Augmented reality is defined as augmenting an image of the real world with a computer-generated image that provides additional information. After introducing the basic definitions, the chapter covers the challenge of modeling the real environment. This process generally has two phases: sensing the information from the environment using various sensors, then reconstructing the environment. The chapter also describes the specific displays and user interfaces used in augmented reality. It concludes with a few representative applications, from medicine to advertising.
