An anonymous reader writes "Microsoft has demoed a prototype gesture-controlled PC using an augmented version of its Kinect motion sensing system. The rig detects 16 gestures and can be used to navigate Windows 8. Microsoft said it wants gestures to complement what is possible using mouse and keyboard, rather than replacing them, and the system favors simple gestures made just above the keyboard, rather than more elaborate Minority Report-style gestures. '[A] window is maximized by clenching a fist to "grab" it and then opening the hand while moving towards the top of the keyboard. Performing the same series of gestures in reverse minimize the window. Repeating the gesture while moving the hand to the left or right edge of the keyboard docks the window with the left or right edge of the screen. The same series of gestures while moving the hand to the top left and right corners of the keyboard will throw the window to the left or right of screen, but not dock it with the edge. Bringing hands together in the middle of the keyboard and then moving them to the keyboard's left and right edge with palms down and fingers splayed will show the desktop. Repeating the gesture restores the original view.'"
