Industrial Metaverse: Connotation, Features, Technologies, Applications and Challenges.

Metaverse expands the cyberspace with more emphasis on human-in-loop interaction, value definition of digital assets and real-virtual reflection, which facilitates the organic fusion of man, machine and material in both physical industry and digital factory. The concept of Industrial Metaverse is proposed as a new man-in-loop digital twin system of the real industrial economy which is capable of man-machine natural interaction, industrial process simulation and industrial value transaction. With the comparison with Metaverse and Digital Twin, the key features of Industrial Metaverse are summarized, which are man-in-loop, real-virtual interaction, process asserts and social network. Key technologies of Industrial Metaverse are surveyed including natural interaction, industrial process simulation, industrial value transaction and large-scale information processing and transmission technologies, etc. Potential application modes of Industrial Metaverse are given at the end as well as the challenges from technology, industry and application.
