The Metaverse industry is developing rapidly, and related technologies are being actively improved. Tools such as controllers, keyboards, and mouses are used to interact in the Metaverse, but they are not natural and intuitive interfaces to resemble real-world interactions. Immersive interaction in a Metaverse space requires the engagement of various senses such as vision, touch, and proprioception. Moreover, in terms of body senses, it requires a sense of body ownership and agency. In addition, eliciting cognitive and emotional empathy based on non-verbal expression, which cannot be suitably conveyed to the digital world, requires higher-level technologies than existing emotion measurement solutions. This diversity of technologies can converge to build an immersive realistic Metaverse environment. We review the latest research trends in technologies related to immersive interactions and analyze future development prospects.

Wearable metaverse devices have sparked enthusiasm as innovative virtual computing user interfaces by addressing a major source of user discomfort, namely, motion-to-photon latency. This kind of latency occurs between the user motion and screen update. To enhance the realism and immersion of experiences using metaverse devices, the vergence-accommodation conflict in stereoscopic image representation must be resolved. Ongoing research aims to address current challenges by adopting vari-focal, multifocal, and light field display technologies for stereoscopic imaging. We explore current trends in research with emphasis on multifocal stereoscopic imaging. Successful metaverse visualization services require the integration of stereoscopic image rendering modules and content encoding/decoding technologies tailored to these services. Additionally, real-time video processing is essential for these modules to correctly and timely process such content and implement metaverse visualization services.

The metaverse is expected to evolve into an immersive environment based on photorealistic stereoscopic imaging to integrate real and virtual worlds. To transition from flat images to immersive stereoscopic images, such as light fields and holograms, a continuous cycle of technological development should be reached in media, content, and device technologies, ranging from acquisition and generation to transmission and synthesis as well as reproduction and interaction. Additionally, owing to the multitude of components involved in the metaverse, proper service realization will be challenging without concurrent advancements in computing and communication technologies that facilitate the integration of such components. We introduce research and development trends in media, contents, and devices at the Electronics and Telecommunications Research Institute toward the next generation of stereoscopic images.

Along with the transition to the fourth industrial revolution, the possibility of metaverse-based innovation in the fashion field has been confirmed, and various applications are being sought. Therefore, this study performs meaning structure analysis and discusses the prospects of meta fashion using big data. From 2020 to 2022, data including the keyword "metaverse + fashion design" were collected from portal sites (Naver, Daum, and Google), and the results of keyword frequency, N-gram, and TF-IDF analyses were derived using text mining. Furthermore, network visualization and CONCOR analysis were performed using Ucinet 6 to understand the interconnected structure between keywords and their essential meanings. The results were as follows: The main keywords appeared in the following order: fashion, metaverse, design, 3D, platform, apparel, and virtual. In the N-gram analysis, the density between fashion and metaverse words was high, and in the TF-IDF analysis results, the importance of content- and technology-related words such as 3D, apparel, platform, NFT, education, AI, avatar, MCM, and meta-fashion was confirmed. Through network visualization and CONCOR analysis using Ucinet 6, three cluster results were derived from the top emerging words: "metaverse fashion design and industry," "metaverse fashion design and education," and "metaverse fashion design platform." CONCOR analysis was also used to derive differentiated analysis results for middle and lower words. The results of this study provide useful information to strengthen competitiveness in the field of metaverse fashion design.

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.

Web 3.0 is a new web paradigm that aims to overcome the excessive commercialism and influence of big tech companies. Web 3.0 can be defined as a user-centered decentralized Internet environment, and Web 3.0 is a mixture of various terms and technologies such as blockchain, cryptocurrency, NFT, artificial intelligence, and metaverse. When new technology fields emerge, it is common to have positive and negative evaluations. As a result, rather than deciding which position is correct, it is necessary to investigate the causes and directions of change and prepare to seize the opportunity. In light of this, the present study examines the change in the web paradigm and the context of the emergence of Web 3.0, investigates the characteristics and major cases of Web 3.0, and discusses future issues and prospects.

In this study, we investigate the trends and prospects of spatial light modulation (SLM) technology that enables full complex modulation as a next-generation SLM. Current SLM technology, which is used as a key element in holography, augmented reality (AR), XR, and realistic displays, has performance limits that modulate only amplitude or phase. Notably, SLM capable of full complex modulation does not produce diffraction noise, unlike DC and twin image, and thus has a high-efficiency performance. In the future, the application field of next-generation SLM, which can be full-complex modulated, is expected to cover a wide range of holography-AR and-XR devices, optical artificial intelligence, and 6G free space optics communications, which will greatly contribute to the development of a super-realistic metaverse platform and service.
