XR refers to technologies like VR, AR, and MR that encompass next-generation computing platforms and help bridge digital and physical worlds, resulting in enhanced computing performance and connectivity across the board. XR has revolutionized content display and human-machine interactions, and represents a flourishing market worth tens of billions of dollars.

Virtual reality (VR) has been widely adopted in the field of education. Students can leverage VR to experience the geographical features of far-off lands firsthand, and enjoy enriching, immersive learning experiences. Augmented reality (AR) has made great strides in a number of entertainment and B2B domains, including security, industry, tourism, and healthcare. AR smart glasses also boost work efficiency by streamlining operations and enabling remote assistance. Mixed reality (MR) is the combination of VR and AR. It introduces real scenario information into the virtual scenario, and establishes an information loop of interactions and feedback between the virtual and real worlds to create a heightened sense of reality. The emergence of MR has helped break through the inherent limitations of VR resulting from its entirely virtual nature, enabling an expanded range of human-machine interactions with equally broad commercial applications. However, current XR devices still face the following challenges:
