Johnny Lee strikes again. The Wiimote Guru has a new project. Build your own expensive looking smartboard using a projector, laptop and a Wiimote. Excellent little project to kick off the new year.
Since the Wiimote can track sources of infrared (IR) light, you can track pens that have an IR led in the tip. By pointing a wiimote at a projection screen or LCD display, you can create very low-cost interactive whiteboards or tablet displays. Since the Wiimote can track upto 4 points, up to 4 pens can be used. It also works great with rear-projected displays.
