This study analyzes the impact of haptic interaction on the dissemination of cultural information and investigates the feasibility of virtual reality technology for cultural dissemination. Additionally, based on SMPL interaction technology, a dynamic character model was designed for virtual scenes. Additionally, a virtual reality-based interactive cultural heritage platform for the Hulusi instrument was developed, with interactive functions designed across four key areas: virtual exploration, model interaction, message interaction, and panoramic image interaction. The platform was applied to the dissemination of traditional Chinese music and cultural arts, with an analysis of the impact of virtual reality technology on its dissemination. Respondents rated the openness, timeliness, social nature, and anonymity of virtual reality technology above 4 points, indicating its high feasibility in cultural dissemination. When the key point accuracy threshold was set to 0.2, the average accuracy rate of user labeling for dynamic characters generated by the SMPL method reached 95.36%, indicating good character generation effects at this threshold. The platform’s interactive modules significantly influence users’ emotional experiences, and users expressed high satisfaction with the platform’s effectiveness in promoting traditional music and art culture. Only 5.91% to 18.90% of respondents indicated dissatisfaction or strong dissatisfaction with the survey dimensions. Users reported the highest satisfaction with the platform’s interactivity, and most users expressed willingness to recommend the platform to friends for use.
