A vehicle driving simulator is a virtual reality device which a human being feels as if the one drives a vehicle actually. The driving simulator is used effectively for studying interaction of a driver-vehicle and developing vehicle system of a new concept. The driving simulator consists of a vehicle motion bed system, motion controller, visual and audio system, vehicle dynamic analysis system, cockpit system, and etc. In it is paper, the main procedures to develop the driving simulator are classified by five parts. First, a motion bed system and a motion controller, which can track a reference trajectory, are developed. Secondly, a performance evaluation of the motion bed system for the driving simulator is carried out using LVDTs and accelerometers. Thirdly, a washout algorithm to realize a motion of an actual vehicle in the driving simulator is developed. The algorithm changes the motion space of a vehicle into the workspace of the driving simulator. Fourthly, a visual and audio system for feeling higher realization is developed. Finally, an integration system to communicate and monitor between sub systems is developed.

Recent development in multi-channel surround is emerging in various formats to provide better stereoscopic and sound effects to consumers in recent broadcasting. The ability sound localize the sound sources in space is most considerable design factor on multi-channel surround system for human earing perception model. However, this paper propose the change of the sound localization according to the spacing of the speakers, which is not covered in the existing research focus on sound system design. Presently the sound system uses the position and number of the speakers to localize the sound. In the multi-channel surround environment, the proposed design uses the sound localization is caused by the directional characteristics of the speaker, the distance between the speakers and the distance between the listener and the speaker according to the directivity is required. The proposed design is simulated using virtual measurement with MATLAB simulation environment and performances are measured.

This paper proposes a novel computer-human interface, named invisible Messenger. It integrates face detection and tracking, and speaker array signal processing. By speaker array it is possible to form acoustic focus at the arbitrary location that is measured by the face tracking. Thus the proposed system can whisper in a person's ear as if an invisible virtual messenger were standing by the person. Not only speculative discussion, the authors have implemented a working prototype system based upon the proposed idea. This paper also describes about this prototype. In order to confirm effectiveness of the proposed idea, the authors conduct experiments using the implemented system. Experimental results demonstrate the effectivenss of the proposed idea.

We recognize analysing and quantifying an effect of light and colors on people' psychological response changing according to environmental conditions as important. Therefore, this study intends to improve efficiency in realizing emotional design that contributes to creation of helpful and pleasant interior using architecture that is able to refresh human emotion or light and colors which are important factors in interior design. For the purpose, this study analyses an effect of colors in interior space and the effect of interaction between light and color through modeling to identify types of psychological response. And it is to present a generalized conclusion through an analysis of meaning of the two effects. The ultimate goal of this study is to identify the value and possibility of actual design. This study measures response on questionnaire through representative vocabulary by abstracting based on evaluation image selected through the 1st and 2nd preparatory research and grouping similar words. In next step, images represented both by light and colors are presented as virtual space and for data input and analysis based on psychological response corresponding to each image, this study uses SPSS 11.0 statistical package program to analyse data collected. The space to be experimented is a livingroom, a center of residential area.

Objective: Research on the transformation of interaction between mobile machines and users through analysis on current gesture interface technology development trend. Background: For smooth interaction between machines and users, interface technology has evolved from "command line" to "mouse", and now "touch" and "gesture recognition" have been researched and being used. In the future, the technology is destined to evolve into "multi-modal", the fusion of the visual and auditory senses and "3D multi-modal", where three dimensional virtual world and brain waves are being used. Method: Within the development of computer interface, which follows the evolution of mobile machines, actively researching gesture interface and related technologies' trend and development will be studied comprehensively. Through investigation based on gesture based information gathering techniques, they will be separated in four categories: sensor, touch, visual, and multi-modal gesture interfaces. Each category will be researched through technology trend and existing actual examples. Through this methods, the transformation of mobile machine and human interaction will be studied. Conclusion: Gesture based interface technology realizes intelligent communication skill on interaction relation ship between existing static machines and users. Thus, this technology is important element technology that will transform the interaction between a man and a machine more dynamic. Application: The result of this study may help to develop gesture interface design currently in use.

The purpose of this study was to expand the expression of Fashion Illustration using Lenticular imaging process. In the 2-dimensional pictures, Lenticular imaging process can be effective to make multiple, virtual and variable images, which are assumed the main characteristics of modern Fashion Illustration. For this study, the main characteristics of digital based fashion trend and Fashion Illustration were analyzed. The main characteristics of digital based fashion were 'Interaction, Variableness, Virtuality, Multiples and Hyper-text' which were related with Simulacre thinking. The main characteristics of expression in Fashion Illustration were 'Virtuality and Multiples'. The image of 'Variableness' was an important factor in digital based fashion, but it was restricted within Fashion Illustration because of the 2-dimensional picture. Therefore, the Lenticular imaging process was proposed as an effective method to expand 2-dimensional limit, giving an effect of 'Variableness' in Fashion Illustration. Based on this study, 5 illustration works were proposed. The Lenticular imaging process was applied in making the images of 'Virtuality, Multiples and Variableness' in 5 works. The result of this study can be a basic material to understand the characteristics of modern Fashion Illustration as a meaningful sub-culture, and diverse expressions corresponding with the phases of the times.

본 논문에서는 $CAVEW^{TM}-like$ 시스템과 같은 대형 디스플레이 기반의 몰입형 시뮬레이션 환경에 필요한 인터랙션 기법을 제안한다. 축소 모형(miniature) 인터랙션은 원거리에 있는 객체를 쉽게 선택하거나 조작하기 위하여 가상 세계 전체를 축소하여 사용자 근처에 디스플레이하고 이를 조작함으로써 대상 객체와 상호작용 할 수 있도록 해준다. 또한, 조감도(bird's eye view)로 표현되는 지도상에 사용자 위치를 표시하여 가상 세계 탐색시 이동 경로를 쉽게 파악할 수 있도록 하였다. 축소 모형은 투명 패널 인터페이스를 통하여 보여지며 사용자는 이를 이용하여 택타일 피드백(tactile feedback)을 제공 받을 수 있다. 그리드(grid)를 이용한 비주얼 가이더는 가상 세계 내에 그리드를 디스플레이하여 대상 객체와 사용자간의 위치 관계를 쉽게 파악할 수 있도록 해준다. 일반적으로 대형 디스플레이 환경에서의 인터랙션은 정확한 깊이 인식이 어렵기 때문에 인터랙션 시사용자의 불필요한 행위를 유발하게 된다. 본 논문에서 제안하는 기법은 이 같은 문제점을_개선하여 객체 조작 시 느껴지는 피로감을 최소화 시킬 수 있으며 다양한 몰입 및 상황 기반 시뮬레이션 어플리케이션에 적용되어 활성화 될 수 있다.

가상현실을 이용한 사람의 빠른 움직임을 추출하여 파형으로 나타내는 동작곡선이나 자연계에서 실제로 관측되는 대기 전기변동량과 같은 전자계 신호의 시간 변동량은 매우 복잡하다. 이러한 신호의 관측파형에 대하여 변곡점과 같은 신호의 특징을 정확히 결정하는 것이 중요하다. 잡음이 신호에 중첩될 때 종래의 방법으로는 변곡점의 검출이 어렵다. 본 논문에서는 신호에 잡음이 첨가될 때 웨이브릿 임계치 잡음제거와 정규형 자연관측필터를 적용하여 정확한 변곡점 추출이 가능함을 보인다.

본 논문에서 우리는 감정 에이전트를 이용한 자동 이야기 생성 시스템을 제안한다. 제안한 시스템에서 감정 에이전트는 배우로서, 이야기 생성 시스템은 이러한 배우 및 감독 등을 이용하여 목표 지향적으로 이야기를 만들어 낸다. 자동 이야기 생성 시스템에서, 목표는 몇 가지의 상세한 계획으로 나뉘고 목표를 이루기 위한 계획을 수행함으로 이야기를 만들어 낸다. 이러한 이야기 생성 시스템은 감정 에이전트를 사용하기 때문에, 마치 감정을 소유한 인간이 연기를 하는 것처럼 효율적으로 이야기를 생성한다.
