Aware and smart environments: The Casattenta project

"Casattenta" (Aware home, in Italian) is the demonstrator of a research project on "Ambient Intelligence", "Sensor Fusion" and "Wireless Sensor Networks". The result is a system composed of fixed and wearable sensor nodes, providing elderly people living alone in their house (but also people in other situations and environments) with adequate and non-intrusive monitoring aimed at improving their safety and quality of life. The system consists of fixed smart sensors distributed in the environment and wearable ones monitoring the inhabitants' health and activity. The interaction between fixed and mobile nodes, based on the ZigBee compliant technologies, allows indoor tracking and identification of dangerous events.
