Abstract

In this article, we discuss the evaluation of an impression displayed by presentation contents which are constructed by a dialogue between embodied characters. There are many types of presentation style to provide information to users 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 of the embodied characters. People 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 apply this knowledge to a dialogue between embodied characters, which provide information to users, so that we evaluate if the presentation dialogue expresses the corresponding atmosphere to an expected atmosphere.
