In this paper, we propose an interactive genetic algorithm (IGA) to implement an automated 2D avatar synthesis. The IGA technique is capable of expressing user's personality in the avatar synthesis by using the user's response as a candidate for the fitness value. Our suggested IGA method is applied to creating avatars automatically. Unlike the previous works, we introduce the concepts of 'hidden population', as well as 'primitive avatar' and 'simplified genotype', which are used to overcome the shortcomings of IGA such as human fatigue or reliability, and reasonable rates of convergence with a less number of iterations. The procedure of designing avatar models consists of two steps. The first step is to detect the facial feature points and the second step is to create the subjectively optimal avatars with diversity by embedding user's preference, intuition, emotion, psychological aspects, or a more general term, KANSEI. Finally, the combined processes result in human-friendly avatars in terms of both genetic optimality and interactive GUI with reliability.

Since the study by Turkle(1995), the concept of identity play in MMORPGs has been employed primarily to explain the reflection of users' identity in the avatar creation process in online games. This study attempts to conceptualize the identity play of the design process in which the user uses the avatar customizing system to create an avatar in the virtual world. This research verified the model of identity play through players' avatars, a model of the components of identity play constructed. The aims of this study pursued through an analysis of correlations of users' attitudes toward avatars. This study performed structural equation modeling to verify hypotheses about the variables that affect online identity play.

The purpose of present study was to examine the differences in effectiveness of internet apparel advertising using avatars as determined by the avatar involvement. After conducting a pilot test for 35 high school students, final data were collected through a self-administered questionnaire survey from 324 high school students living in Seoul area from July 18 to July 19, 2003; 317 were used for data analysis. Data were analyzed by chi-square analysis, t-test, cluster analysis, descriptive statistics, ANOVA and Duncan's multiple range test. As a result, the subjects were divided into 3 groups based on the level of avatar involvement: high, middle and low involvement groups. There were significant differences in avatar advertising effects among the groups divided by avatar involvement. Those who indicated the higher levels of avatar involvement were more likely to be positive in the cognitive responses, emotional responses, advertising attitude, brand attitude, the stimulus degree of connection, and the recall rates of the brand name. Also, Vector imaging ads were found to be more effective in the brand name recall rates.

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.

Recently, as individual 3D avatars are rapidly generalized in internet sites, its commercial applications for fashion business are being tried in ubiquitous fashion shopping era. In this research, we have investigated and analyzed patent problems of 3D avatar including personal body data to activate the fashion business using 3D avatars. Here, considering the patents for 3D face and body generation methods are already published, this research is focused on whole 3D body avatar obtained from individual body information. Firstly, definition of 3D avatar and its application cases have been investigated and then it has been researched whether or not legal protections by patent law, copyright law, computer program protection law, design protection law and fair competition laws are feasible in view of the subjects to be protected in each law and requirements for such protections. It was revealed that patent law may provide legal protections for 3D avatar and domestic and foreign patents related to 3D avatar have been researched.

As human brands, Idols, the central members of K-pop, are actively engaging in various industries based on the support of their fandoms, greatly impacting the national economy. In particular, due to the development of digital devices and technologies, they are active both online and offline, and idol avatars are a significant part of their activities across diverse contexts. Therefore, this study aims to categorize avatars used in various contexts and explore fandoms' perceptions according to each type. Based on case studies and literature review, idol avatar usage was categorized into products, supplier-led content, and interactive content, and accordingly, surveys and in-depth interviews were conducted. As a result, regardless of category, fandom showed a negative perception of idol avatar usage, as shown in the order of interactive content, supplier-led content, and products. Regarding human brand characteristics of idol avatars, attractiveness was evaluated higher than intimacy and likeability. However, the attachment to real-life idols showed a higher correlation with the characteristics of intimacy and likeability than attractiveness. This study is significant as it looked at the future directions of idol avatar usage by analyzing the fandoms' perception of avatar usage in the K-pop industry from a human brand perspective.

The study of Artificial Life Art has affected the development of art using artificial life. Artificial Life Art started as a concern for microscopic organisms and has developed into works producing some creativities through the choices of spectators. The interests in real animals have resulted in the production of artificial animals such as cyber pets, and the interests in humans have been led to the creation of avatars. We will analyze the invisible emotional field of Naoko Tosa's works which use cyber pets and avatars, and clarify how the creative changes of Artificial Life Art affect the development of interactive art.

This paper presents a method of controlling camera to present virtual space to participating users meaningfully. The users interact with each other by means of dialogue and behavior. Users behave through their avatars. So our problem comes down to controlling the camera to capture the avatars effectively depending on how they interact with each other. The problem is solved by specifying camera control rules based on cinematography developed by film producers. A formal language is designed to encode cinematography rules for virtual environments where people can participate in the story and can influence its flow. The rule has been used in a 3D chatting system we have developed.

The sign-language tan be used a9 an auxiliary communication means between avatars of different languages. At that time an intelligent communication method can be also utilized to achieve real-time communication, where intelligently coded data (joint angles for arm gestures and action units for facial emotions) are transmitted instead of real pictures. In this paper we design a gesture-emotion keyframe editor to provide the means to get easily the parameter values. To calculate both joint angles of the arms and the hands and to goner-ate the in keyframes realistically, a transformation matrix of inverse kinematics and some kinds of constraints are applied. Also, to edit emotional expressions efficiently, a comic-style facial model having only eyebrows, eyes nose, and mouth is employed. Experimental results show a possibility that the editor could be used for intelligent sign-language image communications between different lan-guages.

We think that the class homepage can be solution for the problems in the cyber space or on-line community because students can practice activities in the on-line community, communicate with teachers or colleague, exchange opinions with parents and use it for learning. However, students would lose interest easily in the existing class homepage for lack of its immersion elements as compared with the commercial on-line communities. The class homepage needs to have immersion elements to reach its purpose. It is one of the solutions to use the avatars. Therefore, we studied on the influence of the avatars as the immersion of the elementary class homepage and the students cyber-self. As a result, we knew that the avatars can act enough as immersion element to achieve construction purpose of the class homepage and that use avatar helps in affirmative cyber self formation of elementary students.
