Andrew M. sent us this link to a video showing off a wicked "multi-touch" screen. Instead of responding to just one poke at a time like today's touchscreens, a multi-touch display could process several touches at once. The ability would come in handy for a tabletop workstation where you might have several people working on it simultaneously. And for individuals, a multi-touch screen could let a person use one hand to rotate a map while using the other as an anchor point (this scenario, and a few other cool ones, are shown in the video). The screen's just a prototype right now, one of several high-tech projects in the charge of Jefferson Y. Han, a self-described consultant at New York University. Check out the Holodust video for some more sweet future tech.
