It seems Apple is working hard on developing a new generation input interface. The new patent pertains to something called “multi-touch input surface” and is a step forward (or a few steps forward) from the existing solutions, implemented on iPhone for example.

There’s a lot of technical details involved, but basically it comes down to improved ergonomics. The new interface will allow multiple ways for users to use it - finger touch and stylus (pen) - but without having to make all the excess hand, arm and body movement that inherently leads to fatigue injuries over time. It will “provide tactile key or hand position feedback without impeding hand resting on the surface or smooth, accurate sliding across the surface.”

See in more detail on Apple Insider.
