The Shanghai Science and Technology Commission issued the "Shanghai "Metaverse" Key Technology Action Plan (2023-2025)". The main direction of the program includes immersive technology and Web3 technology. In addition, to meet the needs of the production of massive immersive audio-visual content in the "Metaverse", based on the technical route of AI empowering virtual and real integration, it focuses on the layout of artificial intelligence-generated content (AIGC), cross-scale collection Reconstruction, digital human generation and driving, virtual space three-dimensional engine and other key technology research and development, realize the automation and low-cost production of hyper-realistic "Metaverse" immersive audio-visual content, and support the ecological construction of "Metaverse" content creation. The plan points out that centering on the technical requirements for the immersive experience of virtual-real fusion in the "Metaverse", the immersive computing technology route based on device-cloud collaboration will focus on the development of key technologies such as spatial computing, intelligent coding, and distributed rendering distribution to enhance the content of the "Metaverse". Computing and distribution efficiency; facing the development trend and demand of high-definition and deep immersion in the content presentation of "Metaverse", focusing on the layout of high-performance and low-power micro-display devices, high-brightness and lightweight optical modules, holographic and light field displays and other key Technological breakthroughs to seize the key entrance highlands of the "Metaverse", and promote the high-quality development of new display industries such as near-eye display and naked-eye holography. Facing the decentralized/multi-centralized organization rules of the "Metaverse", based on the heterogeneous multi-chain fusion technology route, the focus is on the support of Web3 network operating system, blockchain digital identity, distributed trusted storage, and trusted computing chips Technology and digital regulatory technology research and development, building a high-performance, scalable, secure and controllable new blockchain architecture, and forming an infrastructure to carry large-scale "Metaverse" innovative applications.
