Abstract
Recently, the caregiver's burden is increasing in the aging population. It is said that 70% of the events that nursing care becomes necessary for elderly people are caused by cerebral vascular disease, dementia, disease of the joints and so on. These diseases can be prevented by the improvements of their life. However, it is difficult for the elderly people and caregivers to notice the warning from the small change of daily life. Therefore, a life-logging system can be one of the solutions for this problem. In our research, we developed a life-log management system for the elderly people and caregivers in informationally structured space.
