, the focus was Natural User Interfaces (NUI) and their future. A lot of the talk was philosophical but there were also some cool demos of things not yet seen.
One of them was the use of a Surface 2.0 interface for a hover drone. Sure it has nothing to do with Windows Phones, but we're suckers for awesome gadgetry. Basically the Surface became the controller and it worked quite well. Next, was perhaps even cooler as the same hover drone was controlled via full body motion with the Kinect SDK. While perhaps not very practical, it goes to show how powerful NUI can be even for awesome remote controlled helicopter thingys. Sorry about the volume, can't help those things. (And yes, we want to be Jedis)
