I thought to think up a way to make a touch screen that you didn't have to clean constantly because you actually <gasp> touched it, by using the the inverse square law of magnetism to tell the screen how far your finger was from it but ... stick a tooth pick in and see if it comes out clean because it's dang near baked.

Give it the finger, ... er not.

Theremin Touchscreen?

It's a don't-touchscreen.

I remember seeing a tablet PC about 7 years ago, the touch interface was driven by a pen; the pointer on the screen followed the tip of the pen around if the pen was within a couple of cm of the screen, and actually touching the pen to the screen registered as a click. I liked it but could not afford to buy one <weeps into secondhand keyboard where all the characters have rubbed off>.
