""Multitouch on a resistive screen?" We must be joking, right? Not at all -- if we've learned anything from our encounters with a little firm named Stantum, resistive multitouch is not only possible, but potentially preferable to its capacitive counterpart. Of course, that knowledge doesn't help you any if you're currently stuck with single finger commands, but if your phone is made by HTC and running Windows Mobile, you may one day get to see what two digit input feels like. Adel Al Zubeir figured out that when two fingers are placed on a single-touch screen, the digitizer reads the spot between the two... and with a little bit of math, he cooked up a program that can figure out the relative position of both fingers to allow vaguely useful pinch-to-zoom and other dual-touch gestures."
You know what the sad part of this post is? The following 3 words: "Proof of concept". So yes, pseudo-multitouch is possible on Windows Mobile. But each and every one of your favorite software apps would need to enable it for you to be able to use it.
