Microsoft Research has posted a report, as well as the video above, about their prototype for a new, gesture-reading, mechanical keyboard. The prototype, built using the keys of an Apple wireless keyboard (oh, irony, sweet sweet irony), uses a low-resolution matrix of infrared sensors placed between the keys to detect gestures, such as swiping and pinch-to-zoom, on the keyboard.

This achieves an effect similar to the new Touch Cover 2 for the Surface 2 tablets, though the prototype goes a step further, reading gestures taking place above the keyboard instead of sensing you brushing your fingers over its surface.
