The word "Metaverse" is made up of "meta" (beyond) and "verse" (universe), which means the concept of the universe and life with a perspective outside the real universe. The concept originates from the daring imaginations of science fiction writers, and the term was coined in Neal Stephenson's 1992 science fiction novel named “Snow Crash”, where humans can interact with each other and with software agents in a cyberpunk-like 3D space. According to Wikipedia, the exact definition of Metaverse is described as follows:“Metaverse is a collective virtual shared space that encompasses all virtual worlds and the Internet. It may contain derivatives or replicas of the real world, but it is distinct from augmented reality. The term is often used to describe the concept of a future iteration of the Internet, made up of shared, continuous 3D virtual spaces linked together into a perceived virtual universe. awake ".It will take time for the Internet to evolve into the Metaverse, but the Metaverse, as the future direction of the Internet, remains imaginative and engaging. As a result, leading companies and organizations worldwide have long deployed Metaverse on every aspect, hoping to seize the opportunity for the next version of the Internet.
