Abstract
We have developed a system for telemonitoring a television's operating state (TVOS). The TVOS pattern has been shown to reflect the daily living condition of subjects. However, it is difficult to speculate upon the daily living conditions from TVOS if a subject doesn't watch much TV. In this study, we developed a novel telemonitoring system to monitor not only TVOS but also indoor illuminance. We also developed a data transfer protocol for the novel system using e-mail. The system allows users to form a network to evaluate living conditions of remotely located family members. A feasibility test was performed in nine subjects (four families). The results showed that (1) the illuminance information helped users to speculate upon the daily living conditions of their family members, (2) patterns of the TVOS and the illuminance were different in each subject, and (3) in the questionnaire about the novel system, the subjects who used the novel system more than a half year and were 40 years old and over were satisfied with its design and performance.
