ABSTRACT
This chapter examines augmented reality (AR), in which digital technologies complement the senses in real time (unlike virtual reality, which replaces the real world with a digitized immersive environment). It illustrates the characteristics of augmented technologies in detail and their evolution over time, using copious illustrations. From head-mounted displays to smartphones, today vast numbers of people have access to this technology. The chapter also notes the applications of AR in multiple contexts, including architecture, health care, marketing, and entertainment.
