Augmented reality: It's a feature that's cropped up in plenty of apps, but it's always seemed a bit like a solution in search of a problem. Could an Apple-implemented augmented-reality option find a home in mapping? Rumors suggest that Apple is using a 3D-mapping technology that it picked up when it acquired C3 Technologies, but it's unclear exactly what the implementation might be. Perhaps it could be used to beef up turn-by-turn directions by showing real-world landmarks, or even provide points of interest like nearby restaurants, lodgings, or gas prices.
