The engineers who invented the touch screen has done more for the field of usability than any UX or usability expert could ever hope for. Which is interesting in itself because for the first 30-odd years of touchscreens they were largely a usability nightmare for anything more complex than simple multiple-choice buttons (and even then, often sub-par.) Partially due to technological limitations (low-res resistive screens), but partially because traditional interface abstractions don't translate at all well. It took clever UX engineering around touchscreens for them to get past the gimmick factor and become useful and immersive mainstream computing interfaces.
