Challenges, Methodologies, and Issues in the Usability Testing of Mobile Applications

Abstract

Usability testing of software applications developed for mobile devices is an emerging research area that faces a variety of challenges due to unique features of mobile devices, limited bandwidth, unreliability of wireless networks, as well as changing context (environmental factors). Traditional guidelines and methods used in usability testing of desktop applications may not be directly applicable to a mobile environment. Therefore, it is essential to develop and adopt appropriate research methodologies that can evaluate the usability of mobile applications. The contribution of this article is to propose a generic framework for conducting usability tests for mobile applications through discussing research questions, methodologies, and usability attributes. The article provides an overview of existing mobil application usability studies and discusses major research questions that have been investigated. Then, it proposes a generic framework and provides detailed guidelines on how to conduct such usability studies.
