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.

The 3D virtual fitting system is a new and very efficient system replacing real fitting in apparel industry and on-line shopping. It is a win-win system for both of consumer and manufacturer which not only reduces design and production time but also resolves consumer's complaints by checking the wearing image beforehand. It is a must-have item in the future. The purpose of this study is to analyze sizing menu, terms, and current status and to figure out problems of avatar sizing programs which substitute human bodies in virtual fitting. We chose three existing outstanding programs in domestic and global market, compared and analyzed the program, manual, and terms that are used in avatar sizing, and investigated the strengths, weaknesses, problems of options and terms and finally suggested an alternative terms. The revealed problems are as follows: each program supports various avatars ranging from male to female, from child to adult, and from oriental style to western style. The image of the avatar could be changed through the options for hair style, shoes and accessories. But we found out some problems. The avatar body types are far from actual human body types, avatar sizing menus and item terms are different from program to program, and terms not yet standardized. Cooperative efforts of industry and academy on standardization of sizing menus and terms should be emphasized for the virtual fitting system to be widely used like the other computer graphic programs or word editors.

This study provide basic data to develop a dress form reflecting body shape characteristics by age and to produce a 3D body form in a virtual fitting program. A comparative analysis was conducted on the size, section shape, and slope of side shape of the modeling form by the sizing of the basic female avatar in CLO 3D, one of the 3D apparel CAD programs and the body form of women in their 20s-50s by body shape in the 6th Size Korea (2010). First, all the differences were formed similarly in the direct measurements between the 3D avatar and the body form were within 1 mm. Second, in a comparison of the section form of the avatar and body form in Size Korea, the avatar was formed in straight body shape and did not reflect a spinal curvature according to age. As a result of an examination of the items with a difference over 5° in the slope of side shape, there were angle differences in numerous body shapes in the angles of the side upper abdomen, side upper back, and side upper bust, and the avatar's bust shape was expressed more flatly compared to body form. It will be possible to produce an avatar that can adequately reflect body shape characteristics by adding detailed length and angle items by the region like waist back length and front length in producing the avatar reflecting body shape characteristics, instead of a standard body shape.

The purpose of this study is to create a 3D avatar from 3D human body shape data using the CLO 3D virtual clothing program and to verify the feasibility of avatar production using the virtual clothing system for verifying size and shape. The research method was to select one virtual representative model that is the closest to the mean size of each body item for each age group. Using the 3D human body scan shape of a 40-69 years old male was applied to the CLO 3D virtual wearing system. Using the CLO 3D Avatar conversion menu, we verified the feasibility of creating a 3D avatar that reproduces the human body scan shape. In the dimension comparison between the 3D avatar and the fictitious representative model, the dimension difference was noticeable in height, circumference, and length. However, as a result, the converted 3D avatar showed less than a 5% difference in most human dimensions. In addition, since the body shape and posture were reproduced similarly, the utilization of the avatar was verified.

In the virtual fitting system, the use of a 3D avatar is not a simple garment model, but it should be able to reproduce the size and shape of the customer using a fitting system. Although various virtual fitting systems have their own 3D avatar sizing systems and provide 3D avatars that match the size of the customer, there are limitations in realizing the actual body shape in actual use by the consumer. The purpose of this study is to realize a 3D avatar with excellent size and conformity for customer use. Therefore, this study aims to provide basic data for the formation of a 3D standard avatar of Korean women aged in their 20's, by comparing and analyzing the degree of the consumer user friendly system change of a body type, and the consumer's ability in selecting a consumer representative body type. Based on the survey data of 'Size Korea' conducted from 2004 to 2015 at three times, we examined the change of body shape over 10 years. Then, based on the results of 6th and 7th data, 4 factors of the concurrent body shape change of women of the consumer demographic studied were selected through the use of a factor analysis. Following this analysis, the 4 extracted factors were clustered again and finally released 7 representative body types, which were obtained based on height and weight. The size of each representative figure is derived by the use of a regression analysis, and it is used as a basic data for 3D avatar formation of the virtual fitting system.

This study analyzed a somatotype that was more suitable to a virtual fitting model and to improve the reality of a virtual model size. We analyzed 1,868 women 18-59 years old from the 6th Size Korea data. First, factor analysis was done for abstracting new criteria for dividing the somatotype; subsequently, we selected the waist height proportion to stature (body proportion) and drop (torso shape). Next, the cluster analysis was done with these criteria and 7 body proportion types and 11 torso shapes were distinguished. A virtual model size for the most common somatotype was also developed by a regression analysis of constituting sizes of each factor that was compared with body sizes well as with Clo's virtual model size. The model of this research showed a high similarity in sizes with body as well as improved better realisty than the Clo model which presented size problems such as longer limbs, bigger bust, smaller waist and a smaller arm circumference than the real body.

This study analyzed a somatotype of teenager's that was suitable to improve the reality of a virtual model size. We analyzed 843 teenagers 12-18 years old from the 6th Size Korea data. First, factor analysis was done for abstracting new criteria and dividing the somatotype; subsequently, we selected the waist height proportion to stature (body proportion) and drop (torso shape). Next, the cluster analysis was done with these criteria; subsequently, 5 body proportion types and 7 torso shapes were distinguished. A virtual model size for 4 somatotype with more than 50 persons was also designed by a regression analysis that constituted sizes for each factor. The designed model size was compared with body size as well as with Clo's virtual model size. The research model showed a high similarity in sizes with body as well as improved reality over the Clo model that presented size problems such as low waist height, bigger bust, and smaller thigh circumference than the real body.
