In multi-user interaction, Embodied
Conversational Agents (ECAs) have to detect mental states of each user to interact smoothly and naturally. In addition, mental states of a person may be affected by extrinsic factors, such as states of people around. Physiological indices was useful to understand mental states of a person. However, it was impractical that ECAs measure physiological indices of users. The purpose of this study was whether we could detect intrinsic "involvement, enjoyment, and/or excitement" ("IEE") of a person and extrinsic "IEE" of an atmosphere, by using visual information. In other words, the purpose is to develop a method to detect an atmosphere of "IEE" in multi-user interaction.
