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.
(TNO TM , Netherlands, link
http://www.esa.int/esaCP/SEMEUM57ESD_Netherlands_0.html
)

it would be used inside the confines of a room. It would be wired to a
computer. I dont need to know where it is, I just need to know that it moved
that way.

How much is concidered expencive?

Thanks,

Micheal
