The folks at ETH Zurich’s Flying Machine Arena are using Kinect gesture input to control quadrocopters fly around the room with only hand gestures. The little four-rotor helicopter’s remote control is hooked up to a Kinect Xbox controller and the controller’s cameras are mounted above the user to give it a top-down view of the user’s gestures.
Hold your right hand out, and the quadrocopter hovers a set distance away from you in line with your head and hand. Sweep your right hand, and the quadrocopter moves in the direction your hand’s moving. Hold your left hand over your head, and the quadrocopter does a loop. Clap, and the quadrocopter lands. It looks amazing in action and you can check it out below:
