An intelligent support system for elderly care with RFID tags and a cleaning robot

With the rapid increase of aging population, the development and introduction of ICT systems to the care field are proceeding. However, such systems using cameras and/or sensor networks are not necessarily accepted due to privacy protection, cost and unstable accuracy. Based on such discussion, this paper proposes support system for elderly care which monitor behaviors by using RFID tag with sensing function. Those tags are put around elderly people and detect a change in pressure, and the system judges the behaviors of an elderly person from its change. In addition, the system uses a cleaning robot. When a man falls on the floor, the robot moves to the location and confirm the consciousness by beep. The latter part explains those pressure sensing method and indoor positioning method using RFID tags, and experiments show high accuracy on each method.
