[Purpose/Significance]Applying virtual digital humans for teaching in educational environments can lead to more efficient online learning for users.This study aims to investigate the impact of virtual digital human characteristics on the effectiveness of users'online learning,providing insights for the design of online instructional videos and the optimi-zation of teaching strategies to enhance learner efficiency.[Method/Process]Based on the theory of parasocial interaction,the study designed instructional video materials featuring virtual digital humans with VTube Studio software,which explored the situation of virtual teachers teaching in online learning environments.Users were recruited to watch the instructional vid-eo,and their subjective perceptions were measured.[Result/Conclusion]The features of attractiveness and anthropomor-phism of virtual digital humans have a positive impact on online learning performance through a chain-mediated effect of users'attitudes and learning satisfaction with the virtual humans.Additionally,a masking effect exists between the anthro-pomorphism and learning performance mediation pathway.Parasocial interaction has a positive impact on learning satisfac-tion,but affects learning performance negatively.
