ABSTRACT
Virtual reality (VR) can mean different things to different people. The term “virtual reality” was coined by Jaron Lanier in 1987 during a period of intense research activity into this form of technology. In virtual worlds, computer-simulated environments host avatars, which are digital representations of a specific person. The avatar can manipulate objects and participate in day-to-day activities that most people take for granted, such as walking, dancing, and communicating. The term “augmented reality” (AR) was coined by Boeing researcher Thomas Caudell in 1990. He used the term in relation to the industrial use of AR at Boeing. Since 1990 different industries have been involved in research and the development of AR. AR became a more familiar term for the general public during the Pokemon GO craze in 2016 when a re-imagined a mid-1990s computer game was launched as an AR app that allowed users to catch digital creatures in real locations.
