... means:
▶ The disappearing computer: from fixed to mobile to wearable
▶ It is about the Computer in the World and NOT the World in the Computer : bridging the gap between virtual and real world
▶ Context- and location-aware, diverse and numerous, human-centric
▶ Smart devices with spontaneous network capabilities that have access to any information or provide access to any service “on the net”
▶ Vision: everyday objects become smart and interconnected; they communicate and cooperate
▶ Much technology driven: Moore’s law

Ubiquitous computing
◆ Mark Weiser (1988) : Ubiquitous means “to be found everywhere”
◆ The Any notion : anywhere, anytime, any device, any person, any application
◆ The disappearing computer : Computer weave themselves into the fabric of everyday life until they are undistinguishable from it (Weiser)

Mark Weiser : Ubiquitous Computing
◆ Mark Weiser’s (1991) vision : a vast amount of interconnected computers lying around and embedded everywhere
◆ “The Computer for the 21st Century”, published in Scientific American
◆ ”The most profound technologies are those that disappear.”
◆ “There is more information available at our fingertips during a walk in the woods than in any computer system, yet people find a walk among trees relaxing and computers frustrating. Machines that fit the human environment, instead of forcing humans to enter theirs, will make using a computer as refreshing as taking a walk in the woods”

Mark Weiser : Ubiquitous Computing
◆ What’s his main message?
► Conceived of a new way of thinking about computers
► “Not just computers that can be carried to the beach, jungle or airport”
► Technologies disappear into the natural human environment
► Computers are seamlessly integrated into the world at large
