Ubiquitous computing Pervasive computing Invisible computing(Weiser, 1991) •Combination of mobile computing (use of (Norman, 1998; Borriello, 2000) computers worn on or carried by users) and•Collective use of computers available in the computers embedded in the fixed environment. •The use of computers in such a way that the task physical environment of users, perhaps is focused on and facilitated, without too much embedded in a form invisible to users; thus focus on the tool (i.e., the computer system) putting computers out into everyday living itself. environments, instead of representing the everyday living environment in the computer.Disappearing Computer Proactive computing Autonomic computing(European Union Initiative) (Tennenhouse, 2000) (Horn, 2001)•Artifacts commonly seen or used in everyday life •Computers anticipating user needs and taking •Systems that can self-monitor, self-heal, and with computational capabilities (using some action on users’ behalf.

It also looks at people’s experiences with environments comprised of such artifacts.
