"Multipoint" on singlepoint screens

A German genius called Jörn Loviscach at Hochscule Bremen has thought of a way to hack a screen that was only intended for single point interaction, so that you can use the "pinch-technique" (where you use your thumb and index finger to zoom in and out in Apple's iPhone) More about how you do this and what the limitations are in his paper: Two-finger input with a standard touch screen, published at UIST 2007, and available at ACM Digital Library. I especially like the rotary knobs at the end.
