The phone camera(s), the G-sensor, the compass and so on will be used by a software to understand the gestures and to translate them into control commands. This breakthrough comes from a company called GestureTek, a non-startup company in this field." I love the idea of my screen no longer being smudged. I hate the idea of people doing this on a bus.
