I want to connect a handsfree mouse, i.e., a head control mouse, specific brands include madentec Tracker Pro, Origin Headmouse Extreme or a Smartnav to an ipad for people with physical disabilities who cannot use their hands. The devices are "plug n play" via USB, i.e. , no software required to run the mouse, but software is required for "mouse clicks", such as dwell click, or for windows versions Magic Cursor, Click n Type, etc. Is this possible? what do we need to do this?
