## 6 Design Strategies and Case Studies
### Design Case  
With the aid of meta-universe technology, the \"Cross-Music\" project aims to preserve the traditional Chinese musical instrument culture that is in danger of disappearing while also assisting users in understanding the history and performance of lost musical instruments. As seen in Figure 7, the project \"Cross-Music\" is a real-world example of this paper's practical case study.  
* Technical Support: The system employs advanced virtual reality technology to create a hyper-realistic virtual environment. Through 3D modeling, dynamic lighting, and shadow effects, ancient musical instruments' visual and acoustic properties are meticulously recreated, providing users with a deeply immersive experience. The system also supports multiple interaction methods, including gesture recognition and voice commands, enabling users to interact with the virtual environment naturally and intuitively. For instance, users can simulate playing a Shakuhaichi flute through gesture recognition, allowing them to experience the nuances of playing the instrument. To ensure a seamless experience, the system has been optimized for fast response times and technical stability, minimizing delays and lags for smooth, uninterrupted interaction.
* Emotional Experience: The system creates a rich emotional experience through a well-crafted storyline centered around the transmission of musical instruments and an engaging role-playing mechanism. As users explore the virtual environment, they encounter various historical figures, engage in meaningful dialogues, and complete interactive tasks that deepen their connection with the lost instruments' historical context and cultural significance. These interactions foster emotional resonance, allowing

users to appreciate the charm of ancient music and cultivate a more profound interest in and affection for traditional culture. Additionally, the project offers a personalized experience path, dynamically adjusting the difficulty and content of tasks based on the user's progress and preferences, further enhancing the user's sense of participation and accomplishment.
* Cognitive Dimension: Users are directed to actively investigate and learn about forgotten musical instruments using a task-driven learning technique. To improve their comprehension of the instruments through practice, users must finish several musical instrument-related chores, such as repairing the instruments and learning how to play them. Simultaneously, the system incorporates real-time feedback and incentive features, such as point rankings and achievement badges, to promote ongoing engagement and advancement. Furthermore, the narrative includes the background, manufacturing method, and associated cultural information of musical instruments, enabling users to acquire and engage with them organically through interaction, thus enhancing and advancing their cognitive abilities.
* Social Factors: By making it simple for users to share their experiences and learning outcomes on social media, cultural heritage education has a more significant societal influence. Through establishing discussion forums and event planning, the project has created a user community that fosters user support and interaction as well as collaborative learning and development. Furthermore, a cross-cultural communication element has been formulated to encourage communication and comprehension amongst users from diverse cultural backgrounds and augment the global influence of cultural heritage education, thereby serving a constructive social function.
