Abstract (in Japanese) (See Japanese page) 
(in English) With the goal of building an intelligent conversational agent that can recognize user's engagement, this paper proposed a method of judging the user's conversational engagement based on head pose data. First, we analyzed how head pose information is correlated with user's conversational engagement, and found that amplitude of head movement and rotation has positive moderate correlation with the level of conversational engagement. Then, we established an engagement estimation model by applying a decision tree learning algorithm to 19 parameters. As a result, it was revealed that the proposed model based on the head pose information performs quite well.
