For you home-brewers out there, there are a number of relatively
inexpensive (and untapped) markerless tracking sensors ready to be
incorporated. We use both linear and rotational (gyro) accelerometers
for position and attitude tracking.

Check out Crossbow's 1, 2, or 3 linear accelerometers (compliments of
the auto air-bag industry) at

	www.xbow.com

and my favorite, a two-axis rotational gyro, with built in integration
(for angle output) and RS232 out for only $70US!!  (a little hacking
required).  Checkout

	www.gyration.com  (a gyro based mouse)

Hope these inspire the creative hackers out there.
