Abstract (in Japanese) (See Japanese page) 
(in English) With the recent progress of human sensing and AI technologies, many studies on recognition and estimation of human internal states, such as emotion recognition from facial expression or emotion estimation from physiological indices such as heart rate, have been conducted. We have proposed original methods on emotion estimation using body movement based on Lavan Movement Analysis, and that using eye region information, and demonstrated the effectiveness of them. In this study, we analyzed relationships among body movement, eye region information, and physiological indices such as RRI, LF/HF and pupil diameter in emotional expression. First, we performed an experiment to measure various data in video watching task to evoke emotions in natural setting. Then, using the data, we calculated feature values and performed emotion estimation using machine learning and analyzed feature importances. As a result, we made clear the importance of Space and Weight of Lavan Movement Analysis, and the distance between eyebrows.
