Wiimote and 3D world

Hello, I have a question about how to use the Wiimote in a 3d environment, I want to do is move a camera in the xy position, according to the xy position wimote.The problem is how to adjust the position of the wiimote for a scenario of (for example) 10x10 px of diameter.

Does anyone know how to fix this?

thanks ;)

XY is 2d. you need X,Y,and Z for 3d. I havent checked in libogc yet, but i assume that you would use the Z the same that you would use X and Y.
