I. Introduction
Metaverse, the convergence of physical and digital realities towards the virtual world, has recently become of great interest in the technological industry and research community [1]. The emergence of the Metaverse has been facilitated by the rapid advancements of blockchain, augmented reality, virtual reality, the Internet of Things, and distributed computing [2]. Recently, Facebook Inc. has rebranded itself as “Meta” to accelerate the realization of the Metaverse. This transformation aims to create an immersive environment where people can surpass their own personal and career growth expectations. Initially, the concept of Metaverse was focused on the convergence of physical and digital realities with less realizing the needs and interests of human beings. Later, the concept of a human-centric Metaverse has been introduced, which emphasizes the concerns of human beings. The ultimate goal is to enhance and enrich human lives with meaningful customized experiences. By prioritizing the human aspect, the human-centric Metaverse aims to create a user-centered virtual realm that provides valuable experiences and opportunities [3].
