 So what we're showing here is going to be coming out with the next release of Kinect for Windows SDK and it augments the Kinect skeleton with a grip and release signal. So what you're seeing on the screen here are these cursors, they're representations of my hand. As I grip with my hands, it engages and now I can do things like pinch to zoom or pan around here. And I'm going to zoom in here on Cambridge, if I can find Cambridge, it's down here a bit. There it is, this is where we're based, MSR, Microsoft Research in Cambridge. And what we're doing here is we're using machine learning to learn how to recognize whether your hand is open or closed. So we've used a bunch of, we've recorded a bunch of training data from lots of different people using different, using the different open and closed gestures and trained up this system using machine learning so that it can recognize robustly whether your hand is open. And all we're doing here is injecting this open close signal into Windows so we can move things around and grip and release with our hands. So any app could be used, let's switch to a game now, this is going to be Jetpack Joyride and I'm just going to show, it's not quite switched. So I'm going to show here that I can just control a game, this is quite a simple control game but I can now play this game just by squeezing my fist. I can move the jetpack up and down and select the points.
