In today's modern fashion industry, along with the Fourth Industrial Revolution, the digital fashion industry using new technologies such as AR (Augmented Reality), VR (Virtual Reality), and Metaverse is gradually expanding. Accordingly, in the field of fashion design education, a new form of fashion illustration using VR technology is attracting attention as a new expression method. Recently, the use of digital tools such as iPads is gradually increasing in the field of education at universities majoring in fashion design, and students' interest in new digital tools is continuously increasing in the process of fashion illustration work. Therefore, this study implements fashion illustration using VR technology, which has been commercialized and popularized in the fashion industry, analyzes the differentiated characteristics compared to fashion illustration completed with iPad, and explores the possibility of using VR technology for fashion illustration as a new expression tool. We looked at the limitations. Through this study, it was found that VR is a positive help to fashion illustration to express the conception and overall connectivity in the three-dimensional aspect of fashion design, and the iPad was found to be suitable for specific and delicate fashion illustration expression. The results of this study are intended to provide basic data for fashion illustration education that can increase students' interest and achievement.

Recent developments in computer graphics technology and image processing technology have increased interest in point cloud technology for inputting real space and object information as three-dimensional data. In particular, point cloud technology can accurately provide spatial information, and has attracted a great deal of interest in the field of autonomous vehicles and AR (Augmented Reality)/VR (Virtual Reality). However, in order to provide users with 3D point cloud contents that require more data than conventional 2D images, various technology developments are required. In order to solve these problems, an international standardization organization, MPEG(Moving Picture Experts Group), is in the process of discussing efficient compression and transmission schemes. In this paper, we provide a region division transfer method of 3D point cloud content through extension of existing MPEG-DASH (Dynamic Adaptive Streaming over HTTP)-SRD (Spatial Relationship Description) technology, quality parameters are further defined in the signaling message so that the quality parameters can be selectively determined according to the user's request. We also design a verification platform for ROUTE (Real Time Object Delivery Over Unidirectional Transport)/DASH based heterogeneous network environment and use the results to validate the proposed technology.

인공 지능, 사물 인터넷, 클라우드 컴퓨팅, 빅데이터, 모바일을 중심으로 시작된 4차 산업혁명은 최근 메타버스(Metaverse)시대로 자연스럽게 확장되어 가고 있다. 메타버스 시대의 핵심 기술인 VR(Virtual Reality)/AR(Augmented Reality)/MR(Mixed Reality)과 이를 디스플레이 하기 위한 HMD(Head Mounted Display)나 글래스(glass) 장치들은 사용자에게 고품질 영상뿐만 아니라 3차원 공간에 대한 6DoF(Degrees of Freedom)급의 자유도를 제공해야 한다. 이에 발맞춰 MPEG에서는 최근 실사 및 CG(Computer Graphics)로 제작된 다시점 텍스쳐 및 깊이 영상에 대한 효과적인 압축 방법을 찾기 위한 MIV(MPEG Immersive Video) 표준화를 진행중이다. 본 논문은 최신 2차원 압축 표준인 VVC(Verstitle Video Coding)를 기반으로 MPEG MIV 1.0 표준 프레임워크를 검증해본다. 특히 높은 압축율에 비해 복잡도가 높은 VVC 표준의 특성을 고려하여 HHI에서 개발한 최적화 코덱인 VVenC를 이용하여 압축 효율과 복잡도 관점에서 MIV 표준 활용을 위한 최적의 솔루션을 찾고자 한다.

In this paper, we propose an extended reality-based simultaneous multi presence system in a process of remote cooperative work. The proposed system generates a ring-shaped invisible screen which surrounds a user, and it provides position and manipulation of remote workspace and personal workspace. With the proposed system, the user easily navigates the several workspace for the remote collaboration or he/she selects a specific space for immersion. The proposed system also provides manipulation of personal workspace for the user during the remote cooperative work. We conducted a user study to prove effectiveness of the proposed system. According to the results, the proposed system increased understanding spatial information and usage of time during the remote cooperative work.

In this study, we developed the service that can efficiently making friends among college students in metaverse world. Metaverse technology has recently emerged as an important topic across the industry.' The development of virtual and augmented reality technologies, which have emerged as a new paradigm to drive the next generation of the Internet, is bringing us closer to the metaverse world. Metaverse is spreading around the gaming, entertainment, music, and content industries[1]. In particular, as non-face-to-face transitions have accelerated since the COVID-19 outbreak, lifestyles and industrial sites are rapidly changing beyond untacting to metaverseization, a three-dimensional virtual space. After discovering the needs of users through surveys and interviews, the research method added functions to the service that matched those needs. Users were pleased that they could make friends who matched their preferences and tastes, play like a game in a virtual world called metaverse, and customize their avatars to their liking. It was also very fresh to customize the goods so that they could be gifted and kept by themselves.

This study focuses on enhancing the understanding of the form and characteristics of traditional towers, or 'pagodas,' by utilizing WebXR technology to enable users to explore 3D models and experience them in virtual reality on the web. Traditional towers in Korea pose challenges for direct on-site verification due to their size, making it difficult to examine the structure and features of each level. To address these issues, this research aims to provide users with a WebXR service that allows them to remotely explore and analyze towers without geographical or temporal constraints. The research methodology involves utilizing WebAR to offer a web-based service where users can directly view the original form of the tower's 3D model using smart devices both online and on-site. However, outdoor conditions may affect performance, and to address this, a tower-outline detection and matching technique was employed. Consequently, we propose a remote support service for traditional towers, allowing users to remotely access information and features of various towers nationwide on the web. Meanwhile, on-site visits can involve experiencing augmented reality representations of towers using smart devices.

Recently, VR and AR are emerging as an area of interest in ICT. In virtual reality to feel like a real, many people are looking for them because of its charm. However, the motion of the VR image and the moving object are not synchronized exactly, and a problem of feeling nausea is also occurring. The problem should be solved by the application of Attraction in the VR system. In this paper, we propose a module that minimizes delay time by synchronizing movement of VR image and moving object. The proposed module calculates the moving distance using the direction and the acceleration sensor that the user views through the VR device. The module proposed in this paper will pay attention to the fact that the movement of the attraction moves along a fixed path, so that the accurate travel distance can be calculated.

This study aims to examine the trends in Metaverse technology following the Post-COVID era and analyze the use cases in the jewelry industry. With the endemic, the business environment for companies has shifted from online to offline, leading to a reduced public interest in the Metaverse. However, examining the global jewelry brand trends in metaverse technology reveals advancements in AR/VR technologies that enhance realism and evolve the metaverse into a space without the uncanny gap between virtual and reality. The Metaverse exhibits three main characteristics in the Post-COVID era. First, there is a transformation in the business domain, starting with digital twins. Second, it is integrating with various information and communication technologies. Third, setting a direction for Metaverse operation as an omni-channel is being emphasized. Utilizing assets learned during the COVID-19 period and continuing to learn about digital and online technologies is essential for securing market competitiveness. This paper discusses how to enhance the competitiveness of jewelry industry entities based on the trends of Metaverse technology in the Post-COVID era.
