Introduction: Augmented reality (AR) augments our physical world by combining it with a layer of digital information. Using an AR application gives you a view of the physical world superimposed with computer-generated 3D objects. For example, you can use AR to see how a piece of furniture would look in your room before buying it, or to play a game that uses your surroundings as part of the gameplay. AR can also provide additional information about your environment, such as directions, reviews or historical facts.
