The Effect of the User Interface Design of Smartphone Applications on Users' Individual Experiences of Performance

摘要

Even though an awareness of the necessity of studying the importance of User Interface (UI) design in the development of smartphone applications has risen among researchers, a current review of the relevant IS literature reveals the existence of a scant understanding of the topic in empirical research terms. Such a review shows that only a small amount of empirical findings have been published on the effect that the UI design of smartphone applications has on the usability of applications, as well as users' individual experiences of performance with a given application. This study aims to examine: (1) the direct effect of UI design on users' individual experiences of performance with a given application, (2) the indirect effect of UI design on users' individual experiences of performance through a mediating variable, which is the usability of applications as perceived by users. The data collected through a survey was analyzed by Structural Equation Modeling (SEM). The results of the analysis show the significant effect of the UI design on both perceived usability and users' individual experiences of performance. In addition, the perceived usability of applications also had a positive impact on users' individual experiences of performance.
