From sensor data to user services in GiraffPlus

This paper presents an ongoing effort to create added value complete services for end users on top of an AAL continuous data gathering environment. It first presents the general architecture proposed by the GiraffPlus project for long term monitoring of older users at home, then describes the main choices concerning the middleware (universAAL compliant), the long-term data storage, and a user- oriented component, called DVPIS, dedicated to interaction with different users of the AAL environment. The current status of a deployed version of the system is then shortly described.
