Augmented reality (AR) is a live direct or indirect view of a physical, real-world environment whose elements are ''augmented'' (or supplemented) by computer-generated sensory input such as sound, video, graphics or GPS data. It is related to a more general concept called mediated reality, in which a view of reality is modified (possibly even diminished rather than augmented) by a computer. As a result, the technology functions by enhancing one’s current perception of reality.〔Graham, M., Zook, M., and Boulton, A. ("Augmented reality in urban places: contested content and the duplicity of code." ) Transactions of the Institute of British Geographers, DOI: 10.1111/j.1475-5661.2012.00539.x 2012.〕 By contrast, virtual reality replaces the real world with a simulated one.〔Steuer, Jonathan. (Defining Virtual Reality: Dimensions Determining Telepresence ), Department of Communication, Stanford University. 15 October 1993.〕〔(Introducing Virtual Environments ) National Center for Supercomputing Applications, University of Illinois.〕 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.〔Chen, Brian X. (If You’re Not Seeing Data, You’re Not Seeing ), ''Wired'', 25 August 2009.〕〔Maxwell, Kerry. (Augmented Reality ), ''Macmillan Dictionary Buzzword''.〕〔(Augmented reality-Everything about AR ), ''Augmented Reality On''.〕〔Azuma, Ronald. (''A Survey of Augmented Reality'' ) Presence: Teleoperators and Virtual Environments, pp. 355–385, August 1997.〕〔Zhanpeng, H.,Pan H., et al. (Mobile augmented reality survey: a bottom-up approach ).〕 == Technology ==
