“It seems like a paradox but it will soon become reality: The rate at which computers disappear will be matched by the rate at which information technology will increasingly permeate our environment and determine our lives. This notion of the ‘disappearing computer’ is one of the starting points that determines our work. Another one is the shift from information worlds to experience worlds. This was a consequence of our work on innovative office environments where we explored the range of social processes that should be supported with information technology and the shift to a new application domain, i.e. games and entertainment in the context of home environments.” (Norbert Streitz et al. – uigarden)
