# Designing an Educational Metaverse: A Case Study of NTUniverse
## 1 Introduction
Despite this, research supports the idea of immersive training's effectiveness and its ability to generalize skills from virtual to real settings, confirming its value and applicability across diverse professional domains [6]. Previously implemented designs of digital twins and applications of the metaverse in the healthcare industry and medical training are well reported; these aim to transform healthcare domains [7], including breast cancer monitoring and the training of new doctors [8]. Designs based on the Unity 3D development engine, which are used in a variety of industry verticals including automotive, manufacturing, energy, and aerospace [9], are discussed in terms of different applications, such as smart cities [10], robotics control [11], and guided tour [12]. Online and remote education and training have maintained their popularity in colleges and industrial organizations since the COVID-19 pandemic. Embodying education within the metaverse to provide an immersive learning and skill-development environment offers many advantages, such as effective collaboration with other learners and augmented training experiences. The use of virtual digitalization and simulations in a shared 3D virtual space in real time for educational and tutoring purposes can improve workflow efficiency and reduce testing costs. Conventional approaches that bear little physical resemblance to the hazardous environment are frequently employed, with the result that the sensory data obtained is insufficient to generate the impression that one is truly there. Because metaverse and digital-twin technologies can recreate complex representations of the work environment which would be challenging, costly, or dangerous to replicate in the real world, they can achieve strong physical fidelity and effectively place trainee workers in a highly realistic scenario. Knowledge transmission can therefore be enhanced via training simulations that make use of these technologies. Therefore, building a digital campus or industrial site can potentially maximize the effectiveness of knowledge acquisition and production capabilities, generating better learning outcomes, while limiting the downside in terms of the equipment costs for initial installation, and maintenance needs. The objective of this research is to explore the implementation of a practical use case in education and training for the metaverse and digital twin technology; this implementation is powered by the Omniverse platform developed by NVIDIA, which is utilized by enterprises like Amazon Robotics, whose intricate operations necessitate over 500,000 mobile drive robots to support warehouse logistics, and PepsiCo, whose digital twin improves supply-chain efficiency and environmental sustainability [13]. NTUniverse is a campus digital twin of Nanyang Technological University (NTU) in Singapore, which is constructed mostly according to the real-world campus settings. A future train transportation system on campus has also been designed virtually [14]. As the base of the educational metaverse, NTUniverse provides immersive and interactive learning activities in NTU. The remaining part of this paper is organized as follows. The overall process of the system design and methodology of NTUniverse is presented in Section 2. Section 3 focuses on the digitalization of the NTU campus. Section 4 discusses the design of the future campus-train system. The application of NTUniverse for virtual education is shared in Section 5. Section 6 concludes this paper.
