Mouse data output from Arduino

I'm currently developing some alternative input devices, for artistic purposes mainly but also with the possibility of them moving more into a therapeutic context. They involve using the knee and elbow joints to control cursor position. I've got a basic prototype working by doing an analogue read on two variable resistors then using the arduino to interface with a basic drawing program in processing. the problem is it only works in the window that processing creates.

for the info on my setup thus far-

So i'm thinking I need to send data out of the arduino and have that data recognised as mouse data by my PC, that way my multi-limb input devices can function as a mouse and not just a processing exercise.

my coding is at a very basic level so any tips are most appreciated.

You will have to look up the PS/2 protocol. But maybe this is a nice start:
Arduino Playground - Ps2mouse I know that this is the other way around, but it might be usefull to learn the protocol.
