Israel-based company PointGrab revealed their new PointGrab AirTouch technology at CES 2014. Unlike other interactive gesture driven interface software like Kinect by Microsoft or Leap Motion, which require specialized hardware to play games and the like, The PointGrab AirTouch operates with 2D cameras.
PointGrab AirTouch allows the controller to point to icons on interfaces like they were pressing a button. The user can also grab and drag icons around the screen, pause DVR playback, choose a channel by writing it in the air in front of the screen, and even mute the setup by placing a finger to their lips. The motions don't need to be exaggerating either; subtle, natural movements are all that's needed to operate the system. The PointGrab AirTouch will revolutionize the way we watch TV
