Microsoft's hardware division has always pushed the envelope, and its latest prototype is no exception: this pressure-sensitive keyboard looks exactly like a normal 'board, but each key can register up to eight levels of pressure, opening up all kinds of interesting possibilities. Sure, there's a gaming demo, where pushing buttons harder makes you run faster or jump higher, but that's sort of old hat -- we're super intrigued by the typing corrector, which uses the pressure difference between keys you mean to type and keys you accidentally graze to fix your mistakes. Definitely interesting stuff, and we're sure to see more novel uses in October when Microsoft opens its first Student Innovation Contest by showcasing student projects made using keyboard prototypes. Videos after the break!
