User-oriented services based on sensor data

This paper explores the issue of creating end-to-end services for older adults and their caregivers starting from a continuous gathering of sensor data from their living environment. The described work is part of the GiraffPlus project in which an intelligent AAL environment has been developed. The whole system relies on a state-of-the-art middleware for sensor data gathering and the pursued perspective is the one of designing added value services based on such data. The paper presents the general project concept and its different ingredients then presents two different services: a reasoner for person tracking, and an interaction service that connects the human network involved in a given application environment.
