[The study of house monitoring system in Welfare Techno-House Mizusawa].

In 1999, 8 elderly people aged over 70 stayed for 5 days in Mizusawa Welfare Techno-house and their health conditions and activities of daily life were monitored using 16 sensors attached around the house. To determine a few feasible, practical sensors and optimal sensor positions, accumulated data was analyzed. Because of bud get conditions only two sensors (infrared sensor and life line monitor sensor) were placed in one voluntary house and the data were transferred from the voluntary house to the techno-house through the ISDN and CATV lines. The data were analyzed every days. Only 2 sensors to detect were placed and attached this year, however one more sensor to detect physical conditions such as ECG records during sleeping time, will be used next year. On the other hand, an integrate system that can analyze many data transferred from various sensors simultaneously was developed. To introduce this system into privatehouse, many problems such as privacy protection, security, etc must be solved.
