Sung H. Han 교수의 연구실은 사용자 경험(User Experience, UX)과 제품 설계의 상호작용을 중심으로 한 인간요구요소(인간공학) 기반의 응용 연구를 수행합니다. 특히 UX의 요소 분해, 사용자 만족도와 디자인 요소 간의 관계 모델링, 상황에 따른 경험의 변화 과정 분석을 통해 실질적인 제품 개선 방안을 도출합니다. 다국적 소비자 비교, 고객 여정 맵(CJM) 설계 프로세스 개발, 상징적 소비 행동의 동적 모델링 등 다각도의 접근을 통해 사용자 중심의 설계 이론과 실천을 연결합니다.

Abstract The term user experience (UX) encompasses the concepts of usability and affective engineering. However, UX has not been defined clearly. In this study, a literature survey, user interview and indirect observation were conducted to develop definitions of UX and its elements. A literature survey investigated 127 articles that were considered to be helpful to define the concept of UX. An in‐depth interview targeted 14 hands‐on workers in the Korean mobile phone industry. An indirect observ
A fundamental assumption in this paper is that user satisfaction depends on product design. The approach consists of 5 steps: (1) define user satisfaction, (2) decompose product design elements, (3) conduct experiments, (4) develop relationship models, and (5) analyse critical design features. In order to demonstrate the practicability of this approach, relationship models were developed based on experimental data using a total of 60 subjects (30 American and 30 Korean subjects). In addition, cr
Abstract A variety of mobile phones are available to consumers. They differ from each other in many design features including shape, color, size, and material. This study attempts to identify some of the design features of a mobile phone critical to user satisfaction. Empirical models linking design features to satisfaction levels were developed and used to identify critical design features. Design properties common to “desirable” and “undesirable” phones were then extracted by comparing the val
Abstract A customer journey map (CJM) is a widely used tool to represent user experience with a service. Although numerous companies have used this tool to improve existing services or to develop new services, the maps are neither consistent nor mutually compatible because no clear design process for a CJM has been presented. This study aimed to develop a design process and rule sets for a CJM based on a human factors approach. The 10‐step process and the rule sets were built on case studies of
Purpose The purpose of this paper is to investigate the dynamic process and the meaning of symbolic consumption according to the three symbolic needs (i.e. status needs, social needs, status and social needs) to understand how symbolic messages are conveyed when consumers choose a brand. Design/methodology/approach This paper develops three dynamic models, categorized according to the consumers’ needs. The conceptual framework consists of the six constructs: collectivism/individualism, brand rep
