| TWRoO said: 6D? what are you on about. by the way the sensor bar has 10 LEDs ... and although they only act as 2 points of reference, it can still however track almost any movements that a 3 point triangulation could because it knows the distance between the two points.

There is a good reason why TrackIR uses three points of reference to track 6D movement (one point set back from the other two.)I beleive you knew I wasn't referring to have many led light the wii actually uses but how many points it uses which would at least required 3 LED lights to do 6D movement.
With two point reference there are two way to make the two points closer together from the camera viewpoint, the first it to move farther from the camera and the secord is to turn your head a little to the right or left. With 3 points of reference the camera can tell the difference between head movement from head 3D position. Thus wii head tracking would be limited for the most part 2D movement.
