So, what exactly is AR?
Wikipedia defines AR as a live direct or indirect view of a physical real-world environment whose elements are augmented by virtual computer-generated sensory input such as sound or graphics. Simply speaking, AR is the ability to overlay location data points on the live view of a mobile device’s camera.Thus, AR applications combine virtual data into the real world by utilizing the phone’s compass, camera, and GPS system.
