The purpose of this study was to compare fitting of the upper garment by brassiere cup size and types of bodice block. This study conducted a 3D virtual garment system by applying three types of bodice block (I, II, III) and experimental pattern of the bodice block to 3D avatars of four individuals with the following measurements: under bust circumference of 73.5 cm and bust circumferences of 83.5 cm, 86.0 cm, 88.5 cm, and 91.0cm. The results of the study were as follows. First, for 83.5 cm bust circumference (A Cup), appearance of the three types of bodice block (I, II, III) was appropriate. However, as bust circumference increased in size, shape became inappropriate. The depth and width of the armhole, within 15 cm and 11 cm, respectively, were found to be appropriate. In case of 91.0 cm bust circumference (D Cup), all three bodices (I, II, III) were inappropriate. Second, the results of the draft of the experimental patterns of the bodice block of bust circumference measuring 83.5 cm, 86.0 cm, 88.5 cm, and 91.0 cm in the 3D avatars of the four individuals revealed similarities in the frontal view of the silhouette in the four avatars; in the case of the lateral view of the silhouette, lateral width grew wider as bust circumference of the silhouette became larger, but the shape of armhole showed no changes. The depth of the armhole showed little changes from 15.1 cm to 15.22 cm, and the height of sleeve (armscye depth 13.6 cm within +2 cm) remained similar. The difference in width of the armhole from 11.26 cm to 11.37 cm was rather small. The width of the upper sleeve (8.97 cm) seemed to be appropriate as it remained within the 2-3 cm boundary.

Avatars are a visual representation of users in a virtual world such as an MMORPG. These avatars are often seen as representations or idealizations of the user's actual self. However, this view does not account for the prevalence of two behaviors: multiple avatars and 'gender swapping'. An exercise and questionnaire were created to study avatar customization practices across players outside the context of any particular game to understand better user motivations in creating their virtual selves. A preliminary trial of the exercise showed little correlation between age or gender and gender swapping. While those of non-traditional sexuality were more likely to gender swap, half of traditional sexuality also swapped. Finally, the personality trait, Openness to Experience, showed promising correlation with gender swapping.

We propose the SoMA(System of Making Avatars) based on a commercial 3D game engine. It first decomposes a given character into assemblable pieces, then gives the user them as prefab components so that he or she can reassemble and/or customize them to be plenty of characters. To accomplish this, it implements the character assembly structure as an hierarchy, the upper levels of which are categorized for gross assembly, and the lower levels of which are parameterized for detailed customization. It also defines a hierarchical naming convention for ease of access to the structure. Finally, it provides body, clothes, and attachment systems to make relevant characters.

Developing 3D games of quality is getting easier as commercial game engines have significantly evolved. It is still difficult, however, for entry-level developers to create various avatars which could affect the entire game because it requires expertise in 3D design and programming. We propose a design of an avatar assembly system based on a commercial game engine, Unity. It includes the assembly, customization, and management of avatars. It also provides an avatar update mechanism via the World Wide Web(WWW) provided by Unity's asset system so that various avatars can be supplied after the initial game distribution.

With the advent of the non-face-to-face era, a new type of digital sexual crime with avatars is emerging on the Metaverse virtual reality platform. Due to the lack of clearly established in legal and regulatory systems, it is challenging to punish offenders and acquire digital proof for sexual crimes using these avatars. This research aims to suggest a service and technological solution is development platform that may assist crime prevention and the collection of digital evidence, with a particular emphasis on digital sex crimes that occur in the metaverse, a virtual reality realm. This study explores the reasons behind the difficulty of legal application in the metaverse and then determines the types of digital sex crimes that may occur in the metaverse. In addition, it is suggested what service components the metaverse should contain from the stage of construction and design, can be utilized what element of metaverse in order to prevent illegal activity of avatars.

This study aims to analyze consumers' purchase decision-making process of buying avatar fashion items on the Metaverse platform. Drawing on the connection between the self-expression tendency of the MZ generation and that of avatars in the Metaverse, this study uses a qualitative research method to analyze how consumers express their self-image through the appearance of their avatars. Unlike previous studies on the clothing purchase decision-making process, this study shows that purchasing and consumption behavior involve the following six stages: recognizing desire, collecting information, evaluating alternatives, making purchases, evaluating the consumption, and post-purchase action-taking. In the first stage of the purchase decision-making process, consumers' desire arises with self-image expression and confirmation. In the second stage, consumers have a high tendency to shop in the best item category. In the alternative evaluation stage, consumers tend to seek items that match their highest standard while considering their personal preferences. In the fourth stage, when making actual purchases, unplanned purchase behavior often occurs along with an active practice of alternative evaluation. In the fifth stage, the evaluation of the consumption shows that consumers achieve satisfaction by applying a style to their avatars that they are unable to try in the real world. In the last stage, consumers often use their purchases to communicate their various styles with other online consumers. Therefore, we conclude that the online purchase decision-making process differs from the offline process as it is divided into six stages.

The purpose of this study is to produce virtual models of women aged in their 60s and to implement the virtual clothing with jackets. We referred to 3D images of standard and obese body types from the 8^th Size Korea and attempted to create avatars based on their images through the various trials. Final virtual models were made to reflect the appearance of women in their 60s. For the standard body type, a 3D image with average body measurements was selected. Based on numerous trials aimed at turning her image into an avatar, the auto-converted avatar on CLO 3D was slimmer than the woman in the original image, and hence it was not suitable for the virtual model. After blending, we converted the image into an uneditable avatar for which only the joint points could be moved, thereby creating an avatar that was identical to the original image. We also selected an image of an obese woman with a "beer bottle" body shape from the 8^th Size Korea. We created an avatar that resembled her shape by also converting it into an uneditable avatar for which only joint points could be moved. To use these avatars in virtual clothing, we removed masks of avatars and made faces, hair styles, and skin tones representing women in their 60s. The moderately-sized classic jackets were smooth on both virtual models and fitted satisfactorily. This study demonstrated the applicability of virtual model production of various body types or ages in special clothing studies.

The multi-user VR system can more enhance the sense of reality than existing single user VR system, but it also cause a significant problem about network structure and protocol, since the current Internet using TCP/IP can not afford to deliver such a massive information required to the real-time constraint of multi-user VR system. In this paper, we introduce new network structure and protocol for multiple user's virtual world navigation and interaction through their avatars. The virtual worlds are based on virtual building and managed by distributed servers. The avatars have 9 behaviors and recognize the state of each other by pre-defined network protocol.

As digital broadcasting process and information compressing technologies developed, digital technologies have been used extensively in many visual media such as movies and TV programs, and it is required to develop a new process for 3 dimensional digital programs. The study attempts to develop a new digital video-producing process through pre-simulation using a digital storytelling method, in order to increase the quality of broadcasting, reducing the producing time and improve efficiency. This system, supposed to be used to produce actual broadcasting, includes all tools needed for broadcasting in the program, so users can select an appropriate set among the pre-made library, which saves time for making sets. Also, it offers a storyboard making function by perfectly representing the functions of a virtual camera, and enables users to make the better storyboard, checking the real time movies. In addition, it recognizes objects though avatars, organizes the appropriate set for these avatars to act, and embodies a variety of avatar movements through which it reaffirms the camera's position and organization, minimizing errors and saving time and budget.
