본 연구의 목적은 비디오/오디오 프로토콜 분석 방식을 이용해서 텍스타일 디자인 프로세스 중 모티브 개발 단계에서 디지털 나염(DTP : Digital Textile Printing) 전용 캐드(CAD)와 같은 디자인 저작도구를 설계할 때 어떤 요소에 중점을 두고 개발 할 것인지에 대한 향상된 지침을 마련하는데 있다. 텍스타일 디자인 프로세스에 대한 프로토콜 분석을 위해 선행 연구를 고찰하여 디자인 행동 범주의 틀을 하향식(top-down)방식으로 설정하고 실제 행동 프로토콜 (action protocol) 분석을 통해 상향식(bottom-up)방식으로 세부 디자인 행동을 도출하였다. 텍스타일 디자인은 선행연구의 건축디자인과는 다른 특징을 지니기 때문에 프로토콜 분석에서도 새로운 디자인 행동 범주(action category)가 필요하게 되었다. 이를 위하여 모델 휴먼 프로세서(Model Human Processor)이론을 근거로 디자인 행동을 모터 행동(motor action), 지각 행동(perceptual action), 인지 행동(cognitive action)의 세 가지 범주[4]로 나누었으며 텍스타일 디자인 프로세스에 적합한 코딩 스킴(coding scheme)을 개발하였다. 본 연구에서는 이 새로운 코딩 스킴을 토대로 디자인 저작도구에 대한 디자이너의 인지적 모형(Cognitive Model)을 개발하였다. 이렇게 개발된 디자이너의 인지적 모형은 디지털 나염을 기반으로 하는 모티브 개발 단계에서 스케치와 렌더링에 대한 디자인 저작 도구의 향상된 설계지침 뿐만 아니라 방향도 시사하였다.

This study was an exploratory approach to the cognitive model of textile designers on the stage of motif development in textile design process. Prior to the main research, several previous studies adopting methods of video/audio protocol analysis were reviewed. On the basis of the review, the categories of design action were derived as an analysis frame by application of top-down access method, meanwhile the sub-groups of each category of design action were identified through a bottom-up access method. To summarize the research result, total three categories of textile design action appeared based on the theory of ‘Human processor’ model : ‘motor action’, ‘perceptual action’ and 'cognitive action'. In next, a new coding scheme suitably explaining these three categories of fertile design action was developed. Finally, a cognitive model of textile designer on the stage of motif development, employing the new coding scheme, was suggested in this study.

The researchers of this study closely looked into the methods for cognitive-scientific approach to problems of marine design at a time when the overall values of marine cultures are acknowledged in full scale. To that end, the researchers analyzed the problems and problem-solving process for the initial approach to marine design. At the same time, the researchers made the matrix of the design-developmental directions by cognitive scientific approach. After selecting the subjects, the researchers collected verbal protocol and behavior protocol which were shown in the process of a designer's thinking. This was for the sake of protocol analysis which is the representative research technique of cognitive science. Based on the collected data, the researchers empirically analyzed the behavior patterns shown in the marine design process so as to develop the design behavior-graph pattern of designers in an objective and systematic way. The behavior graph was helpful for looking into the initial developmental directions of design and for predicting cognitive structure of designers. The researchers hope that this study will become a fundamental material for predicting cognitive directions of designer for planning and designing the marine design.

In the "digitalized" world of new media, visual designer are increasingly enlarging their roles in desighing interaction products. However, the concepts and their methods of the interaction design have not been well established in the design community yet. The reason is attributed to the fact that designing interaction products requires two way communication between the products and final users. whereas traditional graphic design counts only on one way communication. This study emphasizes GUI design should aim at improving the usability of products which helps users quickly learn about the products and easily use them. The usability of GUI design significantly improved by securing logical rationality helps designers communicate and collaborate with program engineers and other product developers. To explain how designers can effectively communicate with program engineers and other product participants in the design process, a model of design collaboration is provided in this study. Based on the model, the study deals with the principles and methods of visual interaction, the formulation of specification system, testing design usability, and design evaluation. The study concludes that GUI designers must ensure logical rationality and the cognitive approach of visual language. Because it improves the usability of products. It also becomes an objective tool for communicating and collaborationg with engineers and the other participants in the design process.

현대는 자동차 제조업체나 차종이 매우 다양하다. 따라서 이들은 보다 고객들이 좋아하고 만족할 만한 자동차를 제조하려고 노력하는 실정이다. 하지만 현재 우리 나라에서는 자동차와 같은 인간-기계 시스템의 설계 요소들의 인터페이스 구축이 디자이너의 이상적 설계(good design)와 제품 개발자의 공학적 기능 기술에만 상당 부분 의존하고 있다. 따라서 이러한 자동차 내부 인터페이스의 설계에 있어서 인간 의 정신적, 육체적 능력을 고려한 HMI설계에 대해서는 상대적으로 등한시하고 있는 실정이다. 이에 기계의 사용성이나 인간의 인지 능력, 그리고 시스템의 성능을 고려한 인간-기계-시스템 인지 모형 개발 및 사용자 중심의 인터페이스 구축이 시급하다고 여겨진다. 본 연구에서는 동작 분석을 통한 운전 Performance를 설명하고 이에 걸리는 시간을 예측할 수 있는 모델에 대하여 연구하였다. 본 연구결과, 운전자의 Object조작에 대한 손의 움직임은 크게 세가지로 나눌 수 있었으며, 이를 바탕으로 하여, 시각과 손의 조합에 의한 모델을 제시하였다.

This study is about what process and methodology could make UI designer be able to achieve the interface which considers user's mental model through implementing corporate line-up model, when people design an interface between product of multi-function printer and user. The most important concern of UI designers who are dealing with an interface between product and user is how they can make product system image match user's mental model so that users can utilize products without any confusion and discomfort. If concept model which designers bring up and mental model which users expect and recognize could be of one accord, then users can feel ease of use toward products. The understanding and observation for user behavior and use pattern is prerequisite to develop user-centered interface between product and user. However, UI designers do design interface from their own perspective and assumption in many business areas, and users do not react as designers assumed and intended in many cases or examples. This study is to find inappropriate system images against users' mental model on basic function of multi-function printer, and the relationship of system image and user's mental model is diagramed to build up a hypothesis. The hypothesis from this study is validated through evaluation of domestic and international users. In addition, two suggestions to improve usability problems revealed from user test are proposed. The optimal solution is designed based on the result of user evaluation and consideration of many user environments, and then it is implemented to line-up product. In conclusion, this study considers how UI designers can create system image which is close to user's mental model.

The issues of generation, delivery, and processing of information which have been treated importantly in information design field have evolved along with the evolution of the humankind. In the modern society, the vast amount of, complex, and artificial forms of information such as big-data is accounted for the majority and claims of interest focusing on how to effectively design those kinds of information are being increased. This study explored the visualization methods applied with the natural objects as motives as one of the ways for users to easily get their perception and cognition to the information. Nature has long influenced on the human figural activities. The natural objects take the optimum visual shapes and provide the diverse inspiration and emotion to the designers in the various design fields such as product design, architecture design, and so on. Through the literature studies, we suggested the compositional principles of natural objects and the principles for observing and analysing natural objects as a principle to use the natural objects for information design domain. We, also, suggested the information design approach model which is inspired the natural objects by linking those two kinds of principles to the information design's visual realization factors and explored the possibilities of utilizing of the approach model by the case studies.

This paper presents an intuitive 3D modeling interlace based on a field study and prototype development. The process and tools of modeling were observed in workshops of professional design model making, day modeling, wood caning and glass crafting. The Spray Modeling interlace was developed from the observational analysis of the field study. It is a 3D modeling interface which combines particle spraying and day modeling in Virtual or Augmented Reality space. Virtual volume particles are sprayed on frames in Augmented Reality space as day modeling. It adopts a real air spay gun as a tangible interface device which provides coherent sound and air-force feedback. The prototype development and a user study showed that the interface supports new patterns of form development and expression. Control interfaces and requirements of auxiliary devices were found to be improved. This study examines the potential of the new interlace for designers working in 3D virtual and augmented reality. The new spraying interface is also expected to be used as an alternative interface in 3D computer workspace, games, education software and media art.
