An anonymous reader writes "A startup named Mgestyk Technologies claims that they have an affordable solution for 'Minority Report'-like PC control. They have released a video in which they use hand gestures to play games like Halo and Guitar Hero, as well as perform 'multi-touch' interactions for applications like Google Earth. Engadget and Gizmodo discuss the potential of the technology but point out that the system has visible lag when used for gaming. Will camera-based interfaces ever meet the low-latency demands of gaming? For how much longer will we still be using keyboards, mice and joysticks?"
