known as "embodied virtuality". 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. See Mark
Weiser, "The Computer for the 21st Century" Scientific American
