I am thinking of connecting a remote touchpad to an android system (via infrared, bluetooth ...), for example for tablets or phones. But I don't know if it is possible to edit Android system in order to do that, or if there are already systems using the concept. I have seen articles talking about using android screen as a touchpad, but what I want to do is the opposite : using a touchpad to move a mouse cursor in an android system.
Thank you for your time !
