Weak Signal's description 
Concept of pervasive or ubiquitous computing, where information processing is thoroughly integrated into everyday objects and activities, is more than 20 years old. But current trends in the design of pervasive systems have concentrated on the provision of isolated smart spaces via a fixed infrastructure, which is likely to lead to the evolution of islands of pervasiveness separated by voids in which there is no support for pervasiveness. To the contrary, the vision developed in FP7 PERSIST project is of a Personal Smart Space which is able to provide pervasiveness and context awareness to a user everywhere and all the time. Personal Smart Spaces will be adaptable and capable of self-improvement and they will be capable of learning and reasoning about users, their intentions, preferences and context. This approach may leed to new quality of pervasive computing implemantation and subsequently to improving quality of everyday life.
