ユビキタスセンサによる独居高齢者見守りシステム(機械力学,計測,自動制御)  [in Japanese] Senior Citizen Monitoring System by Using Ubiquitous Sensors(Mechanical Systems)  [in Japanese]

Recently, the number of senior citizens who live alone is increasing tremendously in Japan. The senior citizens who live alone have less support compared with the one who lives as a couple or with family. In this paper, we propose senior citizen monitoring system that detects emergency status by using ubiquitous sensors. The proposed system is composed of behavior recognition sub-system, life pattern generation sub-system, and emergency detection sub-system. The behavior recognition sub-system recognizes the human behaviors by using rule-based system. The life pattern generation sub-system extracts typical life patterns of a user. The emergency detection sub-system finds the emergency statuses by using fuzzy inference system. We developed the proposed system by using ubiquitous sensors and confirmed its efficiency by experiments.
