Paper Abstract:
|
The numbers of the elderly people who live alone have been increasing in Japanese society. One of the countermeasures against solitary elderly peoples problems is the development of a safety confirming system. Past studies indicated that measurement of acceleration on fixtures at home may be able to become a method to confirm the solitary elderly persons condition at their home. However the acceleration measurement at multiple positions in the house may be applied not only as a safety confirming method, but also as a health confirming method. In brief, the rhythm observed in the acceleration variation may indicate the inhabitants usual behavior rhythm. The results of a month-long record of six fixtures indicated that subjects have their own behavior rhythm on each day. When some irregular wave was recorded out of their rhythm, we can suppose that some irregular event has occurred. For example, the variation of bedroom door acceleration indicates the subjects behavior through the night. When no acceleration was observed at the time to go to bed, the subject did not use the bedroom, but had dozed off in the living room in spite of risk of cold. Also there were other flat lines through the measurement period. Those flat lines meant the subjects absence of movement. These facts mean that we can confirm elderly peoples behavior, health condition and safety by measurement of acceleration of fixtures. |
