The Wiimote sees IR light because the Wiimote is actually a camera.
The motion sensor bar placed on top or below your TV actually emits 6 (3 on each side) IR lights. The wiimote then makes a cursor (on the Wii) figuring where those points are according to how/ what angle it sees the points.

For the wiimote whiteboard the Program asks that the person do a 4-point calibration, showing the IR light to the wiimote on the boundaries of the screen. Then as a camera it knows where the point is.
You Might actually do this technique with a different camera, but the wiimote is the best camera for it's price.

The wiimote is connected to the Wii via bluetooth. Since bluetooth adapters allow computers to connect to bluetooth devices you can hook up to the wiimote.

Thank you JesseHNTR, your information was of great help. Now, you told me that wii remote has a camera, but How wii remote or this camera knows where is located a clik (for example.-recyler bin). What happend if I make a clik out of screen?.


Enclosure my email for are in touch. [email protected]

This is the same paragraph but in spanish, just in case.

 Gracias JesseHNTR, tu información me sirvió mucho. Ahora bien, me dijiste que wl wii remote tiene una cámara, pero cómo es que el wii remote sabe donde se dió un clik (por ejemplo- papelera de reciclaje). También, que pasa si hago un click fuera de la pantalla?.

Before you start using your setup you have to calibrate the screen - same procedure when you calibrate a PDA or smartphone - by clicking each corner(or lighting your irpen in this case)

Uwe Schmidt http://www.uweschmidt.org/wiimote-whiteboard has made a Java program.  It's pretty darn good, too.  I'd ask him.
