We are concentrating on the rhythms of a daily life that become basic for safety and health in elderly people’s daily life, and have developed the measurement evaluation technology. In this report, we introduce the technology that measures body movement in the bed by using an infrared sensor system to evaluate the quality of sleep. In addition, we classified daily life behavior from the viewpoint of QOL (quality of life) into about 15 kinds of body activities, and provided standard behavior to each body activity. We introduce the technology that measures the body activity in daily life by using acceleration sensors.
