Make a MultiTouch Screen with Wiimote

We will need 3 materials and 1 software.
Materials;

1. Bluetooth: I have used Billionton and no problem happened.
2. Wiimote: We all know what it is.
3. Infrared pen: I took an infrared led from an old Music System remote control and its battery. Give a shape like pen.

Software: You can download it from here.

Set the bluetooth to your computer and connect your Wiimote via bluetooth. Use BlueSoleil software it is useful. And run the software which you downloaded , track corners of your screen with infrared pen. And start using a MultiTouch screen .

Here is a forum to discuss the problems.
