As I have thought about the pen concept further, I have wondered if placement of the IR led in the rear of the pen would be the way for the wii remote to track best...at least if pointed from directly behind. I am going to put together just such a pen soon to try it out.

This idea has been tried i think, but it probably won't work, since the angle of the pen changes the position of the IR led, so your mouse will be at another position.

It would require placement of the wii remote directly behind and perhaps elevated like a digital projector and would require the user to not use wrist movements but movement of the hand. I say this as I use dry erase whiteboards quite often as a teacher and use of the wrist is quite minimal and seeing as how the pen is simply a replacement for the mouse, an adult should be able to keep his/her wrist pretty stiff. Like I said I am going to try it.

I am thinking about how I always wrote on the white board when I was teaching.  Hand and wrist relaxed and in neutral position, not much movement there because of (1) the mostly large strokes being made so that everything is visible to students in the back of the room, and (2) babying the tendonitis in my hand and wrist.  Most movement was in the shoulder and elbow.  But every now and then, the angle of the pen to the board would vary more if I stretched or leaned over to write something at a difficult to reach part of the board, and occasionally I would have to contort myself to face the class while simultaneously writing.  I have seen another teacher habitually flip the marker around backwards in her hand to write and face the class at the same time. 

Analyze your own current habits.  If your hand and wrist are usually in a stable position, it may work.  If you use a lot of wrist movements, or vary the way you hold a marker, you'll probably have trouble with it. 

Either way, I can't imagine that it would work well if you ever plan on handing over such a pen to your students, because they won't hold it the same way that you do.  Goodness, half of them lean their oily hands on the white board and try to write with the marker as if it is a pencil. (shudder)
