Connecting the remote touchpad to the Android system

I am going to connect a remote touchpad to an Android system (via infrared, bluetooth ...) for tablets or phones for example. But I don't know if it is possible to change the Android system for this, or if there are already systems using this concept. I've seen articles about using the Android screen as a touchpad, but what I want to do is the other way around: use the touchpad to move the mouse cursor to the Android system.

Thank you for your time!
