Dementia symptoms arise from acquired brain dysfunction, making them highly individual and diverse, requiring flexible responses in care settings. In this study, we investigated the use of VR-based patient experience (PX) spaces and AI avatars as interventions toward establishing a multi-perspective learning method for dementia care education. First, as a first-person perspective experience, we conducted a co-creation experiment involving real-time prototyping with individuals with dementia, constructing VR content that reflects their subjective experiences. Second, as a second-person perspective experience, we introduced an AI avatar that mimics individuals with dementia and conducted a preliminary experiment examining differences in critical thinking with and without guidance. These investigations suggest the importance of co-design with people with dementia and the potential of AI avatars to support learner reflection.
