At today's game technology theme forum of "technological productivity of games in the process of digital reality integration", the research group of Wang Yanyu from the Chinese Academy of game industry and the Institute of the history of natural sciences of the Chinese Academy of Sciences jointly released the report "game technology - new technology clusters in the process of digital reality integration". The report reviews the development of game technology and related cutting-edge technologies for nearly half a century, puts forward the definition and connotation of game technology for the first time, and attempts to quantify the contribution of game technology in promoting the scientific and technological progress in cutting-edge scientific and technological fields such as chip, 5g and XR (VR / AR) extended reality. According to the report, the outstanding interesting attribute of video games masks its scientific attribute, so the game technology has long been ignored by people. In 2020, the contribution rate of game technology to the technological progress of China's chip industry is about 14.9%; For 5g and XR, the technological contribution rate of game technology reached 46.3% and 71.6%. According to the report, the birth of game technology was a "by-product" of promoting and verifying innovative theories in the field of artificial intelligence in the 1950s, and electronic games were born almost at the same time as computer science. Wang Yanyu said that the earliest hardcore players of video games were actually scientists in the laboratory. In addition, games drive many technological advances. In the field of hardware, games have created demand for semiconductor fields such as CPU and GPU, and promoted the success of chip companies such as NVIDIA. In the field of software, game development has promoted the development of game engine and cloud rendering, and laid the foundation for virtual reality technology. In the field of mobile communication, the pursuit of high bandwidth and low latency in games has promoted the development of 5g technology. It home learned that Ao ran, executive vice president and Secretary General of China Association of audio visual and digital publishing, said in the release of the report that the game industry is an important part of the digital economy. Re examining game technology can not only further release the value of game technology, but also better guide the healthy and sustainable development of related industries, which has important research and practical significance.
