: Since the invention of the electronic computer in the 1940s, technological development has resulted in dramatically increased processing power, storage capacity and communication bandwidth physically embedded in devices ranging from large mainframe computers to tiny radio-frequency identification (RFID) tags. Toasters, blenders, elevators, cars and an increasing range of other everyday objects embed computer technology. Over 4.3 billion phone connections have placed processing power, storage and communication bandwidth directly in the hands of around half of the World's population and a range of emerging technologies is expanding this further. Weiser (1991) created a conceptual clearing characterising this phenomenon as ubiquitous computing. He argued that pervasive access to information will lead to a more harmonious relationship where computing adapt to the human environment instead of the opposite. However, large-scale mobilisation of interaction implies the risk of a less th...
