Summary:In order to lighten the heavy burden of care workers in the aging society in Japan, many contributions have been made in safety confirmation systems for elders in daily life in recent years. A safety confirmation system for elders is proposed in this paper. The Obrid-Sensor and the ultrasonic sensor are employed in the system. The ultrasonic sensor is based on the theory of reflection of ultrasonic wave. And the Obrid-Sensor is constructed with rod lens and line sensor. Theoretically, the detections of the proposed method employ no images or video information. The application of the sensors performances quite well according to the privacy protection requirement in nursing. In the system, the applications of the sensors make it possible that we can observe the basic motion of subject alarming when he/she falls down, with privacy preservation. The effectiveness of the proposed method is confirmed by experiments.
