공공 디자인에서 공공성의 실현 여부를 판단하는 데는 해당 디자인의 수행 과정과 방향성 등 다양한 측면이 고려 돼야한다. 공공 디자인이란 공공성을 갖춘 디자인이다. 그럼에도 무엇보다도 사용자에게 미적관심을 유발시키는 것이 우선이다. 한편, 디자인의 편의성은 심미성을 높이는데 기여하기도 한다. 연구자가 시도한 융복합적인 인터랙션을 적용한 공공디자인은 공공장소에서 사적 영역의 보호와 같은 공공성을 체험토록 기획하였다. 꽃술을 모티브로 하여 심미성에 바탕을 두면서 기능적으로는 뉴미디어의 인터랙션을 활용한 이 공용 벤치 디자인 제안은 사용자의 미적 반응에서 시작하여 편의성과 쾌적함 나아가 사용자가 체험하는 공공성의 경험이 공공 디자인의 의미와 가치판단을 가능하게 하는 요소임을 제시한다.

The development of computer integrated systems for structural design requires models to describe and organize information and activities involved in design. An entity-based integrated design model involves a number of product and process entities. Product entities and process entities describe design information and design activities, respectively. One type of relationships among entities is interaction relationships, which describe interdependencies among design information. The interaction relationships can be represented as constraints. Types of constraints include demand constraints, dependency constraints, and interaction constraints. The concepts of representing and processing demand constraints in an entity-based integrated design model are presented.

본 연구는 웹기반 교육 체제에서의 학습자가 교육목표를 달성하는 데 있어 중요한 역할을 하는 인터랙션을 컨텐츠적 측면과 연관지어 분석해 봄으로서 궁극적으로 학습자에게 보다 만족스러운 인터랙션을 제공하는 웹기반 교육 사이트의 설계 전략을 모색하는 데 목적이 있다. 우선 문헌연구를 통해 웹기반 교육과 인터랙션에의 개념 및 의의를 고찰하여 웹기반 교육 설계원리들이 실제 웹기반 교육사이트에서 어떻게 이루어지고 있는지 상호작용 측면에서 분석하여 기존 수업의 어떤 요소를 충분히 활용하고 어떤 요소를 보강하여야 할지 알아보았다. 그 결과 웹기반 교육사이트들은 사회적측면의 인터랙션보다는 시스템측면의 인터랙션으로 '정보'를 전달하기 위한 커뮤니케이션 디자인에 기반한 컬러, 텍스트, 이미지 등 시스템 '각각의 디자인 요소'들과의 인터랙션을 더 활용하고 있는 것으로 나타났다.

This study has a purpose mainly to analyze the team interaction change by the duration of time in the Capstone-Design activities according to MBTI Modes. Study objects are four students of Mechanical Engineering at School of Engineering in C University located in Daejeon, and the team interaction change was analyzed through IPA (Interaction Process Analysis) method. From the result, first, ESTP showed the change of increase in interaction by the time duration of initial, mid, late periods in 'social-emotional area: positive' and 'task area: question', and the change of decrease by the same time duration of periods in 'task area: solution'. Also, there was no change in 'social-emotional area: negative' because there was no interaction. Second, ESFJ showed the change of decrease in interaction by the time duration of initial, mid, late periods in 'social-emotional area: positive' and 'task area: question', and the change of increase by the same time duration of periods in 'task area: solution' and 'social-emotional area: negative'. Third, ISTJ showed the change of decrease in interaction by the time duration of initial, mid, late periods in 'social-emotional area: positive', 'task area: question' and 'social-emotional area: negative', and the change of increase by the same time duration of periods in 'task area: solution'. Fourth, ENFP showed the change of decrease by the time duration of initial, mid, late periods in 'social-emotional area: positive', 'task area: solution' and 'social-emotional area: negative', and the change of increase by the same time duration of periods in 'task area: question'.

Various interaction techniques have been studied for providing the feeling of touch and improve immersion in augmented reality (AR) environments. Tangible AR interaction exploiting two types (product-type and pointer-type) of simple objects has earned great interest for cost-effective design evaluation of digital handheld products. When the sizes of markers attached to the objects are kept big to obtain better marker recognition, the pointer-type object frequently and significantly occludes the product-type object, which deteriorates natural visualization and level of immersion in an AR environment. In this paper, in order to overcome such problems, we propose tangible AR interaction using fingertip touch combined with small-sized markers. The proposed approach facilitates the use of convex polygons to recover the boundaries of AR markers which are partially occluded. It also properly enlarges the pattern area of each AR marker to reduce the sizes of AR markers without sacrificing the quality of marker detection. We empirically verified the quality of the proposed approach, and applied it in the process of design evaluation of digital products. From experimental results, we found that the approach is comparably accurate enough to be applied to the design evaluation process and tangible enough to provide a pseudo feeling of manipulating virtual products with human hands.

'Sustainable Development' has become one of the most important concepts of the 21st century, and efforts are being made to actively apply this conception in various fields of social studies. Sustainability can be discussed in terms of economy, environment and society. In the case of social sustainability, a key motivation is the weakened bond within communities that is an unfortunate characteristic of modern society. The core of social sustainability is therefore in promoting 'social interaction and communication' through constructing communities and physical environments that support them. This study is based on the understanding that areal enlargement of physical environment doesn't guarantee the vitality of created community spaces. The purpose of this study is to deduce the design objectives and strategies of communal spaces in apartment complexes for social interaction and communication. Social interaction and communication can be divided into two aspects: between a complex and the local society, and within the complex itself. Nine design objectives are deduced from sixteen research reports published by public research institutions after 2000 and several design strategies are found through architectural analyses of influential examples based on 5 fundamental values of communal space planning.

This paper presents a novel approach to design evaluation of portable consumer electronic (PCE) products using augmented reality (AR) based tangible interaction and functional behavior simulation. In the approach, the realistic visualization is acquired by overlaying the rendered image of a PCE product on the real world environment in real-time using computer vision based augmented reality. For tangible user interaction in an AR environment, the user creates input events by touching specified regions of the product-type tangible object with the pointer-type tangible object. For functional behavior simulation, we adopt state transition methodology to capture the functional behavior of the product into a markup language-based information model, and build a finite state machine (FSM) to controls the transition between states of the product based on the information model. The FSM is combined with AR-based tangible objects whose operation in the AR environment facilitates the realistic visualization and functional simulation of the product, and thus realizes faster product design and development. Based on the proposed approach, a product design evaluation system has been developed and applied for the design evaluation of various PCE products with highly encouraging feedbacks from users.

For a $2 \times 2$ factorial design without the restriction of a linear model or without regard to error terms having homoscedasticity, under the null hypothesis of no interaction we can have the rank transformed F statistic for interaction converge in distribution to a chi-squared random variable with one degree of random if and only if there is only main effect.

Many studies have indicated that most of a product's cost is fixed early in its lift cycle, before the original design cycle is complete. This implies that we should consider various aspects of product lift cycle at the design stage. This means the need of collaboration in design stage. Because the Internet provides instant access to a wealth of design information, the Internet is used by the collaborative design team members as a medium to share data, information and knowledge, and in some cases for product data management and project management by integrating the Web with appropriate technologies. This paper presents a real-time collaborative design system for powerful interaction performance, based on the Internet and Web technologies. Using The system use the client/server architecture and the purpose of the system is to provide a method that enables real-time view, review and modification of the 3D model through the Internet.
