Impression Analysis of Animated Agents in Soft Game Theory

Abstract

In this paper, we investigated users' impressions of animated agents by conducting an experiment involving subjective evaluation. In order to devise strategies by using an agent's nonverbal information, it is important to investigate not only the effects of facial expressions but also the user's impression of the agent. To evaluate such impressions, we developed an experiment based on Soft Game Theory, which considers players' emotions. Based on factor analysis, we found ""friendly"" and ""truthful"" as the users' impressions of the agent. The findings were useful in devising the strategies.
