The Shanghai Science and Technology Commission recently issued the "Shanghai MetaUniverse" key Technology Action Plan (2023-2025), which puts forward that we should take immersive technology and Web3 technology as the two main directions, and take independent innovation and open cooperation as the promotion path. Strive to improve the self-reliance and self-reliance of science and technology in the field of "meta-universe". Important progress should be made in tackling key problems of originality and leading science and technology. New breakthroughs have been made in strategic frontiers and key technologies, such as artificial intelligence generated content (AIGC), spatial computing, intelligent coding, high-performance and low-power micro-display, multi-mode sensing, Web3 network operating system, cross-scale acquisition and reconstruction, brain-computer interface, etc., focusing on intelligent terminals, content production, cloud platforms, etc., to form more than 30 influential core technologies and products. We will promote the "meta-universe" innovation chain, industrial chain and value chain to the high end.
