Telemonitoring system of television´s operation state for elderly people living alone

We have developed a telemonitoring system of television´s operation state (TVOS) in caring for elderly people living alone. A feasibility study was achieved for over three months in a home of a subject of 80-years-old female living alone. It was shown that the consistency of the daily rhythms of the TVOS and TVOS of the different pattern on every day of the week. The accumulation time of TV use of a day correlated inversely with an activity evaluated from a pedometer attached to the volunteer. The TVOS would reflect a living condition of the elderly person living alone.
