Steps toward end-to-end personalized AAL services

Quite an amount of effort has been given in Ambient Assisted Living ap- plications to the issue of gathering continuous information at home, standardizing formats in order to create environments more easily, extracting further information from raw data using different techniques to reconstruct a context. One aspect that is rather important but less developed in current investigation is the design of person- alized end-to-end services for classes of users of such technology being them either primary user (older people) or secondary users (medical doctors, caregiver, rela- tives). This paper describes the current effort in the EU GIRAFFPLUS project for designing and implementing such services on top of a state-of-the-art continuous data gathering infrastructure. In particular after presenting the general integrated idea pursued in the project we will describe a service for personalized interaction and visualization and its specialization for primary and secondary users.
