Abstract
One or more sensors for detecting daily activity patterns are provided in a person's home. A data processing apparatus includes databases for storing activity data from the sensors, a statistical analysis section, an abnormality determination section, an evaluation section and a notification section. The statistical analysis section performs statistical analyses on the stored activity data and calculates thresholds for detecting abnormalities in daily activity patterns. The abnormality determination section compares the living behavioral values with the thresholds calculated by the abnormality determination section and determines abnormalities. The notification section notifies an observer's reporting apparatus of the abnormalities. The observer checks whether the person observed is actually abnormal or not, by communicating with the person; and the observer gives feedback about accuracy of the abnormality notification, enabling the apparatus to learn which daily activity patterns are optimal for the abnormality determination.
