  In the era of the Web of Things, the Metaverse is expected to be the landing
site for the next generation of the Internet, resulting in the increased
popularity of related technologies and applications in recent years and
gradually becoming the focus of Internet research. The Metaverse, as a link
between the real and virtual worlds, can provide users with immersive
experiences. As the concept of the Metaverse grows in popularity, many scholars
and developers begin to focus on the Metaverse's ethics and core. This paper
argues that the Metaverse should be centered on humans. That is, humans
constitute the majority of the Metaverse. As a result, we begin this paper by
introducing the Metaverse's origins, characteristics, related technologies, and
the concept of the human-centric Metaverse (HCM). Second, we discuss the
manifestation of human-centric in the Metaverse. Finally, we discuss some
current issues in the construction of HCM. In this paper, we provide a detailed
review of the applications of human-centric technologies in the Metaverse, as
well as the relevant HCM application scenarios. We hope that this paper can
provide researchers and developers with some directions and ideas for
human-centric Metaverse construction.
