I would go with the touch screen overlay. There are interfaces out there that will allow you to connect a resitive touch screen to the USB port of your car-puter and it reports touches as x,y locations with mouse click.

I would steer clear of capacative touch screens as they are subject to noise, however resitive touch screens are subject to heat problems causing calibration to drift. If you get a good quality touch I/F then the auto calibration should be taken care of.
