Using an external touchscreen to INPUT to iPad?
So I was wondering if this has been done or is even possible. I would like to attach a secondary touchscreen display to my ipad that would allow me to control the ipad via a secondary touchscreen. The ipad & secondary display would be in "mirror" mode so they would display the exact same thing just allowing me to control it externally. I want to put an ipad in my vehicle but I would like to be able to permanently mount the touchscreen then just have a cable that goes to the ipad so I could keep it in the console or glovebox. This would make mounting in the vehicle much simpler since you would not have to make a intricate mount that allows the ipad to be removed. Is this possible?
