does anyone have experience in using 9 DOF sensor

I am doing an FYP project which write an application to track human motion.
But I don't hv clue what sensor should i use, could anyone advice some?

It could be great if the sensor contains wireless function for data transmission or it can be plugged in with a wireless device....

Thanks all you guys~

What does FYP project mean? What you're asking is no simple task, three is no 'one' sensor that can do what you ask, you need a complex network of sensors, if you could state your SPECIFIC goals instead of the impossible general question you originally asked practicality might be a little more achievable =)
