User Experience of Mobile Application's Interface

Abstract

With the rapid development of wireless network technology, mobile devices offer better and versatile functions and services than ever before. As the part that users can frequently interact with in whole system, user interface allows the users to experience the system directly. To improve the users' appraisal and satisfaction with the system, it is important to understand the user experiences from the interaction between the users and the interface. However, due to the characteristics of mobile devices, such as the small screen size, mobility and user's short-term memory, mobile devices are significantly different from personal computer. It is not suitable to apply the existing scales directly to the mobile application interface. Thus, this study combined the exiting scales with the construct which is an important concept of the mobile application interface, to develop a scale which can be employed to measure user experience of mobile application's interface.Through the literature review, expert reviews and exploratory factor analysis based on 581 valid questionnaire responses, the study extracts five constructs, namely, information quality, cognitive load, error resolution, visual aesthetic and system attitude, a total of 43 measurement items. This new scale can be reference for interface design of mobile application for practitioners to improve the user mobile experience. The study also established a research model and tried to investigate the relationship among above five constructs. The analysis based on 581 valid data shows that cognitive load and error resolution play full mediators of the relationship between information quality and system attitude. The result provides a new direction for this line of research.
