Gesture controls are very common today with the iPhone really putting gesture control on the map when it launched in 2007. Today you can control all manner of smartphones and computers using gestures like swiping to change pages or scroll and much more. The catch with touchscreen gesture control is that you have to have the device in hand to use the gestures.
TI and Extreme Reality have teamed up on next-generation gesture control tech that allows the user to control a device without actually touching the screen. The new tech can even allow the user to control a smartphone or other device from across the room. The tech uses a front mounted camera to sense the gestures and turn them into commands.
