In my last post I dis-organised a few things, so .....

I would like information on current 6DOF tracking technology.

	Weight of head device.
	Maximum angle of Roll, Pitch and Yaw.
	Maximum updates per second / speed of response to user changes
	Working volume of tracking
	Power and voltage requirements
	How noisy a working environment can be before the device malfunctions
	Free space or not.

Free space means that a user is not tied-to a specific location.
eg, if a tracker needs a wire connection from the helmet to the computer,
    it is not free-space.
    However, if the tracker has wireless operation, then it can be considered
    for this information as free-space.

Thank you
