Assessing Students' Perceptions of Mobile Applications Usability using System Usability Scale

The purpose of this study is to explore the usability level of the mobile application from the perspectives of students at higher education institutes by using the most used measure of perceived usability, namely, the System Usability Scale (SUS). Furthermore, the study investigated the effect of some of the students’ demographic attributes on mobile application usability. Results revealed that the system usability scale score is 63% which indicated that the mobile application usability is inadequate and requires more attention. Moreover, the results indicated that there is a significant impact of students’ gender on system usability scale scores; while other demographic attributes such as study level, department, usage experience, and device type, did not have impacts on System Usability Scale scores. The results of the study will be helpful to policymakers, top management, and mobile applications developers, in designing mobile applications with high quality in terms of its usability.
