Today, mobile technology is developing very fast and people use internet through mobile phones. Using mobile phones, people use games, email, avatar and other services. We designed client/server modules in order to join email and avatar together. First two major server modules were designed, one of them is DB management module for avatar user information and the other is email management module. One the client side, we designed avatar image animation module and a module for showing the email contents. The purpose of the design is to reduce the performance overhead on the client side as mobile phones cannot be used as a high performance device. We propose and implement a new avatar based service using the SK-VM environment, that is different from the current avatar services.

In this paper, video avatar, made from live video streams captured from a real participant, was used to represent a virtual participant. By using video avatar to represent participants, the sense of reality for participants can be increased, but the correct registration is also an important issue. We configured the real and virtual cameras to have the same characteristics in order to register the video avatar. Comparing real and synthetic images, which is possible because of the similarities between real and virtual cameras, resolved registration between video avatar captured from real environment and virtual environment. The degree of incorrect registration was represented as energy, and the energy was then minimized to produce seamless registration. Experimental results show the proposed method can be used effectively for registration of video avatar.

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.

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.

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.

As a means of overcoming the linguistic barrier in the Internet cyberspace, recently a couple of studies on intelligent avatar communications between avatars of different languages such as Japanese-Korean have been performed. In this paper we measure the generation time of facial expressions on different avatar models in order to consider avatar models to be available in real-time system. We also provide a short overview about DTD (Document Type Definition) to deliver the facial and gesture animation parameters between avatars as an XML data.

These days, mobile technology is developing very fast. It has increased the usage of the Internet by mobile phones. Nowadays the avatar and game contents services are most popular in mobile phones using the Internet. In this paper, we propose a Client/Server system to combine the animation avatar and e-mail services on SK-VM which are different from simple avatar services. The server which consists of DB (database) module and mail management module is designed in order to manage the information about avatar and the user. The client is designed so as to show the email contents and avatar animation on the mobile phone. This model is intended to reduce the performance overhead on the client as much as possible. We expect that this module would be useful in the mobile phones with limited resources, although the technology is being developed very rapidly.

In spite of recent increase in the use of avatar in Web and Virtual Reality, there has not been a service that allows users to control directly the avatar behaviors. In addition, the conventional behavior control languages required a lot of complicated information for controlling the avatar motions. Moreover, in order to apply written languages to a different task domain, it was necessary to modify or rewrite the languages. In this paper, we define Task-Level Behavior Description Language and Motion Representation Language for more simple control of the avatar behavior. The first thing allows describing the avatar behaviors in each task domain, and The second thing enables writing detailed data for motion control. And in this paper, we developed an interpreter which can automatically change the Behavior Description Language to the Motion Representation Language. So this system allow users control the avatar behavior simply with only use the Behavior Description Language. The system was applied to shopping mall and the Task-level Behavior Description Language was compared with conventional languages to see how it was more effective in behavior description.
