Outline of Final Research Achievements	This research has been conducted with the aim of elucidating and realizing mechanisms for dialogue engagement, especially by the elderly and mental disabled. The Kyoto University group (Kawahara et al.) has developed a robot that conducts attentive listening with various methods of generating empathic responses. The Osaka University group (Yoshikawa et al.) has developed a robot that develops dialogue by collaborating with multiple robots and by referring to people with whom it interacted before. Both groups, in collaboration with Prof. Kumazaki in group A01, conducted dialogue experiments using robots with psychiatric (mainly schizophrenic) day care users over a period of two years.
Free Research Field	知能情報学
Academic Significance and Societal Importance of the Research Achievements	高齢者や精神障害者とも長い時間対話を継続するための方法論を確立できた。言語情報だけでなく、適切なターンテイキング、相槌生成、視線配布などの有効性を示した。さらに、共有笑いを生成するロボットは世界的なメディアで取り上げられた。２年以上にわたり、精神科（主に統合失調症）のデイケア利用者を対象に対話実験を行い、システムの様々な改善や利用法に関する知見が蓄積されるとともに、このようなシステムが受け入れられるようになった。
