It's probably capacitive. There are a few different technologies for 
touch pads. Some use the capacitance of a human finger (and won't work 
with a plastic stylus). Others use pressure itself, and will work with 
pretty much anything (this is how most touchscreens in PDAs and the like 
work). Others use a magnetic or RF system and use styli and/or mice with 
electronics in them (Wacom does this).

If it's a capacitive design, you'll have to figure out a way of 
emulating a human finger.
