Google's Maps app has got a new augmented reality or "Live View" feature, which should help solve a persistent annoyance: knowing which way to head when you're following directions.
You know the drill: a blue dot appears on the map on your smartphone's screen - but it's often hard to tell which way you're supposed to head.
In theory, your phone should be able to indicate the right direction, but in practice - especially when you're in a CBD - the GPS signal bounces of buildings and constantly chops and changes your orientation.
And while most phones also have a built-in compass, in a downtown environment you have to constantly do the whirl-it-in-a-figure-8 thing to reset it - which is a pain, and makes you look silly.
Google says, Tall buildings can interfere with the accuracy of online maps.
