Proposing a Personalized Quiz Service for Assisting Self-Evaluation of Elderly Cognitive Memory

Currently in Japan, the number of elderly people with dementia is increasing. Dementia is difficult to treat fundamentally, and treatment is mainly aimed at slowing down the progression, making early detection important. However, dementia progresses slowly without the person's awareness, making it very difficult for the person to notice. Also, many elderly people feel burdened by going to the hospital for examination. Our research group focuses on supporting the elderly with technology. In previous study, we have developed a service that analyzes the user's mind by conversing with the user on a daily basis using an agent that communicates via text using the LINE application. We thought that we could use this agent to help detect dementia early in daily conversations. In this study, we propose and implement the “Memory Keeper Quiz Service”, a service that conducts quizzes on users through daily conversations with agents using the LINE application to help the elderly notice the decline in cognitive memory.
