We struck an interesting issue this week. One of the schools that have sourced equipment through 3Pi reported that they couldn't get the system to work in one of their classrooms.
The classroom setup was unusal in that the projected image was quite high (above the floor).
They had been trying to calibrate from desk height aiming the wiimote up, but it just wouldn't calibrate.
When we looked upwards along the top of the wiimote, to the middle of the screen, there was an incredibly bright reflection. It seems that the combination of a steeper than usual upwards angle and a very reflective screen were confusing the wiimotes camera. When we tried the wiimote positioned at double the height, it calibrated perfectly, as it also did when we positioned it up by the projector looking down. (Another issue for such a high setup is that only very tall people could interact with the image anyway - not good for young students!)
