Dialogue Robot

This study presents a dialogue robot system that elicits place-related memories from users during walks. Reminiscence therapy is a psychotherapeutic approach that promotes mental well-being by encouraging individuals to recall and narrate past experiences, yet its conventional practice requires the involvement of trained professionals. The proposed system combines GPS-based location information with a large language model (LLM) to generate location-aware dialogue, exploring the potential of a robot that supports everyday reminiscence without professional involvement. When the user revisits a previously visited location, the system draws on the dialogue history to enable personalized interactions. As a pilot study, we implemented a prototype targeting university students and confirmed the functionality of point-of-interest arrival detection, dialogue generation, memory extraction, and visit-count-dependent response switching. In the dialogue logs, reminiscence-related utterances were observed in response to location-aware prompts.
