I'm looking for a sensor that would return its position on 3 axis in a small range (2 ft x 2 ft x 2ft).

I'd like this to be connected to an output mapping system, in order to control the diffusion of sound through a system of 24 loudspeakers.

I won't have any problem with doing a patch to manage this, but I really don't know where to find such a sensor. 

I've heard that by combining a gyrometre and an accelerometer, you can get a position... is it true? Does anybody know any other sensor that would do this with precision, maybe a GPS???

Wetterberg : Does the Gametrak calcultes the position by itself or would I have to do a patch that evaluate it by getting some other data from the controller? 

It seems interesting, though it doesn't seem available neither in Canada nor in United States, and since I don't care about having a cable or not, I'd be happy getting one of the older ones.

It's sad that the Wii controller doesn't give the position... I managed to get the orientation of the controller by analysing the accelerometer data, but nothing near a position detection system...

Maybe there is some hope with the Wii MotionPlus?

You can do x-y-z position tracking fairly easily with two cameras in a

controlled environment which it sounds like you are aiming for.

just use a precisely coloured ball or something to track and the rest is

You can do x-y-z position tracking fairly easily with two cameras in a
controlled environment which it sounds like you are aiming for.

just use a precisely coloured ball or something to track and the rest is
done in max.
