360 degree Headtracking, which hardware?

[Morphes]

What would I use to do 360 degree head tracking through a computer interface, I heard of some people doing it with a ps3 controller but I couldn't really find out how to do it. A lot of people use wiimotes but from what I could tell, they only work with the IR sensors which would prevent 360 degree movement.

Anyway I did a brief search but couldn't find anything, so sorry if its a repost. Also feel free to move the post as I wasn't sure where to post it.
