On December 20, 2012, the US Patent & Trademark Office published a patent application from Apple titled "Haptic Feedback Device." In the last eighteen months, Apple has worked on projects involving smart haptics and integrating a haptics layer into future devices so as to provide users with a greater sense of texture to their multitouch displays. Today's invention describes Apple's goal of creating virtual buttons that will feel like actual physical buttons to the touch and more importantly, having keys of virtual keyboards feel more like physical keys. As Apple describes it, they want the "user to feel as though the keys had been depressed." Considering that Apple lists "a keyboard of a computer and a track pad for a laptop," we see that Apple is thinking of adding haptics to devices beyond the iPhone and/or iPad. Apple revealed some rather elaborate work on this theme last September.
