Couple a lack of a keyboard and mouse with the lack of real estate in most mobile devices and you have a brand new problem with ergonomics and accessibility. Apple broke in the door with multi touch sensors that allow the screen to pinch and zoom with two fingers. The ability to recognize how your fingers interact with the screen means more intuitive gersture commands opening the door to far more access to tools and usage paths. This vide demonstares the ability for this phone to recognize what part of hand is tapping the screen. The result: your fingernail tapping the screen equals a right click, and a knuckle tab opens a new window.
