augmented reality (AR)

A technology that replicates, enhances or overlays extra information about the real-world environment, using computer-generated data such as global positioning systems (GPS), sound, videos and images. Common examples include a car windshield with a heads-up display (HUD) that projects three-dimensional navigation information and virtual lanes, or a swimming telecast using a line to indicate the position of the record holder in relation to the actual swimmers in the race.
