How about a rate gyro? The following should give you some insight.

I was going to suggest a roll sensor turned sideways. ;-)

2 + 2 = 5 for extremely large values of 2.
I am looking for a sensor that can detect motion on all 3 axis, and send
it to a regular pc.

Thanks,

Are the specs still evolving or don't you know what to ask for? You might
also indicate what your budget might be for this lest someone recommend
parts that would normally be used in an inertial guidance system
(expensive). What is the intended use?
This is starting to scare me... I'm done.

It is an evolving design. I want to make something that a person would wear,
and this would track the motion. If you know of a simpler, cheaper idea, I
am open to suggestions. The cheaper the better. I also want to make as much
of it as I can, hence the request for schematics.

Thanks,

GPS in track mode.

A worthwile 3 axis rate gyro is very
expensive, and rather inaccurate, the
output needs integrating, and becomes
inaccurate in a hurry.
We tried it in the ISS on an astronaut.
