Time-Course Action Analysis of Daily Life Investigations in the Welfare Techno House in Mizusawa

Abstract

In this study, we have examined the possibility of non-intrusive monitoring at home. We describe the experimental results of the relation between an individual's recorded behavior and the actions detected by the sensors during the course of the subject's daily life. Infrared sensors and the opening of doors and windows and the use of appliances were used. In this paper, it is assumed that the subjects were sleeping when there were no responses by the infrared sensors or when only the bedroom sensor was responding. The sensors were able to detect excretion by using the outputs of the infrared sensor and the water valve of the lavatory, even if a subject did not record it in the time-course of daily life during the investigation. Our findings show that the actions of subjects who stayed at Welfare Techno House (WTH) in Mizusawa could be estimated from outside the house, especially for sleeping and excretion.
