Apple recently applied for a patent for "movement-based interfaces for personal media devices," which means a more advanced accelerometer and movement gestures for the iPhone.
Following in the footsteps of Sony Ericsson, Apple doesn't seem to be satisfied with just the ability to switch between landscape and portrait orientations or simple screen-tilting in games. Just to name a couple of examples, with more gesture controls, you could switch between different webpages with a slight tilt, or change songs by shaking the gadget. That sounds pretty cool and all, but how will that work with my allergies? Sneeze or song change? Apple won't know. [Unwired View]
