In this article, we analyze the relationships between nonverbal expressions and atmospheres during face-to-face dialogue by persons aiming to apply to an information character. Information characters provide information to viewers through their dialogue to get a better understanding. If the way which information is shown through an embodied characters' dialogue is adopted, the characters have the faces and bodies in order to be "embodied", so, the information provider must care about meanings of a state of nonverbal expressions displayed by the embodied characters. People also display and exchange nonverbal expressions including eye-gazes, noddings, and facial expressions in daily conversation. Nonverbal expressions convey various kinds of information that is essential to make our face-to-face communication successful. In the previous work on social psychology, it is known that there are interdependences among nonverbal expressions between those from different persons in conversation with each other. We investigate dialogue scenes of TV shows to convey information, with a goal of applying above knowledges to a dialogue between embodied characters, which provide information to users.
