Shanghai yuancosmos investment promotion plan was released recently. By 2025, the industrial scale of yuancosmos is expected to exceed 350billion yuan. As a city that put forward the innovative idea of Yuan universe development earlier in China, at the end of 2021, the 14th five year plan for the development of Shanghai's Electronic Information Industry issued by Shanghai Municipal Commission of economy and information technology for the first time included yuan universe in the 14th five year plan for local industries. Discussing the topic of meta universe today is a bit like discussing "what the Internet means" in the 1970s. How to develop the yuan universe in Shanghai? What technologies are in urgent need of breakthrough? Which circuits are likely to be popular? The reporter interviewed Zhaoxing, Professor of Fudan University's big data research institute and deputy director of Fudan University's national intelligent evaluation and governance experimental base. At present, he is leading the construction of a "meta universe and virtual reality interaction joint innovation center" jointly built by more than ten global meta universe leading enterprises, ten domestic top universities and institutions. Virtual reality interaction, Shanghai Yuan universe development does not follow the "roble idea" Roblox, an American company, is currently the world's largest multiplayer online game creation platform. For the first time, the company has written metauniverse into its prospectus and proposed eight elements of metauniverse - identity, friends, immersion, low latency, diversification, anywhere, economic system and civilization. In the description of this game based company, Metauniverse is a virtual world that can be immersed and experienced as shown in the movie "number one player". Is the metauniverse a virtual world? According to Zhao Xing, at present, there are three paths in the meta universe going hand in hand. It is too early to define them. The three paths are: Based on the digital twin, the twin world pushed by the industrial Internet industry; A virtual world promoted by American enterprises based on games and social networking; Based on the traditional industry and Commerce of the real economy, some regions of China have explored the virtual and real interactive world. Zhao Xing said that in the "14th five year plan" for the development of Shanghai's electronic information industry, the "14th five year plan" emphasized three major contents, including the research and development of the underlying core technology of the meta universe, the development of new terminals for perceptual interaction, and the construction of systematic virtual content, which means that Shanghai's meta universe strategy is not a "Robles like" virtual game world, but more a realization path of "virtual and real interaction". What is the meta universe of "virtual reality interaction"? For example, if you suddenly become interested in the topic of how dinosaurs died out in class, you can find the corresponding topic from the terminal and enjoy a grand visual feast. Wait, when you hear this description, do you feel "right here"? Indeed, it seems that it has already existed around us. But different from the previous Internet, the meta universe allows you to create a virtual personality and bring virtual equipment of different platforms to various places, just like you wear clothes bought in a real shopping mall and go anywhere you want to go. Nine underlying technologies, vision and art are also the cornerstone of the meta universe The emergence of the Internet is inseparable from the use of a series of information technologies, such as the ability to make computers talk to each other from a long distance, the ability to jump from one web page to another with hyperlinks, etc. in addition, hardware devices such as monitors, keyboards and mice are also essential. The mobile Internet makes mobile phones the "third hand" of mankind. The same is true of the metauniverse. Zhao Xing's team studied the technical requirements for realizing the meta universe and summarized them into nine categories, namely, virtual reality (VR), augmented reality (AR), hybrid reality (MR), remote imaging (including air screen), artificial intelligence, 3D imaging, blockchain, Internet cutting-edge technology and art. It is not difficult to see that visual technology is one of the well deserved cores leading to the meta universe. As long as the display delay of VR eye mask exceeds 0.02 seconds, a small number of people will feel like vomiting. Therefore, the high-resolution and low delay display technology is the key to make most people accept the meta universe, which involves all aspects of the information industry, such as hardware, algorithm, network speed, etc. For example, 5g is indispensable to achieve high-speed information transmission with low delay. Imagine if people in sci-fi movies often point out the screen from the air and operate it. This is remote imaging, which is also one of the main technologies of the metauniverse. It can image through the gas in the air and conduct human-computer interaction. It is somewhat surprising that art is also regarded as one of the important technologies of the meta universe. In fact, it is not difficult to understand. Considering the current Internet products, whether consumers have higher and higher requirements for industrial design, UI, vertical painting and other visual images. Zhao Xing said: "when the technology is indistinguishable from each other, whoever can produce an interface that is more in line with the public's aesthetics is likely to win in the fierce competition." Advance layout and build strategic advantages for future development Shanghai has fertile soil for the survival and development of the meta universe. Both the demand for the development of digital technology and the pursuit of new growth points by Internet enterprises are promoting the arrival of the meta universe era. In Zhao Xing's view, if you want to play with the meta universe, you can't do without smart terminals like mobile phones. People are still guessing what the "entrance" of the meta universe is. Glasses are the most popular option at present. In this regard, Shanghai has one of the best enterprises in the industry. Once successful, it is the same as the "apple" company in the yuan universe. At the same time, Shanghai also has certain strength in chips, semiconductors and artificial intelligence. In addition to the underlying technology, metauniverse is still an industry driven track. In terms of the consumption capacity and potential of the meta universe, Shanghai has great strength in urban environment, industrial foundation, consumption foundation and industrial governance. Shanghai and the Yangtze River Delta have unique advantages that can be developed from a global perspective. It is not difficult to see from the statement of the meta universe industrial development plan mentioned by relevant departments for many times that Shanghai is taking a different road from the Western meta universe development. "Many people say that the meta universe is the next generation Internet. I don't agree with this view. I think the more appropriate expression is that the Internet is the meta universe of the previous generation." Zhaoxing said. (Xinhua News Agency)
