This research is to understand customer satisfaction with virtual fitting based on a 3D body scanner and avatars as well as differences between avatars and the 'real me'. To this end, this research examined Korean college students to facilitate 3D body scanning, avatar generation and surveys. The author used 3D body scan data with direct measurements to identify differences between the 3D body scan data-based 'my avatar' and 'real me' in the virtual dress fitting system. The survey results on 'the level of customer awareness on 3D body scanner' found that the majority of both genders did not know about it and indicated a lower usability to incorporate IT technology into the fashion industry. The question in the 3D body scanning and avatar found an affirmative attitude. Satisfaction levels on the 3D avatars' similarity with 'own body' and garment fitting were positive and indicated a need for further technological improvements to express the avatars identical to customers' own body. More research is necessary for the accuracy of sizes for 3D body scanning that measure body sizes while wearing clothes. Avatars based on such datamay be less similar to 'own body' and cause customer dissatisfaction. Thus, further technology development is required to narrow gaps using data to make avatars that provide more accurate virtual fitting simulation services to customers.

As interest in the metaverse has grown, there has been a demand for avatars that can represent individual users. Consequently, research has been conducted to reduce the time and cost required for the current 3D human modeling process. However, the recent automatic generation of 3D humans has been focused on creating avatars with a realistic human form. Furthermore, the existing methods have limitations in generating avatars with imbalanced or unrealistic body shapes, and their utilization is limited due to the absence of datasets. Therefore, this paper proposes a new framework for automatically transforming and creating stylized 3D avatars. Our research presents a definitional approach and methodology for creating non-realistic character avatars, in contrast to previous studies that focused on creating realistic humans. We define a new shape representation parameter and use a deep learning-based method to extract character body information and perform automatic template mesh transformation, thereby obtaining non-realistic or unbalanced human meshes. We present the resulting outputs visually, conducting user evaluations to demonstrate the effectiveness of our proposed method. Our approach provides an automatic mesh transformation method tailored to the growing demand for avatars of various body types and extends the existing method to the 3D cartoon stylized avatar domain.

This research project investigates the differences of various body locations (between 3D body models) and drapes garments digitally onto 3D body models. Three different subject models will be given explication. It consisted of (1) data collection of three-dimensional scans (2) creation of 3D body representations (3) comparison of avatar shapes and measurements (4) visualization and assessment of 3D body models and their 3D virtual garments. The study tests a theory of impact by differences in avatars by pattern design. A visual inspection of avatars showed clear differences between the six avatar types (in the generating process); however, there was notably less difference between 3D garment simulations based upon the six avatars produced. This demonstrated that there was less influence on the 3D garments than was predicted after a visual inspection of the avatars.

Recently, the virtual world where avatars are playing crucial roles in connecting users with each other receives much attention from practioners as well as academicians. Especially, Second Life is one of the most prevailing website where 3-D avatars can be easily designed in line with for users' personal tastes. However, there are no studies showing how the selling agents designed in 3-D avatars can affect customer trust and purchase intention in the context of virtual world. This study is concerned with suggesting the empirical results to fill in the research void like this. Results reveal that the proposed hypotheses are proven with statistical significance.

This study aims to use the avatar sizing system of the 3D apparel CAD program instead of the existing 3D body scanners, and to commercialize 3D personal avatars. Towards these ends, the study examined a difference between a 3D avatar and actual body was determined to verify the 3D avatar sizing system. For the experiment, three subjects were selected, were measured as they were, and were made to undergo 3D body scanning and photographing. Then, using avatar sizing system on the 3D apparel CAD program, three types of virtual bodies, namely 3D avatars. The 3D avatar and actual body measurements were compared, and 3D avatars and 3D body-scanned shapes were likewise compared. As a result, the three types of actual bodies and their 3D avatars that were created based on the sizing system of the 3D apparel CAD program were overall similar. but, the thin body-YY type and the normal body-A type were different from their avatars. In the case of type B, who had a bulging abdomen, the 3D avatar was bigger than the actual body as measured. Also, in all body shapes, the girths around the chest, waist and abdomen were produced with exaggerated muscular amounts compared to their actual muscular amounts.

On-line avatar community service requires natural representation of communication, emotional expression, and popular dances and various kinds of services. The space should be dynamic, and the interaction between the motions of avatars and the space is required. The avatars with their national, interesting, and various motions should be implemented togetherwith interaction with virtual spaces, in order to have competition in developing 3D avatars. It is expected for 3D avatars to be broadly applied for 3D shopping malls for e-commerce, cyber model houses, 3 D simulations, and 3D virtual reality game. Therefore, for one line 3D avatar community services, we try to provide the scheme for making interactive virtual spaces, together with 3D avatar animations.

Fashion industry has tried to adopt the virtual garment technology to reduce the time and effort spent on sample creation. For garment manufacturers to adopt the virtual garment technology as an alternative to sample creation, 3D avatars that meet the needs of each brand should be developed. Virtual garment softwares that are available in the market provide avatars with standardized body models and allow to modify the size by manually entering size specifications. This study proposed a methodology to develop size specifications for 3D avatars as well as brand-customized production sizes. For this, a man's fashion brand which is using virtual garment technology is selected. And the Size Korea database is used to develop size specification based on the customers' body shape. This study developed regression equations on body size specifications, which in turn proposed a regression model to proportionately change size specifications of 3D fitting-models. Based on the each body size calculated by the regression model, a standard model is created, and the skeleton-skin algorithm is applied to the regression model to obtain the results of size changes. Then, the 3D model sizes are tested for size changes as well as measured, which verifies that the regression model reflects body size changes.
