Browsing the web using gestures is no where close to what this hack can do. YouTube user Yankeyan has managed to use the motion sensing gadget to control Super Mario Bros 1,2 and 3 on a NES emulator.
Yankeyan programmed this with OpenKinect drivers and Nintendo emulation, so that Kinect recognized his motions and virtual button presses onto the emulator. “I could have placed a simulated keypad right in front of me that I can press with my hands, but I thought full body gestures were more in the spirit of Kinect,” he writes. “Of course, Mario isn’t designed to be played like this, so this is really really hard.”
