Air Guitar + Kinect Hack = Pure Awesomeness

Thanks to Microsoft's XBOX 360 motion-detecting system, Kinect, the world is becoming a play place for sci-fi style virtual reality. One of the latest hacks demonstrates the next best thing to regular old air guitar... virtual reality air guitar:

Artist Chris O'Shea explains how it works:

"First it thresholds the scene to find a person, then uses a histogram to get the most likely depth of a person in the scene. Then any pixels closer than the person to the camera are possible hands. It also uses contour extremity finding on the person blob to look for hands in situations where your hand is at the same depth as your body. It only works if you are facing the camera front on. Then it uses one hand as the neck of the guitar, drawing a virtual line from the neck through the person centroid to create the guitar line. The other hand is tracked to see if it passes through this line, strumming the guitar. The neck hand position controls the chord."
