A Qualitative Review of Empirical Mobile Usability Studies

Abstract

The turn of this century marked an increased focus on mobile usability studies for research in the field of Human Computer Interaction. Such studies offer practitioners the needed insight to deliver usable mobile products and services adopted by consumers at increasing rates contributing to a $20 billion industry. Scholars also benefit by identifying new questions that need to be addressed, thereby enriching our understanding of this dynamic domain within HCI. A challenge for both of these groups exists in that many scholars define and operationalize usability differently. This paper presents a roadmap for future usability research that consists of two parts. First, a framework is adapted for the taxonomy of empirical mobile usability studies. Second, results of the qualitative review of 45 empirical mobile usability studies include: i) the contextual factors studied; ii) the core and peripheral usability dimensions measured; and iii) key findings. Expected contributions of the completed research are also outlined.

Key takeaways

  • Therefore, usability is a more important issue for mobile technology than for other areas, since many mobile applications remain difficult to use, lack flexibility and robustness.
  • Based on the literature review, a qualitative review framework for empirical mobile usability studies is presented next.
  • These four variables (i.e. user, task, environment, technology) will be used for the presentation of the review of previous empirical research that relates to the usability assessment of mobile applications and/or mobile devices.
  • This qualitative review began with the search for empirical mobile usability studies literature.
  • Hence, attitude (as defined in these usability studies) may be collapsed in the single measure of satisfaction.
