Everyone loves multitouch on touchscreen phones and trackpads. But what about on a desktop?
A group of Microsoft researchers has built a kind of multitouch for the conventional keyboard, and it looks to be even more useful than the iterations we know on the iPhone. It allows a keyboard to accept pressure-sensitivity data, from which it can infer user intentions. The innovation has terrific potential for gaming--the harder you press spacebar, the more bullets you shoot in a first-person shooter--but also for social networking and word processing. As the video below demonstrates, it can be used to infer typos, adjust font styles, and size for emphasis.
