We present PhoMi, an interactive recall assistant that supports dementia reminiscence by engaging users with personal photographs captured via a live camera interface. Given a photograph, PhoMi delivers spoken questions and receives spoken responses, creating an accessible reminiscence setting with reduced reliance of human therapists. Over repeated sessions, user responses are incorporated into lightweight adapters of a vision–language model, enabling progressively personalized question generation without reprocessing prior interaction logs. PhoMi serves as a prototype toward scalable, lifelong AI companions for dementia reminiscence.
