The flow of the experiment was following; we first displayed one of emotion-eliciting films, and participant expressed (fake) smile just after watching the film. At the end of the experiment, we let them assess what emotion they felt with two self-report measures. We prepared six emotion-eliciting films in order to record various face expression with various emotion. Then, we obtained face landmark positions from the face on the recorded video using a method proposed by Kazemi et al(1). We focused that eyes and mouth corners move well while smiling, and defined 15 feature values related to that landmarks. Furthermore, we grouped the feature values in emotion scores by clustering. There are significant differences in eye area between happiness and disgust, and in some mouth corners’ feature values between happiness and fear as a result of comparison of clusters. we considered these differences resulted from disgust/fear, but negative emotion.</p>
