Developing Elements of User Experience for Mobile Phones and Services: Survey, Interview, and Observation Approaches

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 observation captured daily experiences of eight end‐users with mobile phones. This study collected various views on UX from academia, industry, and end‐users using these three approaches. As a result, this article proposes definitions of UX and its elements: usability, affect, and user value. These results are expected to help design products or services with greater levels of UX.
