"Samsung has patented a system of cellphone and mobile device control that responds to a users gestures, not on the screen as with the multitouch iPhone but as recognised in the space around the handset. Using the cellphone’s front-mounted camera, the software recognises preset motions and translates them into on-screen control. For instance, pointing at the screen and then moving the finger could control a mouse or cursor, while rotating the wrist with the hand outstretched might flip an image or layer."
