자동차는 이제 단순한 운송 수단이 아닌 생활의 한 공간으로써 인식되어야 하며, 자동차 내부의 각종 편의장치 또한 사용자 중심적 견해에서 해석되어야 한다. 자동차 내부에는 운전에 관계된 조작장치 이외에도 오디오, 공기조절기와 같은 각종 편의장치들이 존재하며, 일반적 상황이 아닌 운전 작업 줌에 조작이 행해진다는 정에서 특히 사용자에 대한 배려가 이루어져야 한다고 볼 수 있다. 본 연구의 목적은 자동차 실내를 대상으로 하여 그 사용환경 내에서 사용자의 행위와 사용환경내 오브젝트와의 인터랙션에 대한 정보를 수집하고, 수집된 정보를 구조화하여 분석함으로써, 사용자 중심 디자인에 반영할 수 있는 정보모텔을 작성하는데 있다.

제품을 사용한다는 것은 어떤 목적을 달성하기 위한 제품과 사용자 사이의 입력과 출력과정으로 해석할 수 있다. 이런 측면에서 제품과 사용자와의 관계를 고찰해 볼 때 최근에 부쩍 그 수가 늘어난 지능형 제품들은 이전의 제품들이 물리적이고 신체적인 자원의 투입과 이에 따른 기계적인 제품반응에 의해 사용자와 직접적이고 단순한 제어-피제어의 관계를 가졌던 것과는 달리 지적인 자원의 투입과 함께 제품으로부터 지적인 결과물을 출력받아 사용자가 이를 다시 해석해야하는 간접적이면서도 쌍방향적인 교류관계를 가진다.(중략)

이 논문은 웹기반 소프트웨어를 테스트하기 위한 오러클을 생성하는 방법을 제안하고 설명한다. 웹 페이지를 구성하는 응용 컴포넌트들의 구조를 파악하고 각 페이지를 구동시키는 액션들을 찾아내어 상태기반의 테스트 데이터를 찾아내는 방법이다. 테스트 스크립트를 작성하기 위하여 partial-W 방법을 도입하였으며 이를 이용하여 테스트 케이스의 값을 선택할 수 있다. 테스트 슈트는 언어 독립적이며 실행가능하다. 웹 응용의 특징인 동적인 인터렉션을 유한 상태기계(Finite State Machine)로 표현하고 각 상태를 변화시키는 웹 페이지의 사용자 입격을 결합하여 테스트 오러클을 생성한다.

Applying maintenance simulation using virtual mockup in product design phase enables maintainability test before prototyping physical products, and it is expected to reduce product development costs. The simulation results can be reused as contents of service manuals and RAM (Reliability, Availability, Maintainability) analysis data. Maintenance simulation should provide realistic representation of physical property of virtual product, assembly relation between parts and manipulation process to verify feasibility of product design. The simulation system should be extended to collaborative virtual environment to perform collaborative maintenance procedures. In this paper, the three layered system architecture and the physics based collaborative interaction technique are proposed to extend current maintenance simulation into collaborative virtual environment. The proposed system was implemented as ViMMS (Virtual Mockup Maintenance Simulation system), and compared with case study results of VADE (Virtual Assembly Design Environment). As a result, the ViMMS encompassed broader range of maintenance tasks by using physics based collaborative interaction technique.

This study focused on user centered design methodology on mobile service design, Especially we designed business supporting service for sale persons with heavy mobile uses in their works. We used contextual inquiry interview to understand user's work context and mobile usage. The findings are applied to the service concept, And information architecture, interaction design, GUI design is followed. As a result of design research, Post widget service is designed for instant information organization and functional relationship. And Memory box widget service is designed for business network management and contextual findability. Those services are developed for widget design on touch based phone platform.

Edutainment is the one of important factors to study interactive TV for children, and it is a big portion in kid's marketing and education market as well. The aim of this study is to design interactive TV for children to maximize edutainment effects by researching children's behaviors. The analysis of children's behaviors with educational effects should be focused to apply designing user experience to propose new ideas of interactive TV. Through observing children's behaviors and interaction with other media, such as books, CD players, digital camera, and so on, TV can be reanalyzed as reliable media, which is creative interactive TV for children with proposals of user experience structure and interaction solution. TV has been changed from analog TV to IPTV and it will be different with network and interactive solution.

The information technology is quickly changing the paradigm of the overall society. This change has influenced the art field and exceeded the limit of prior art characteristics and methods opening up a new world of art pieces starting among the young artists based on digital art technology. Especially the internet art of the computer technology made the communication of the artist and the viewer to communicate in a bilateral manner different from one way feeding of the past and made it possible for the viewers to choose their involvement in the act of seeing the work changing the reaction into a fluid concept. This thesis is about using the digital media in the net art communication to figure out the fluid interaction by approaching the digital media concept and by analyzing the characteristics of net art communication means and thus take a overall look at the artist related web sites and see the net art as a new communication means.

The purpose of this study was to test a large screen and rear-projected virtual reality (VR) interface in color choice for environmental design. The study piloted a single three-dimensional model of a bedroom including furniture in different color combinations. Using a mouse with an $8'{\times}6'$ rear-projector screen, participants could move 360 degree motion in each room. The study used 34 college students who viewed and interacted with virtual rooms projected on a large screen, then filled out a survey. This study aimed to understand the interaction between the users and the VR interface through measurable dimensions of the interaction: interest and user perceptions of presence and emotion. Specifically, the study focused on spatial presence, topic involvement, and enjoyment. Findings should inform design researchers how empirical evidence involving environmental effects can be obtained using a VR interface and how users experience the interaction with the interface.

In this paper, we propose an HMD-AR interaction system that combines optical camera communication to provide location-based service for tourists in Jeonju Hanok Village. The proposed system receives optical camera communication data from Light infrastructure existing in Jeonju Hanok Village and provides service through ID information along with its own location information. We researched optical camera communication technology and smart device based HMD-AR system and constructed the actual HMD-AR system and tested it. The proposed system is expected that it will be applied to various tourist attractions by utilizing the proposed system in the future, and it is expected to be used as a valuable feedback for smart device based HMD-AR.
