DANGEROUS SITUATION AWARENESS SUPPORT SYSTEM FOR ELDERLY PEOPLE WITH DEMENTIA

摘要

"Group Home" is a type of home-based care service for the elderly people in Japan who suffer from dementia. Sometimes, accidents occur in daily life at home. Elderly people with dementia pnd it is difpcult to notice certain dangers because of their aging process. In this study, we focus on risk aversion methods. The method alerts the elderly people to risks. We develop a system that enhances their risk perception. Therefore, they will be able to avoid certain dangerous situations. In this paper, we present the structure of the system and its prototype. The system performs three components; (1) it recognizes the behavior and situation of the elderly person, (2) it estimates the risk, and (3) it notipes the person about the risk when it is estimated to be high. A sensing device is used for the prst function. In this research, we use an ultrasonic position detector to recognize an elderly person's situation. The risk estimation is performed based on Semantic Web technologies such as OWL and RDF. Risk notification is realized using a moving projector and speaker.
