The success of a three-dimensional blockbuster movie, AVARTA, brought an public attention on the expansion of three-dimensional computer applications, and it allows experts predict further hardware technology developments to support the such applications. Futhermore, an internet based infra structure and three-dimensional structure, third generation network community, advanced computer networks have influenced advancement in computer technology within the 3D game industry and the spread of 2D computer animation technologies. This advancement of computer technologies allow the industry to overcome a limitation of generating cultural design contexts existed within 2D network community. However, despite of the expansion of 2D and 3D computer technologies, a limitation of analysing designers' intentions on morphology of digital contents and user interface still exists. Therefore, the purpose of this study is to analyze (1) present conditions of the 3D industry and (2) protocols of designers' cognitive design processes based on their design communication, contents, and tools. Analysis was conducted based on literature reviews and case precedent analyses. For the analysis, a 2D Avarta sketch character was designed and then applied into a 3D game system. Observations how designers solve cultural problem within the structure via Avarta were conducted. Outcomes were then coded for further analysis.

Many People are collecting and managing variable information(Image, Graphic, Animation, Text, music files etc.) about personal interests and holding them in common. Most users are using Microsoft Explorer to make a folder and classify many files. but It's difficult to understand the relation of the data instinctively. To resolve this problem, we adopt information visualization method (especially tree-graph control interface). We suggest an interface that all user can drawing a Graph easily and rapidly. So user can see the relations of their data instinctively and control the relation directly with our sketch-based interface.

In this paper, we propose user-centric immersible and interactive electronic book based on the interface of tabletop display. Electronic book is usually used for users that want to read the text book with multimedia contents like video, audio, animation and etc. It is based on tabletop display platform then the conventional input device like keyboard and mouse is not essentially needed. Users can interact with the contents based on the gestures defined for the interface of tabletop display using hand finger touches then it gives superior and effective interface for users to use the electronic book interestingly. This interface supports multiple users then it gives more diverse effects on the conventional electronic contents just made for one user. In this paper our method gives new way for the conventional electronics book and it can define the user-centric gestures and help users to interact with the book easily. We expect our method can be utilized for many edutainment contents.

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.

'Jump' control is one of several game controls using mainly in 2D game, and 'Jump' control is also very important in 3D game that has been developed steadily due to the advance of programing technology. 3D MMORPG among some kinds of 3D games is the most popular as on-line game in domestic game market these days. This study will give domestic game developers ideas and solutions through analyzing and testing problems caused by applying 'Jump' control technique as control interface of 3D MMORPG game.

Recently, processing burden of CPU is growing because of graphical user interface according to enhance the performance of mobile devices and various graphical effects and creation of contents with 3D graphical effect or Flash animation. Therefore, the GPU are introduced to mobile device for support to variety contents. In this paper, OpenVG accelerator was implemented based on multi-core GP-GPU. OpenVG accelerator is verified using the sample image provided by Khronos group, and overall function is processed by only instruction set without dedicate hardware. The performance of processing the Tiger Image was 2 frames/sec.

Robot design serves as the crucial link between a human and a robot, the cutting edge technology. The importance of the robot design certainly will be more emphasized when the consumer robot market matures. For coexistence of a human and a robot, human friendly interface design and robot design with consideration of human interaction need to be developed. This research extracts series of functions in need which are consisted of series of case studies for planning and designing of 'A Shopping Support Robot'. The plan for the robot is carried out according to HRI aspects of Design and the designing process fellows. Definite results are derived by the application of series of HRI aspects such as gestures, expressions and sound. In order to verify the effectiveness of application of HRI aspects, this research suggests unified interaction that is consisted of motion-capture, animation, brain waves and sound between a human and a robot.

This paper presents a windows application for voltage sag analysis and effective data visualization. The developed Voltage Sag Analysis Tool (VSAT) was designed by using the Object-Oriented Programming (OOP) concept and C++ programming language. The VSAT provides basic functions for voltage sag analysis such as power flow analysis, short circuit analysis and stochastic analysis. In particular, the VSAT provides effective data visualization through computer graphics and animation. Analysis results are expressed realistically and intuitively on geographical display. The Graphic User Interface (GUI) of VSAT was designed specifically for voltage sag analysis. In this paper, the development and implementation of VSAT is presented. In order to demonstrate the capabilities of VSAT, it is used to analyze the Jeju Island power system in South Korea.

애니메이션은 이미지나 텍스트와 같이 정적인 방식에 비해 효과적인 정보전달방식이다. 이는 간단한 표현이라도 동적인 움직임으로 구성될 때 더욱 흥미를 유발하며 높은 전달력을 가지게 되기 때문이다. 그러나 현재 웹 환경에서의 애니메이션 제작 방식은 전문적인 제작 도구를 사용하는데 국한되어 있어, 일반적인 사용자들의 참여를 통한 활용에는 적합하지 못한 방식이다. 본 논문은 사용자의 의도를 쉽고 직관적으로 반영할 수 있는 애니메이션 생성 인터페이스 기법을 제안하며, 실제 웹 환경에서 정보의 공유와 의사전달에 있어 직관적이고 쉬운 방식으로 애니메이션을 활용하는 방안을 제시한다.

다양한 스타일의 인간 동작을 쉽고 빠르게 생성하는 일은 캐릭터 애니메이션에서 매우 중요한 문제이다 실제로 이러한 애니메이션을 만드는데 있어서 가장 고품질의 결과를 얻을 수 있는 방법은, 전문 애니메이터가 3차원 애니메이션 제작 도구를 사용하여 직접 만드는 것이다. 하지만 일반 사용자가 이와 비슷한 애니메이션을 만드는 것은 어려운 일이다. 이 논문에서는 누구나 쉽게, 그리고 일정 품질 이상으로 3차원 캐릭터 애니메이션을 제작할 수 있는 시스템을 제안한다. 이를 위해서 스케치기반 인터페이스와 모션 데이터베이스를 이용한다. 스케치기반 인터페이스는 일반 사용자가 어렵게 느낄 수 있는, 키 프레임을 쉽고 빠르게 지정할 수 있도록 도와준다. 모션 데이터베이스는 이러한 키 프레임을 설정을 돕고, 애니메이션 제작에 필요한 키 프레임 수를 줄인다. 이 방법으로 누구나 원하는 애니메이션을 쉽고 빠르게 생성할 수 있다.
