Abstract
In this paper we present an adapted usability evaluation framework to the context of a mobile computing environment. Using this framework, we conducted a qualitative meta-analytical review of more than 100 empirical mobile usability studies. The results of the qualitative review include (a) the contextual factors studied; (b) the core and peripheral usability dimensions measured; and (c) key findings in the form of a research agenda for future mobile usability research, including open and unstructured tasks are underutilized, interaction effects between interactivity and complexity warrant further investigation, increasing research on accessibility may improve the usability of products and services for often overlooked audiences, studying novel technology and environmental factors will deepen contextual mobile usability knowledge, understanding which hedonic factors impact the aesthetic appeal of a mobile device or service and in turn usability, and a high potential for neuroscience research in mobile usability. Numerous additional findings and takeaways for practitioners are also discussed.
Practitioner’s Take Away
The following are key points raised in this paper:
- Consider the wide range of usability dimensions identified in this study when evaluating the usability of mobile interfaces and applications.
- Design mobile interfaces and applications that fit particular contextual settings, while being flexible to accommodate others.
- Focus beyond the interface—usability is an aggregate experience—when developing applications.
- Study the human factors in HCI, and identify cognitive factors and physical abilities that future mobile devices could be designed to accommodate.
- Consider the limitations of the laboratory and conduct research involving real (not simulated) and open tasks through field studies that will offer rich and relevant findings.
- Explore the interplay among dynamic factors (e.g., urgency, noise) and their impact on mobile usability.
