I just watched a virtual environment video from NASA (AMES?) and
they mention just slapping on one of their compact 6-axis
(x, y, z, roll, pitch, yaw) transducers - like on a dataglove.
I imagine it's a related or identical technology - go ask in
sci.virtual-worlds and I predict you'll get much better response.
I hear via the partially informed that they are expensive.  I think
the company which makes the sensors is mentioned in the video and is,
not surprisingly, located in Si valley.
