Abstract

In mobile content services like apps for smart mobile devices in specific, there has been a growing interest in evaluating UX quality to make sure that it provides better experience to users and consequently, secures competitiveness in a market. In that sense, usability testing has been considered as one method that enables designers and design managers to evaluate UI quality before they launch their service. However, those designers have been faced with a following fundamental question to be answere d : Is good UX design a good business? In other words, can well-designed service, which has good usability, actually satisfy target users and improve competitiveness in a market? There is no doubt that usability is one important factor perceived by users. However, it has a limit in terms of evaluating UX quality in macro level, as it mostly focuses on ease of use and efficiency of performing tasks, but does not cover other possible experiential factors, which also can be perceived by users, such as market situation and preexistence experience. Therefore, this research aims to identify key experiential factors in using mobile content services, and establish service UX index model that enables to measure perceived user satisfaction, and identify how UX design contributes to the satisfaction in quantitative way.

사용성 평가는 User Interface(UI)의 완성도를 진단할 수 있다는 측면에서 UX 디자인 프로세스 전반에 걸쳐 활용되고 있다. 그러나 컨텐츠 기반 서비스의 경우 서비스가 실제 시장에서 어떻게 사용자들에게 지각되고, 어떤 경험 요소들이 서비스에 대한 만족도를 결정하는 데 영향을 미치는지 등을 파악하는 데는 사용성 평가만으로는 한계가 있을 수 있다. 비록 사용성이 사용자 경험에 영향을 미치는 중요한 하나의 요소이나, 그 외에 다양한 사용자의 주관적인 태도, 시장 성숙도 및 경쟁 현황 등 시장에서 발생할 수 있는 환경적인 변수 등은 포괄하지 못하기 때문이다. 이에 본 연구를 통해 사용성뿐만 아니라 실제 시장에서 사용자 만족도에 영향을 주는 다양한 내적, 외적 경험 요소들을 밝히고자 하였으며, 이를 통해 모바일 컨텐츠 기반 서비스에서 사용자가 경험하는 전반을 정량적으로 평가하고 진단할 수 있는 UX 인덱스 모델을 구축하였다. 또한 설계된 UX 인덱스를 기반으로 실제 출시되어 운영 중인 서비스를 대상으로 한 정량 설문 분석을 통해 모델을 검증하고, 결과 데이터를 분석함으로써 본 인덱스에 대한 활용 방안을 제시하고자 하였다.
