A Prototype of Context Awareness Architecture for Ambience Intelligence at Home

Ambient intelligence is an interdisciplinary field that brings together ubiquitous computing, intelligent environments and context-awareness technologies. This paper describes a context-aware prototype for home environments, and the underlying concepts that we have developed. We propose a standardised representation of the environment context, in such a way that the integration of new developments (i.e. smart agents) is made simpler. A middleware that supports this standardised representation has been developed. This paper makes an especial emphasis on a proposed ontology that deals with information flows in the smart room. As an example, a ubiquitous broadcasting digital audio application has been implemented and tested in a real environment. Identification-based services by RFID sensor fusion are presented as a complement to the smart room.
