I had tested this with the Apple Remote as the IR pen on an LCD screen and it worked well.
I then to the Mac Mini to one of our conference rooms and tested it with a projector onto a whiteboard. I had a bit of trouble getting the Wiimote placed so that:
1) The entire screen was recognized. and 2) The Wiimote was not too far away to “see” the IR source.
Once I found the right place for the Wiimote, it worked well.
I’m not ready to roll this out to all of our classrooms. (Not sure I could get that many Wiimotes:) But I am ready to test it with one of our teachers.
I may try the IR pen that I made. I suspect that the IR LED in my pen is a bit stronger than what is in the Apple remote. (I used the same LEDs that Johnny used in his demos.)
Exciting times.
