Usability Evaluation a Comparative Study in Ecuador, Indonesia, and Lebanon

Usability Evaluation of a Mobile Augmented Reality App for PC Hardware Training: A Comparative Study in Ecuador, Indonesia, and Lebanon. The proliferation of mobile applications for educational purposes has highlighted the need to evaluate their usability, especially in diverse international contexts. This study addresses the problem of insufficient engagement and effectiveness of educational tools related to PC hardware training, a problem exacerbated by cultural and contextual differences between regions. Understanding the importance of this issue is crucial, as effective educational tools can improve learning outcomes and accessibility on a global scale. Previous research has explored various educational technologies, but often failed to comprehensively address usability across different cultural contexts, limiting the generalization and impact of the results. This gap underscores the need for robust evaluation of educational applications in diverse populations. In this context, our research proposes the analysis of Build_PC, a mobile augmented reality (AR) application designed to teach PC hardware, using the IBM Computer System Usability Questionnaire (CSUQ) to assess user satisfaction. This study was conducted in three countries—Ecuador, Indonesia, and Lebanon—covering a variety of cultural and educational settings. The results indicate remarkably high levels of user satisfaction with the AR application across the three participating universities. Positive feedback suggests that the application effectively engages students and improves their understanding of PC hardware training, regardless of regional differences. The implications of these findings are significant, as they suggest that augmented reality applications may be a viable solution for overcoming educational barriers related to PC hardware training on an international scale. This study highlights the potential of such technology to enhance educational outcomes and provides a framework for future research in the global deployment of educational technologies.面向PC硬件培训的移动增强现实（Augmented Reality, AR）应用可用性评估：厄瓜多尔、印度尼西亚与黎巴嫩的对比研究。当前，教育类移动应用的蓬勃普及凸显了对其可用性开展评估的必要性，尤其在多元国际语境下这一需求更为迫切。本研究针对PC硬件培训相关教育工具存在的参与度不足、效果欠佳的问题展开探讨，而区域间的文化与情境差异进一步加剧了这一问题的严重性。明晰该问题的重要性至关重要，因为高效的教育工具可在全球范围内改善学习成效与可及性水平。既往研究虽已探索了多种教育技术，但往往未能全面覆盖不同文化语境下的可用性评估工作，这限制了研究结果的泛化性与实际影响力。这一研究空白凸显了针对多元人群开展教育应用严谨评估的必要性。在此背景下，本研究拟对面向PC硬件教学的移动增强现实应用Build_PC进行分析，采用IBM计算机系统可用性问卷（Computer System Usability Questionnaire, CSUQ）对用户满意度进行评估。本研究在厄瓜多尔、印度尼西亚及黎巴嫩三个国家开展，覆盖了多样化的文化与教育环境。研究结果显示，参与本次研究的三所大学的用户对该AR应用的满意度均处于极高水平。积极的反馈表明，无论区域差异如何，该应用均可有效吸引学生参与学习，并提升其对PC硬件培训内容的理解程度。上述研究发现具有重要的学术与实践意义，其表明增强现实应用或可成为破解全球范围内PC硬件培训相关教育壁垒的可行方案。本研究彰显了此类技术在改善教育成效方面的潜力，并为教育技术全球部署领域的未来研究提供了可供参考的框架。
