The Leap Motion controller is here at last, and almost inevitably, it does not live up to the hype - yet. The beauty of these types of hardware and software driven devices is that the software can be improved. The promise was of an accurate method of using gestures to control computer application, simply by moving your hands or fingers in mid-air; no mouse or trackball needed - reminiscent of computer interfaces like those in the movie Minority Report. Doesn't the XBox Kinect controller do that already? Yes, but it's a game-based controller and the control is less precise; Leap Motion is supposed to be suitable for use with computer apps - although based upon initial reviews, they may have some work to do. Still, it's finally here, so let's see where we go from here.
