In order to study long-term rest-activity patterns of elderly residents in care facilities, an infrared sensor system was developed. This sensor system detects a resident's presence or absence from their bed and their activity with little inconvenience. Using this system, the rest-activity patterns of two elderly people with dementia was assessed over a period of 3 months. For both subjects, frequent activity peaks and absences from their beds were often observed during the night. Such a sensor system will be useful for evaluating the sleep-wake rhythms of people with sleep disorders.
