I don't think I explained the difference between the 2 versions very
well. First think about all the ways you can move your head or
anything for that mater. There are 6 degrees of freedom. You can move
in x, y or z. That is 3 degrees of freedom. You can rotate about the x
y and Z axis. That is the other 3. The basic tracker assumes you only
have 2 degrees of freedom, rotation about the Z and Y axis. That is
with the Z axis being vertical and the Y axis going from left to right.
In aviation terminology this corresponds to yaw and pitch
respectively. Obviously even with the low end 2 axis version you can
still move your head in any way you want, but the device just senses the
movement of the little silver dot it is looking at, and assumes the
movement is caused by rotation about Z or Y and moves the game head in
that way.



But when you rotate your head in any direction, you turn your gaze
from the screen (unless you rotate your eyes to compensate). So how
do you see the updated display? The Track IR seems to be just a
tracking device, not a display device.

That is why it exaggerates your head movements. You rotate your head
just a little, and the game head rotates a long way. You never are
looking very far off the center of the monitor. For me the farthest I
rotate my head, is so my head is pointing to the edge of my monitor.
That way I don't need to move my eyes very far at all to keep them on
the center of the screen. It is amazingly natural. If you try it, you
will never go back to not using it. It really is that good.
