Sony’s patent application for a haptic touchscreen composed of “tactile pixels” shows former Sony Computer Entertainment chief Phil Harrison as the inventor. It also has a bunch of references to potential use in “a game device” and to “game events,” so it seems fairly obvious that it was developed as an idea for PSP.

The patent app describes a haptic feedback system that seems pretty complicated. The pixels themselves are capable of moving up and down, providing feedback to user actions. It’s certainly interesting, but we’re not gonna hold our breath waiting for this to hit the consumer market anytime soon. We wouldn’t mind being wrong though.
