Abstract

Mobile phones are becoming the most widespread personal consumer device. Yet, offering mobile access anywhere, anytime for anybody poses new challenges to usability. So far there is little research on how to customize usability heuristics to the specific characteristics of mobile phone applications. Therefore, this article presents a set of tailored usability heuristics based on a systematic literature review. In order to facilitate the usage of these heuristics, the authors design and validate a measurement instrument checklist and scale. The checklist has been validated through an empirical study in which the results of 247 heuristic evaluations have been statistically analyzed using Item Response Theory. Based on the results, the measurement items have been calibrated and a standardized measurement scale has been constructed. The results can be used to measure usability of mobile phone applications from early on in the design process, and, thus, facilitate evaluations in a cost-effective way.

基于启发式的手机应用程序可用性评分

移动电话正在成为最普遍的个人消费设备。然而，随时随地为任何人提供移动访问对可用性提出了新的挑战。到目前为止，关于如何根据手机应用的具体特点定制可用性启发式的研究还很少。因此，本文在系统回顾文献的基础上，提出了一套量身定制的可用性启发式方法。为了方便这些启发式的使用，作者设计并验证了测量仪器清单和量表。运用项目反应理论对247个启发式评价结果进行了统计分析，并通过实证研究对清单进行了验证。在此基础上，对测量项目进行了标定，并构建了标准化的测量量表。这些结果可以用于在设计过程的早期测量移动电话应用程序的可用性，并且，因此，以具有成本效益的方式促进评估。
