The effect of user interface (UI) design decisions on system usability has been discussed in information system literature. These discussions evolved into investigating the effectiveness of UI and how it affects a system user's performance, as well as his or her perception of the system as a whole. This paper investigates the role of UI design on facilitating effective use in the context of mobile applications. Based on the Effective Use Theory, we test four different UIs developed for frequent

Our findings indicate that UI design in terms of touch technique (tap vs. slide) and target direction (vertical vs. horizontal) has a significant impact on the task completion time, as well as the app UIs' perceived usability and likability. We discuss both theoretical and empirical implications of the results and suggest future research directions.
