Chaotic Moons Labs is showing a 30 mph motorized longboard controlled by the use of Kinect and a Samsung Windows 8 tablet at CES 2012. Being the chiefs of tact, this device has been given the name of the "Board of Awesomeness."
Using a combination of video, voice, accelerometers, location data and gestures, the board reads the rider's physical movements as control intentions to process and transmit the data via the tablet, then moves accordingly as you can see in the video. We particularly like the process of starting to move: waving your hands at the kinect and seeing red dots on your hand to represent the points of movement.
