Wikitude Drive is a satnav system that uses augmented reality to overlay a route on to a live video stream.
The company behind it has launched a beta version for testing that works worldwide. The software is compatible with Android based smartphones and allows the system to either use a live video stream, or 3D maps if you prefer.
Driving directions not only appear on screen, they are overlaid on the live video stream of the very street you are driving on. As a result, you are seeing the real world and real road in front of you, while being directed by a digital route on top of it.
