Abstract
In this age of the corona disaster, face-to-face lectures have been decreasing and on-demand lectures have been increasing. However, the role of students beside oneself in real classroom interaction is important. In this study, we expand this to on-demand lectures. To understand the interaction of students in on-demand classes, we created lecture videos and a CG classroom based on a real classroom. In addition, we introduced a nodding mechanism for student characters. On the basis of this, we conducted classes using 2D video, 360-degree video, and VR using an HMD, and we clarified the differences between 360-degree video and VR. We also performed questions about movie types and character behaviors. The results of the evaluation of movie types indicate that using VR in on-demand classes can make students feel a relationship in the classroom. The results of the evaluation of character behaviors show that rash action is useful in some cases.
