Layar Reality Browser

The Layar Reality Browser shows what is around you by displaying real time digital information on top of the real world as seen through the camera of your mobile phone. This technology is called Augmented Reality. We augment the real world as seen through your mobile phone, based on your location.
How does Layar’s Augmented Reality work?
The idea is simple: Layar works by using a combination of the mobile phone’s camera, compass and GPS data to identify the user’s location and field of view, retrieve data based on those geographical coordinates, and overlay that data over the camera view.
