The "metaverse" refers to a three-dimensional virtual realm that provides immersive experiences to users through their avatars. In a metaverse, consumers can interact with other users and engage in real-life activities using their avatars. These avatars are visual depictions of the user with realistic or unrealistic animated features. This study investigates how the rendering quality of virtual stores in a metaverse, serially mediated by embodied presence and enjoyment, can increase the use intention of metaverse shopping platforms. Additionally, this study explores how avatar realism moderates relations between the rendering quality and embodied presence. An experimental study was conducted using a between-subjects design to investigate the effect of metaverse media richness through avatar realism (realistic vs. unrealistic). Participants were randomly allocated to view a stimulus, and a total of 205 valid responses were analyzed using AMOS 23.0 and SPSS Process Macro 4.0. The results suggest that the rendering quality has a greater impact on embodied presence, particularly when consumers experience environments featuring realistic avatars. In conclusion, high rendering quality and realistic avatars within the metaverse space enable consumers to experience greater enjoyment and more actively engage with metaverse shopping platforms.

In various fields such as art, design, music, film, sports, games, and fashion, NFTs (Non-Fungible Tokens) are creating new economic value through trading platforms dedicated to NFT art and content. In this article, I analyze the current state of blockchain technology and NFT art content in the context of an expanding market for blockchain-based NFT art content in the metaverse. I also propose several tasks based on the economic and industrial logic of technological innovation. The first task proposed is to integrate cultural arts on blockchain, metaverse, and NFT platforms through digital innovation, instead of separating or distinguishing between creative production and consumption. Before the COVID-19 pandemic, there was a clear separation between creators and consumers. However, with the rise of Web 3.0 platforms, any user can now create and own their own content. Therefore, it is important to promote a collaborative and integrated approach to cultural arts production and consumption in the blockchain and metaverse ecosystem. The second task proposed is to align the legal framework with blockchain-based technological innovation. The enactment and revision of relevant laws should focus on promoting the development of the NFT trading platform ecosystem, rather than merely regulating it for user protection. As blockchain-based technology continues to evolve, it is important that legal systems adapt to support and promote innovation in the space. This shift in focus can help create a more conducive environment for the growth of blockchain-based NFT platforms. The third task proposed is to integrate education on digital arts, including metaverse and NFT art contents, into the current curriculum. This education should focus on convergence and consilience, rather than merely mixing together humanities, technology, and arts. By integrating digital arts education into the curriculum, students can gain a more comprehensive understanding of the potential of blockchain-based technologies and NFT art. This article examines the digital technological innovation such as blockchain, metaverse, and NFT from an economic and industrial point of view. As a limitation of this research, the critical mind such as philosophical thinking or social criticism on technological innovation is left as a future task.
