ubiquitous computing
Computers everywhere. Making many computers available
throughout the physical environment, while making them
effectively invisible to the user. Ubiquitous computing is
held by some to be the Third Wave of computing. The First
Wave was many people per computer, the Second Wave was one
person per computer. The Third Wave will be many computers
per person. Three key technical issues are: power
consumption, user interface, and wireless connectivity.
The idea of ubiquitous computing as invisible computation was
first articulated by Mark Weiser in 1988 at the Computer
Science Lab at {Xerox PARC}.
