Feb 03, 2016 · We'll physically extract the IR camera from the Wii remote and interface it with an arduino controlling a servo. The Wii IR camera is a beautiful thing. It has an integrated processor which outputs the X and Y positions and size of the 4 brightest IR points that is sees. This can be very useful for tracking in robotics or human interfaces. In 2007, Johnny Chung Lee invented the Wiimote whiteboard. As Lee explained in his runaway YouTube video, every Wiimote has a high-resolution IR camera. To turn it into a mouse or an interactive whiteboard, we connect it to a computer, fix it in one place, and use movable IR pens within view of its camera.
