Fashion design in the metaverse is not simply a 3D avatar or virtual fashion, it is an important clue for shopping trends, and the role of fashion design has grown even more because avatars and humans are identified and active. This study, I attempts to understand the metaverse platform accurately and find out the scope of fashion design within the metaverse platform. In addition, we want to provide basic data that can expand the field by using fashion design in various ways on the metabus platform. This study investigated and analyzed various metaverse fashion cases, articles, software, and methods used by metaverse fashion creators, and the results are as follows. First, the metaverse platform is a new level of virtual interaction where users and creators communicate through the convergence of augmented reality, lifelogging, mirror world, and virtual world. Second, most of the users of the metaverse platform are generation Z, and metaverse creators who make money by producing avatars or items, including fashion design, are emerging as a new job field. Third, many fashion brands created spaces on the Metaverse platform, collaborated with games, or opened fashion weeks for publicity, marketing, and sales. Fourth, as a 3D program for metaverse fashion creator activities, open-source software is easier and free of charge compared to programs for fashion design specialists, and most costumes can be reproduced, so it will be easier for fashion design majors to utilize.

As the digital fashion show developed through the pandemic period, this study analyzed the literature on the digital fashion show and presented basic data for the design of the metaverse fashion show space. Through keyword analysis, the flow of research was identified, and implications for space design for the metabus fashion show were derived through analysis of space, models and avatars, lighting, and communication. Through keyword analysis, it was possible to understand the conversion process of digital fashion show research in the pandemic situation. Metaverse fashion shows can express stages, avatars, and costumes that are impossible in the real world, but require design considering expressiveness. In the metaverse space, communication can be thought of as a designer's value delivery, digital marketing, and communication with customers.

Emojis and avatars are widely used in online communications, but their emotional conveyance lacks research. This study aims to contribute to the field of emotional expression in computer-mediated communication (CMC) by exploring the effectiveness of emotion recognition, the intensity of perceived emotions, and the perceived preferences for emojis and avatars as emotional expression tools. The following were used as stimuli: 12 photographs from the Yonsei-Face database, 12 Memojis that reflected the photographs, and 6 iOS emojis. The results of this study indicate that emojis outperformed other forms of emotional expression in terms of conveying emotions, intensity, and preference. Indeed, the study findings confirm that emojis remain the dominant form of emotional signals in CMC. In contrast, the study revealed that Memojis were inadequate as an expressive emotional cue. Participants did not perceive Memojis to effectively convey emotions compared with other forms of expression, such as emojis or real human faces. This suggests room for improvement in the design and implementation of Memojis to enhance their effectiveness in accurately conveying intended emotions. Addressing the limitations of Memojis and exploring ways to optimize their emotional expressiveness necessitate further research and development in avatar design.

The metaverse is a virtual world where individuals engage in social, economic, and cultural activities using avatars, which represent an alternate version of oneself within the virtual realm. While the metaverse has garnered global attention recently, research exploring the identity manifested through avatars within the metaverse remains limited. This study investigates the influence of four IT artifact characteristics related to avatar usage in the metaverse-avatar representation, avatar copresence, avatar profiling, and avatar-space interaction-on perceived avatar identity verification. A survey was conducted with 196 experienced users of the Zepeto platform, and hypotheses were tested using structural equation modeling. The analysis results indicate that the use of IT artifacts enabling avatar representation, avatar copresence, and avatar-space interaction has a positive impact on perceived avatar identity verification. This achieved self-verification indirectly influences the satisfaction and subsequent intention to continue using the metaverse. This study contributes to the academic field by empirically verifying the metaverse technological factors that influence the projected identity onto avatars within the metaverse. Furthermore, it is expected to provide effective guidelines for metaverse platform companies in designing and implementing the metaverse.

This study proposes a rigid-body tracking based virtual avatar application method to increase the social presence and provide various experiences of virtual reality(VR) users in an immersive virtual environment. The proposed method estimates the motion of a virtual avatar through inverse kinematics based on real-time rigid-body tracking based on motion capture using markers. Through this, it aims to design a highly immersive virtual environment with simple object manipulation in the real world. Science experiment educational contents are produced to experiment and analyze applications related to immersive virtual environments through virtual avatars. In addition, audiovisual education, full-body tracking, and the proposed rigid-body tracking method were compared and analyzed through survey. In the proposed virtual environment, participants wore VR HMDs and conducted a survey to confirm immersion and educational effects from virtual avatars performing experimental educational actions from estimated motions. As a result, through the method of utilizing virtual avatars based on rigid-body tracking, it was possible to induce higher immersion and educational effects than traditional audiovisual education. In addition, it was confirmed that a sufficiently positive experience can be provided without much work for full-body tracking.

A 2D comic model, a comic-style line drawing model having only eyebrows, eyes, nose and mouth, is much easier to generate facial expressions with small number of points than that of 3D model. In this paper we propose a 3D emotional editor using a 2D comic model, where emotional expressions are represented by using action units(AU) of FACS. Experiments show a possibility that the proposed method could be used efficiently for intelligent sign-language communications between avatars of different languages in the Internet cyberspace.

This study aims to examine the realistic self-esteem of adolescents and perception of adolescents toward avatar in an attempt to understand basic aspects of their distinctive lifestyle fundamentally relative to the cyber culture on the web, given that the adolescent which is significant in forming self-esteem period plays an important role in the psychological aspect of adolescents. As for method of research, this study analyzed the self-esteem of users, their preference for avatar, and the perception toward avatar, in order to understand their psychological and social maturity. The result of study indicated that the increased self-esteem in reality among the adolescents led to the increased preference for avatar relative to the cyber culture on the web, which in turn increased the recognition of others' avatars. Those findings suggest that adolescents tend to assign self-esteem to avatar as great as themselves. Thus, it may be important to help adolescents form their self identity from the perspective psychological maturity, so that a sound and healthy web culture can be formed depending on the formation and level of self-esteem among adolescents.

We have made knitwear in a different way from the typical woven pattern; it does not have the dart, even for women's tops. The purpose of this research was to compare the fit and appearance of the torso pattern for circular knitted fabric between virtual try-on garments and real garments. First, a woman in her 20's was scanned by a 3D body scanner, and thus producing a virtual avatar. I prepared knit patterns and created a torso pattern appropriate for circular knitted fabric. Next, I measured the body size of the avatar. The 2D patterns for the torso and sleeves were developed using the Yuka Super ALPHA : Plus. The 3D virtual garments were made from the imported 2D patterns and were then tried on the 3D virtual avatars. Finally, the fit of the real garments and the virtual garments was compared. While the shape of the virtual try-on garments were similar to the real garments, the folding and sagging were different. This study found the length was the same as woven wear. However the actual bust size and the clothing size were the same which is not a typical characteristic of woven wear. In the case of hem measurement, more space was needed than actual body size but less space was needed than in woven patterns.

In this paper, we propose a texture generation scheme for 3D avatars from three or more human face photos. First, we manually mark image positions corresponding to vertices of a given UVW map. Then, a face texture is automatically generated from the photo images. The proposed texture generation scheme extremely reduces the amount of manual work compared with the classical methods such as Photoshop-based schemes. The generated textures are photorealistic since the textures fully reflect the naturalness of the original photos. The texture creation scheme can be applied to any kind of mesh structures of 3D models and mesh structures need not be changed to accommodate the given textures. We created face textures from several triplets of photos and mapped them to 3D avatar faces. Experimental results showed that visual realism of avatar faces is much enhanced by the face textures.
