Ambient Sensor System for In-home Health Monitoring
Toshifumi Tsukiyama · 2014
Abstract—In this paper, we deal with a sensor-based monitoring system, which evaluates the health status of the elderly based on daily living activities and provides the forecast of an emer-gency situation to a local nursing center without explicit user interaction. Here, the main focus is on reasonably priced and noncontact sensors which assure direct recognition of quotidian activities. For meeting these criteria, water flow sensors that are attached to faucets in the kitchen, washroom, and to the toilet are a promising solution. An advantage of this solution is that the system can be readily installed in any type of housing. In addition, this system does not require personal data to be saved or transmitted outside. We will present initial results from some experiments. Keywords–Ambient monitering system; Health care; Water flow sensor; Active RFID tag; Vibration sensor; Recognition of quotidian activity.
