元宇宙技术及应用研究进展

元宇宙(Metaverse)是一个虚拟时空的集合，由一系列的增强现实(Augmented Reality, AR)、虚拟现实(Virtual Reality, VR)和互联网(Internet)组成，是一个平行于现实世界运行的人造空间，也被认为是互联网的下一个阶段，是由AR、VR、3D等技术支持的虚拟现实的网络世界。自2021年以来，国内外掀起了研究元宇宙的热潮。本文介绍了元宇宙的起源和定义、发展元宇宙的意义、元宇宙的技术体系、发展面临的问题和风险等；重点分析了元宇宙的主流技术体系和典型应用场景，列举了相关研究成果和观点；最后给出了元宇宙未来的研究方向。

Research Progress on the Technology and Application of Metaverse

The metaverse is a collection of virtual time and space,composed of a series of Augmented Reality (AR),Virtual Reality (VR) and the Internet,which is an artificial space running parallel to the real world.It is also considered as the next stage of the Internet,the virtual reality network world supported by AR,VR,3D and other technologies.Since 2021,there has been an upsurge in the study of the metaverse at home and abroad.This paper introduces the origin and definition of the metaverse,the significance of developing the metaverse,the technical system of the metaverse,the problems and risks faced by the development,etc.The mainstream technology system and typical application scenarios of the metaverse are emphatically analyzed,and the relevant research results and viewpoints are listed.Finally,the future research direction of the metaverse is given.
