Description The vision of PERSIST is of a Personal Smart Space, which is associated with him/her...PERSIST joins current trends in the design of content-aware pervasive systems that aim the implementation of user-centric Personal Smart Spaces (PSS). These spaces are based on personal area networks and are constructed from a variety of networked components such as portable devices that can be easily carried around by users and provide content-aware pervasiveness anywhere and anytime.  What Personal Smart Spaces can do: • Personal Smart Spaces can link into pervasive infrastructures such us a surgery infrastructure for example. Consequently, personal data of patients, that own a PSS with incorporated sensors, can be uploaded and their medical records appended immediately. These in turn, will be easily accessible by the doctor's personalised PSS graphical interface. • PSS will be capable of pro-active behaviour and self-improvement. This means that they cater to users' needs and interoperate with each other. Interoperability is the key that will allow PSS to extend and enhance as users encounter other smart spaces in their every day life. They will automatically adapt new environments, learn and reason about users and their intentions but also resolve conflicts between the different preferences of multiple users. • On the basis of 'recommender systems', Personal Smart Spaces will provide recommendations, prioritise and share limited services and devices between users without however, neglecting the protection of privacy. PSS will also be sufficiently fault-tolerant in order to guarantee their own robustness and dependability. • Another vision of PERSIST is that of mobile Personal Smart Spaces capable of personalising the configuration of fixed smart spaces, such as cars for instance. Seats, steering-wheels, air-conditioning systems can thereby be adjusted according to personal preferences. • PSS also generate new business models. This means that one user can become a micro-operator for internet service provision for another one that temporarily lack in connectivity. Hence, one Personal Smart Space can act as a broker between another PSS and its internet service provider.  Particular objectives of PERSIST:• Optimising space by creating open and extensible architecture in order to enable SMEs to use and augment smart spaces is a primary goal of the project. The promotion and adoption of standards around the PERSIST software stack will both impact dynamic service creation and advance service offers through open and agreed interfaces. However, in order to allow such standards to emerge, collaborative research must be advocated, one of the main priorities of the FP7 programme. • The project will also enable the creation of new networked services profitable for software providers, service/content providers, manufactures and operators. Overall, the development of such smart innovations will create new business opportunities in pervasive computing but also considerably enrich internal core skills in the area of smart spaces.
