Metaverse has vast potential for application in diverse domains, including education, entertainment, commerce, and social interaction.In education, Metaverse can provide students with an immersive learning environment that enhances their learning experiences [5].In entertainment, Metaverse offers opportunities for novel and more enriched gaming and entertainment experiences.In commerce, Metaverse generates new business models and marketing channels for enterprises.In social interaction, Metaverse provides users with entirely new means of socializing and facilitates interpersonal communication and information dissemination [6].

User-centered design
User-centeredness is critical in the design process of the Eurasia University Library digital twin model.To provide personalized and efficient services that meet user expectations, a comprehensive understanding of user needs and habits is necessary.Throughout the design process, a focus on user experience is vital in order to improve operational flow and reduce the difficulty of usage.

Enhanced interactivity and immersion
Enhanced interactivity and immersion are core advantages of Metaverse.In the design process, it is crucial to fully utilize the unique features of Metaverse to enhance user interaction and immersion within the virtual library.This includes the use of high-quality 3D models, dynamic scene design, and enriched interactive elements.

Construction of virtual library scene
To realize the Eurasia University Library digital twin model, the first step is to construct a virtual library scene.The construction of this scene should reference the actual layout and design of the library to create a highly realistic virtual environment.Various functional areas should be included in the scene, such as reading rooms, library resource retrieval areas, and online academic activity areas.Attention should be paid to detail in the scene design to facilitate smooth navigation and use of all functions within the virtual library for users.

Interactive interface design
The interactive interface design is a core component of the virtual library that determines how users interact with the virtual library.The interface design should be simple and easy to use, with consideration given to user operational habits.When designing the interface, different devices and platforms must be taken into account to ensure cross-platform compatibility.In addition, the interface design should include real-time feedback and prompts, allowing users to understand their operating status and results.By optimizing the interactive interface design, user operational efficiency and satisfaction can be improved within the virtual library.

Construction of digital twin 3D model
Utilizing processed data, three-dimensional modeling software such as 3ds Max, Blender etc. can be used to create the digital twin model of the Eurasia University Library.The model should accurately reflect the actual structure and layout of the library while exhibiting high levels of simulation.In the process of model creation, factors such as lighting, texture, and animation must be considered to enhance the realism and immersion of the model.

Selecting an appropriate virtual metaverse platform
To implement the application of the digital twin model within a virtual metaverse, it is essential to select an appropriate virtual metaverse platform.The selection of such a platform should consider factors such as platform maturity, scalability, compatibility, and community support.For instance, virtual metaverse platforms such as Unity and Unreal Engine are prevalent in the current digital landscape.

API interface development and integration
Once a suitable virtual metaverse platform has been selected, the development of API interfaces is required to achieve integration between the digital twin model and the platform.The API interfaces should include functionalities such as data synchronization, user interaction, and resource retrieval.Through the API interfaces, the digital twin model can be embedded within the virtual metaverse platform, enabling users to access books, participate in activities, and communicate with others within the virtual library.Furthermore, the API interfaces must support real-time updates to ensure that any changes occurring within the actual library are reflected immediately within the virtual library.
