Abstract

The mobile and wearable nature of smartwatches poses challenges in evaluating their usability. This paper presents a study employing customized heuristic evaluation and use of the system usability scale (SUS) on four smartwatches, along with their mobile applications. A total of 11 heuristics were developed and validated by experts by combining Nielsen’s heuristic and Motti and Caines’ heuristics. In this study, 20 participants used the watches and participated in the SUS survey. A total of 307 usability issues were reported by the evaluators. The results of this study show that the Galaxy Watch 5 scored highest in terms of efficiency, ease of use, features, and battery life compared to the other three smartwatches and has fewer usability issues. The results indicate that ease of use, features, and flexibility are important usability attributes for future smartwatches. The Galaxy Watch 5 received the highest SUS score of 87.375. Both evaluation methods showed no significant differences in results, and customized heuristics were found to be useful for smartwatch evaluation.

使用定制启发式方法和系统可用性量表评分评估可穿戴智能手表的可用性

智能手表的移动和可穿戴特性为评估其可用性带来了挑战。本文介绍了一项采用启发式评估和系统可用性量表（SUS）对四款智能手表及其移动应用程序进行定制化评估的研究。通过结合尼尔森启发式以及莫蒂和凯恩斯的启发式，共开发了 11 种启发式，并由专家进行了验证。在这项研究中，20 名参与者使用了手表并参与了 SUS 调查。评估人员共报告了 307 个可用性问题。研究结果表明，与其他三款智能手表相比，Galaxy Watch 5 在效率、易用性、功能和电池续航时间方面得分最高，可用性问题较少。结果表明，易用性、功能和灵活性是未来智能手表的重要可用性属性。Galaxy Watch 5 的 SUS 得分最高，为 87.375 分。两种评估方法的结果没有明显差异，定制启发式方法对智能手表评估很有用。

期刊介绍： Future Internet is a scholarly open access journal which provides an advanced forum for science and research concerned with evolution of Internet technologies and related smart systems for “Net-Living” development. The general reference subject is therefore the evolution towards the future internet ecosystem, which is feeding a continuous, intensive, artificial transformation of the lived environment, for a widespread and significant improvement of well-being in all spheres of human life (private, public, professional). Included topics are: • advanced communications network infrastructures • evolution of internet basic services • internet of things • netted peripheral sensors • industrial internet • centralized and distributed data centers • embedded computing • cloud computing • software defined network functions and network virtualization • cloud-let and fog-computing • big data, open data and analytical tools • cyber-physical systems • network and distributed operating systems • web services • semantic structures and related software tools • artificial and augmented intelligence • augmented reality • system interoperability and flexible service composition • smart mission-critical system architectures • smart terminals and applications • pro-sumer tools for application design and development • cyber security compliance • privacy compliance • reliability compliance • dependability compliance • accountability compliance • trust compliance • technical quality of basic services.
