Concept of User Experience and Issues to be Discussed

The origin of the concept of UX (User Experience) is first reviewed within the context of usability studies. Then the brief history of the UX concept, the publication of the UX white paper, and the relation with the hedonic aspects are surveyed. In the latter half, the author’s view in terms of the following aspects of the UX are discussed: (1) the processing model of cognition (information) and emotion (valence), (2) the importance of the meaningfulness, (3) the lifecycle model of the UX, (4) the inadequacy of using the word “use” and “user,” and (5) the application of social psychological model of impression formation.
