This paper reports the result of analyzing sensor logs that are obtained from sensors installed in an actual nursing-care home and those attached to care staffs. Japan is now facing a super-aging society, and the number of elderly people needing care is increasing. ICT (information and communication technologies) is expected to play a key role to provide various care services while keeping privacy and QOL of elderly people. This paper aims to identify care staff’s activities as well as analyzes residents’ sleeping condition by using such sensors as commercially available with relatively low cost, such as a beacon, an acceleration sensor, and a sleep meter. The results of analyzing sensor logs obtained from an actual nursing-care home show that such activities as recreation and cleaning can be identified with relatively high accuracy. The analysis result also reveals typical sleep state of residents, and relationship between activities in daytime and sleep length.
