“…However, from the viewpoint of privacy, it is difficult to introduce cameras in daily life. As the method not encroaching on their privacy, there are leaving the bed detection systems that detect by using clip sensor (4) , mat sensor (5) and ultrasonic radar (6,7) . Nevertheless, because they are touched by users, there is a possibility that are broken, and the sensor is visible, so there is the problem the subject avoids it intentionally.…”

Recently, due to the aging of population (1) , the increasing of dementia patients has become social problem. The dementia patients are feared to go wander, and some of them may be gone missing after going out and have a risk to encounter accident (2) . However, watching over them all the time is difficult. Especially watching over at midnight or after sleeping is mental burden for helpers. In order to solve the problem, watching by camera is given, but it is difficult to use cameras in daily life from the viewpoint of privacy violation.As the solution for this problem, we have developed one-dimensional brightness distribution sensor (Obrid-Sensor) that can detect the subject's position, motion and condition without violating their privacy. In this paper, the method of leaving the bed detection that detect the leaving the bed motion day and night by installing the sensor in the edge of in the bed and irradiating infrared light is proposed.
