As the competition becomes more severe, the importance of brand confidence is coming to the front mainly because there has been a tendency of the customer for choosing a product or service in conjunction with the confidence. The concept of brand personality has formed as a result of various efforts for establishing a differentiated and confident brand image. The brand personality is regarded a useful mean for meeting objectives of a corporation for establishing a distinctive brand identity as well as customers for expressing their self-image. In line with the growing importance of the brand personality, researchers have attempted to measure it by various methods. However, most of researches were based on verbal and quantitative methods which take a long period of time and lots of efforts to analyze their results. Such methods also have limitations for visualizing the results. In this vein, this study aims to develop a new visible brand personality measurement system by utilizing the purpose-designed avatar. Major findings of the study are as follows: Firstly, the avatar can be an effective mean for visualizing the brand personality. As the avatar can visualize the personalities of human-beings through facial expressions, clothing, attitudes and movements, a specially designed avatar can express the brand personality. Secondly, types of the brand personality can be segregated into distinctive seven classes and such classes are used as guidelines for developing specially designed brand personality avatars. Thirdly, the purpose-designed brand personality avatar can be an effective mean for measuring the brand personality as a result of various tests for the validity. In condusion, avatar can be a more powerful tool than language for measuring the brand personality.

CVE(Collaborative Virtual Environment) is the virtually shared area where people cannot come together physically, but wish to discuss, collaborate on, or even dispute certain matters. In CVEs, in habitants are usually represented by humanoid embodiments, generally referred to as avatars. But most current graphical CVE systems fail to reflect the natural relationship between the avatar's gesture and the conversation that is taking place. More than 65% of the information exchanged during a person to person conversation is carried on the nonverbal band. Therefore, it is expected to be beneficial to provide such communication channels in CVEs in some way. To address this issue, this study proposes a scheme to represent avatar's gestures that can support the CVE users' communication. In the first level, this study classifies the non-verbal communication forms that can be applicable to avatar gesture design. In the second level, this study categorizes the body language according to the types of interaction with verbal language. And in the third level, this study examines gestures with relevant verbal expressions according to the body parts-from head to feet. One bodily gesture can be analyzed in the description of gesture representation, the meaning of gesture and the possible expressions, which can be used in gestural situation.

In this paper, we present the virtual dancing studio for distributed virtual environment. In this system, geographically distributed user shares the virtual dancing hall and interacts with each other. The participating object can be a graphical avatar or a live video stream. It allows the coexistence of graphic objects and real images in the shared virtual space. One of the main technical challenges in developing the distributed virtual environment is to handle excessive network traffic. In an effort to effectively reduce the network traffic, we propose a scheme to adjust the QoS of each object with respect to the distance from the observer in the virtual space. The server maintains the QoS vector for each client's shared space and controls the packet traffic to individual clients based on its QoS vectors. We develop a proto-type virtual dancing environment. Java based development enables the client to be platform independent. The result of experiment shows that the adoption of hierarchical QoS management significantly reduces the overall network traffic.

As a virtual identity on the virtual space, Avata is expressed in the various graphic forms such as 2D and 3D. Avata is not just combination of characters, but it also reveals the cultural Avitus of the times or the society, which often represents the discrimination according to the generation or social stratum or the unconscious choice of popular culture The modern days are absolutely influenced by the popular culture. And, it is also the case in the virtual space as well as the real world, influencing the fashion trend, cultural taste, and even the behavioral pattern of individuals. Hereupon, through an analysis of cases of using Avata character graphic, we are going to look into the technical ways of expressing Avata and the overall pop culture trend and individual life pattern and taste which are shown in the choice of outfit, necessaries, and background. And, we will also find out the kitsch characteristics in the consumption of Avata. And, we also expect that the image of Avata would be developing into a positive identity demonstrating one's existence on the virtual space, not simply a meaningless choice and combination of image in expressing and consuming Avata.

This study aims to examine the realistic self-esteem of adolescents and perception of adolescents toward avatar in an attempt to understand basic aspects of their distinctive lifestyle fundamentally relative to the cyber culture on the web, given that the adolescent which is significant in forming self-esteem period plays an important role in the psychological aspect of adolescents. As for method of research, this study analyzed the self-esteem of users, their preference for avatar, and the perception toward avatar, in order to understand their psychological and social maturity. The result of study indicated that the increased self-esteem in reality among the adolescents led to the increased preference for avatar relative to the cyber culture on the web, which in turn increased the recognition of others' avatars. Those findings suggest that adolescents tend to assign self-esteem to avatar as great as themselves. Thus, it may be important to help adolescents form their self identity from the perspective psychological maturity, so that a sound and healthy web culture can be formed depending on the formation and level of self-esteem among adolescents.

Creating controllable, responsive avatars is an important problem in computer games and virtual environments. Recently, large collections of motion capture data have been exploited for increased realism in avatar animation and control. Large motion sets have the advantage of accommodating a broad variety of natural human motion. However, when a motion set is large, the time required to identify an appropriate sequence of motions is the bottleneck for achieving interactive avatar control. In this paper, we present a novel method for training avatar behaviors from unlabelled motion data in order to animate and control avatars at minimal runtime cost. Based on machine learning technique, called Q-teaming, our training method allows the avatar to learn how to act in any given situation through trial-and-error interactions with a dynamic environment. We demonstrate the effectiveness of our approach through examples that include avatars interacting with each other and with the user.

An avatar script language consists of commands set which is used to control avatar behaviors in cyberspace. The script language should be abstract from complex low-level concepts, so that a user can write down a scenario script easily without concerning about physical motion parameters. Also, the script should be defined in a standard format and structure to allow reusing in various implementation tools. In this paper, a layered script language is proposed for avatar behavior representation and control, which consists of task-level behavior, high-level motion and primitive motion script language. The script language of each layer represents behavior elements for a scenario scripting interface, an avatar motion sequence, and geometric information of implementation environment, respectively. Therefore, a user can create a scenario script by abstract behavior interface and a script can be applied to various implementations by the proposed translating process. A presentation domain is chosen for applying the proposed script language and the implementation result shows that the script is flexibly applied in several applications.

A script language, which represents and controls avatar behaviors in a natural language style, is especially remarkable, because it can provide a fast and easy way to develop an animation scenario script. However, the studies that consider avatar behavior interactions with various virtual objects and intuitive interface techniques to design scenario script have been lack. Therefore, we proposed a context-based avatar-object behavior model and layered script language. The model defines context-based elements to solve ambiguity problems that occur in abstract behavior interface and it provides user interface to control avatar in the object-based approach. Also, the proposed avatar behavior script language consisted of a layered structure that represents domain user interface, motion sequence, and implement environment information at each level. Using the proposed methods, the user can conveniently and quickly design an avatar-object behavior scenario script.
