Recently, the demand of nursing care rapidly has been increasing along with the progress of serious aging society in Japan (1) . Accordingly, the physical burden to the caregivers is increasing. In care works, it is important to watch over care-receivers with privacy preservation in the house or the nursing home. Thus, it is difficult to use the systems with security or surveillance cameras that might violate the care-receivers' privacy. In order to solve the problems, the Obrid-Sensor that can detect the position and condition of the subject without privacy violation has been developed in previous researches. However, the Obrid-Sensor did not correspond the detection of multiple subjects. Moreover, in order to obtain the subject's position information from a higher perspective, a complex installation of the Obrid-Sensor has to be introduced. Therefore, we propose the tracking method by estimating the horizontal and depth position of the subject simultaneously with one Obrid-Sensor in this research. The installation of the Obrid-Sensor in the proposed method is simple. It is also possible to track multiple subjects respectively at the same time.

“…The others installed sensor, such as mat sensors, are difficult to introduce because the sensor is needed to install all over the floor. Thus in our previous study, we developed a system using a Obrid-Sensor to watch over the elderly people based on the acquired brightness distribution (8) . the sensor can acquire brightness information like a camera, but it can protect privacy due to compression to one dimension.…”

The aging problem in Japan goes more and more serious. For lightening the burden of care workers in Japan, systems to confirm safety of elders in daily life attract a lot of attentions in recent years. In this research, a safety confirmation system for elders living in outlying island is designed. As a part in the system, a motion detection system using ultrasonic sensor is reported for safety confirmation of elders living in outlying island in Japan in this paper. Ultrasonic sensors are employed as observers for object detection and distance measurement in restroom for safety confirmation. According to privacy protection requirement in nursing, the ultrasonic sensors apply no image or video information are good for applications in daily care of elders. By employing the proposed method, motion of target person can be detected. The effectiveness of the proposed method is confirmed by experiments.
