Sparkfun.com made an AVR based USB Touchscreen Mouse, basically you attach a resistive touch screen to AVR IO pins and get the x and y coordinates with some calculations, after that sent to your computer using serial or usb port. So you will have a touch screen mouse or drawing pad. They used a PSP touch screen which also ready @ sparkfun store, the tutorial is very detail and clear, codes are included too, thanks guy who sent in.
