"사용자 중심의 디자인(User-Centered Design)" 은 좋은 사용성을 가진 제품을 만들기 위한 사용되는 보편적인 접근방법중의 하나이다. 그러나 투자대비 최대의 가치 창조라는 경제성 원리와 개발 기간의 제약을 고려하면 개발 중 사용성 평가를 통해 발견된 문제들을 모두 제품에 반영하는 것은 거의 불가능 하다고 볼 수 있다. 그러므로 발견된 문제들에 대한 우선 순위를 정의한 후 가장 중요한 문제점에 대해 먼저 개선하는 전략이 필요하다. 기존의 사용성 문제에 대한 우선 순위는 주로 문제 자체의 심각도를 고려하여 결정되었다. 그러나 사용자가 인식하는 사용성(Perceived Usability)를 높이기 위해서는 사용자가 중요하게 생각하는 효용을 우선적으로 제품에 반영하는 것이 필수적이다. 본 연구에서는 카노의 사용자 만족 모델을 활용한 사용자 효용과 사용성 문제들의 잠재가치를 고려한 사용성 문제 분류를 기구 사용성 평가 가이드라인의 제작에 적용하였다. 제안된 분류에 의해 디자인 가이드라인을 1) 반드시 만족 시켜야하는 제품 사용성 기준, 2) 경쟁사 대비 우위를 유지하기 위한 비교평가 기준으로 나누어 정의함으로써 단일 제품의 절대적 평가가 아닌 경쟁사 제품과의 비교 평가를 통한 개선 방향의 제시에 Kano 모델을 기반으로 정의된 사용성 문제들의 효용가치분류가 효과적이라는 것을 본 연구를 통해 보이고자 한다.

최근 다양한 디지털 컨텐츠를 온라인의 서버와 오프라인의 개인 컴퓨터 혹은 소형 정보기기에서 공유하여 사용이 가능하도록 도와주는 시스템과 서비스들이 출현하고 있다. 이와 같은 시스템은 사용자가 언제, 어느 곳에 있더라도 원하는 디지털 컨텐츠에 접근할 수 있도록 도와준다는 장점을 갖고 있으며, 또한 해당 디지털 컨텐츠의 저작권을 보호할 수 있다는 부가적인 이점을 제공한다. 그러나 이들 시스템은 도입 초기에 대부분의 개발자들이 저지르기 쉬운 기능 중심적 사고에 치우친 시스템인 경우가 많다. 이들 기능 중심적인 시스템은 사용자가 해당 시스템을 어떻게 인지할 것인지에 대한 이해가 부족한 한계를 갖고 있으며, 이는 결국 시스템의 사용 편의성에 영향을 미칠 수 있다. 본 연구에서는 디지털 컨텐츠를 온라인과 오프라인에서 공유하여 사용할 수 있는 시스템의 구조적 메타포로 공간을 선택하였다. 사용자의 시스템 환경으로서 온라인과 오프라인, 그리고 사용자가 디지털 컨텐츠를 이용하여 수행하는 과업으로서 관리/저장과 사용으로 시스템의 구조를 구분하였으며, 이상의 구분에 따라 공간의 메타포를 이용하여 시스템을 디자인하였다. 이와 같이 구분한 시스템의 공간에 따라 사용자가 시스템에 대하여 갖는 관여도와 동기를 측정하였으며, 관여도의 수준과 동기의 차원에 따라 사용 편의성을 높일 수 있는 디자인 요소로서 시스템을 구현하고 있는 색상들 사이의 대비 수준과 색상의 색조 차원을 규명하고자 한다.

With the increase of the number of Internet users, various methodologies have been proposed for the effective design of web page. However, the prior methodologies have focused only on the functional aspect of web page while ignoring the emotional aspects of web pages. This paper focuses on the emotional design of home pages and aims to provide a methodology to design a web page suitable for goal emotions. In order to achieve the main purpose, we have conducted three related studies. First, we have identified basic emotional dimensions representing various feeling users have from web pages as a pool of emotional adjectives. Second, we have identified key design elements related to the emotion by observing the design process of expert designers. Third, we examined the causal relation between the perceived emotion and designed elements. The results indicate that some design elements are more effective to produce certain feeling than others. This paper ends with limitations and implications of the study results.

The purpose of this study was to propose a "user experience (UX)-centered product development process" so that the product design development process using the service design process can be systematized and used in practice. In a situation in which usability research on office phones is lacking compared to general home phones, this study expands to a product-based service design point of view rather than simple product development, intending to research ways to provide user experience value through office phone design in smart office. This study focused on extracting UX-centered user needs using the service design process and developing product design that realizes user experience value. In particular, the service design process was applied to systematically extract user needs and experience value elements in the product development process and to discover ideas that were converged with product-based services. For this purpose, the "Double Diamond Design Process Model," which is widely used in the service design field, was adopted. In addition, a product design development process was established so that usability improvement plans, user experience value elements, and product-service connected ideas could be extracted through a work-flow in which real users and people from various fields participate. Based on the double diamond design process, in the "Discover" information collection stage, design trends were identified mainly in the office phone markets. In the "Define" analysis and extraction stage, user needs were analyzed through user observation, interview, and usability survey, and design requirements and user experience issues were extracted. Persona was set through user type analysis, and user scenarios were presented. In the "Develop" development stage, ideation workshops and concept renderings were conducted to embody the design, and people from various fields within the company participated to set the design direction reflecting design preference and usability improvement plans. In the "Deliver" improvement/prototype development/evaluation stage, a working mock-up of a design prototype was produced and design and usability evaluation were conducted through consultation with external design experts. It is meaningful that it established a "UX-centered product development process" model that converged with the existing product design development process and service design process. Ultimately, service design-based product design development process was presented so that I Corp.'s products could realize user experience value through service convergence.

Websites support various user activities in a wide range of contents domain and so they require different approach to extract principal design problems. In the point of media perspective on websites, this paper figures out the relationship between designer, user and website and discusses design factors of usability. It aims for the basic framework for interface design. In the media perspective website is an information entity mediating user and designer. Information entity is composed of various design factors relating to user, designer, website and others. It intends that user and information entity are accommodative to each other and have common conceptual model. To do so it is necessary for achieving usability objectives such as effectiveness, efficiency and satisfaction based on the understanding user goal, cognitive and affective characteristics. In the point of usability we examine design factors and features that are appropriate for users cognitive and affective function according to information entity model that constitutes contents, organization and representation level.

제품이 가지는 감성적이고 사회적인 기능이 디자이너가 고려해야 할 중요한 요소로 대두되면서, 제품 디자인은 제품 자체를 분석하고 개선한다는 소극적인 관점에서 벗어나 사용자의 제품 사용상황을 이해하고 그 안에서 숨겨진 니즈를 파악하여 새로운 사용상황을 제안하는 적극적인 관점으로 그 범위를 넓혀가고 있다. (중략)

디자인 프로세스상에 이미지를 중심으로 하는 시각언어를 통한 디자인 컨셉 커뮤니케이션은 이미 여러 디자인분야에서 여러 가지 방향으로 진행되고 있다(스타일 스케치보드, 이미지 맵, 컬러맵, 캐털로그 리뷰 등). 그러나 대부분의 경우, 디자인 리서치에 사용되어진 이미지들은 리서치 이후 저장되지 않고 폐기되어지기 때문에, 새로운 디자인 작업에서 재활용되어지지 못하는 프로세스상의 단점을 가지고 있다.(중략)

This study was on the investigation of how to adapt Ethnography, main research methodology in Anthropology, to "User-Centered Design Research", which is a recently focused issue in design field. Thus, this paper has highlighted concrete application processes and methods which were adapted in the case study of developing a concept for the new microwave oven. This paper mainly consists of two parts. First, the basic concept of "Ethnography" is introduced based on secondary research, and the concept of "Culture" is defined as the favorable one to design field. This part was done for constructing knowledge basis which is needed in establishing thematicaJ framework of design research. Second, the application methods of Ethnography is demonstrated through the concrete case study of developing a new microwave oven. This second part was composed of three sub-sections, which are an introduction of conducting process of ethnographic deisgn research, a description of analyzed data of kitchen culture and various particularities of usage pattem of microwave oven, and finally, a discussion of the efficiency of ethnography through generating design implications for a new microwave oven. This demonstration of case study suggests the concrete idea of how to adapt ethnography to design research and will contribute to increase more effective ethnographic design research in the future.c design research in the future.
