The health integrated smart home information system (HIS/sup 2/): rules based system for the localization of a human

The HIS/sup 2/ is a "health integrated smart home information system" devoted to the remote follow up of the patient living at home. This paper presents a decision algorithm, encapsulated in this telemedicine system, in charge with the localization of the patient in the smart home from the triggering of the human detectors. Up to day, the localization is achieved by the door contacts and the volumetric sensors installed in each room of the HIS/sup 2/. The relationship is not trivial, consequently a set of rules, experienced during the installation of the HIS/sup 2/, has been elaborated. Thus, a set of rules has been written, with the limitation to only one person living in the home. Furthermore, we define the term "volume", more convenient than the term "room", as a room can include several volumes. Then we classify into three kinds of volumes: the "destination" volume, the "communication" volume and the "exchange" volume. This enables us to select the right sensor to be implemented with its best position inside the HIS/sup 2/.
