Also known as "embodied virtuality". Information and early Interplanetary Age Old Earth. Computers that are an integral, invisible part of people's lives. In some ways the opposite of virtual reality, in which the user is absorbed into the computational world. With ubiquitous computing, computers take into account the human world rather than requiring humans to enter into the computer's methods of working. Ubiquitous computing evolved into the micro-, meso- and micro/meso/nanon based interactivity of the middle Interplanetary Age and later.
