| contents | Since the COVID-19 pandemic, online lectures have spread rapidly and many students are satisfied with them. However, one challenge remains the loss of concentration due to the lack of students' copresence. Our previous work suggests that presenting 3D characters with appropriate actions has the potential to improve concentration in online lectures. Nevertheless, an effective combination of actions has not yet been identified. In this study, we developed a lecture watching system that presents a 3D virtual classroom using a naked-eye 3D display. The system includes student characters that show copresence with various actions such as nodding, notetaking, and sleeping. An evaluation experiment was conducted with two conditions; (1) student characters perform only positive actions and (2) both positive and negative actions. The results, analyzed using posture and notetaking behavior as key indicators, suggest that the system can help to maintain concentration when the student characters perform both positive and negative actions, rather than only positive ones. These findings provide promising strategies for maintaining student focus in on-demand lectures and contribute to the development of more effective online education systems. |
