Augmented reality (AR) is a live view of a physical, real-world environment whose elements are augmented (or supplemented) by computer-generated sensory input such as sound, video, or graphics. The technology functions by enhancing one’s current perception of reality.
Augmentation is conventionally in real-time and in semantic context with environmental elements, such as sports scores on TV during a match. With the help of advanced AR technology (e.g. adding computer vision and object recognition) the information about the surrounding real world of the user becomes interactive and digitally manipulable. Artificial information about the environment and its objects can be overlaid on the real world.
