Apple adding augmented reality to iOS (IPhone & IPad) maps

A recent patent submission by Apple describes a technique to improve iOS (IPhone & iPad) maps using augmented reality. It proposes to integrate additional information by overlaying a camera video stream with supplemental information about the surrounding environment.

This approach seems to be very close to techniques used already by Layar or Wikitude. I'm really curious how Apple will implement this approach in a final product. Yet it remains unclear where in which way this technique is innovative!

"According to Apple's patent application, street names, addresses and landmarks can all be added to a scene simply by pointing the camera at an area in the vicinity."
