In today’s extremely rich material civilization, it is necessary to take the initiative to combine the inheritance of the erhu art with modern means, and in this regard, an immersive virtual erhu playing experience multi-channel interactive system is proposed. The multi-channel interactive system for an immersive virtual erhu playing experience is constructed by combining knowledge of erhu playing. The multi-channel interaction function module of this system consists of acoustic feedback, haptic perception, gesture recognition, and line-of-sight tracking interaction, while the virtual playing module contains two parts: dynamic guidance teaching and navigation menu distribution. Based on the research purpose, the system function and teaching effect are verified and analyzed. The results indicate that the system can recognize simple erhu-playing gestures with a recognition rate of 100.00% and can recognize relatively complex gestures with a recognition rate of more than 95.00%, thereby providing users with an enjoyable erhu-playing experience. The three aspects of erhu playing knowledge, rhythm ability, and improvisation ability show a significant difference between the traditional erhu teaching method and the system presented in this paper, with a P-value of less than 0.05. This difference clearly demonstrates the promotion effect of the interactive system on erhu performance teaching.
