论文摘要
背景：缺乏可用性可能是快速采用移动服务的主要障碍。因此，本文的目的是调查孟加拉国移动健康应用的可用性。 方法：我们在研究中采用了三阶段的方法。首先，我们在流行的应用商店中进行了基于关键字的应用程序搜索。我们遵循亲和力图方法，并将发现的应用聚集到九组中。其次，我们从每个组中随机选择了四个应用程序（总共36个应用程序），并进行了启发式评估。最后，我们从每个组中选择了下载最高的应用程序，并与30名参与者进行了用户研究。 结果：我们发现61％的可用性问题是启发式检查中的灾难或主要性质。最多的（21％）违反了启发式的是美学和极简主义的设计。用户研究显示，基于启发式评估，这些应用程序的系统可用性量表（SUS）得分较低。因此，启发式评估和用户研究的结果相互补充。 结论：总体而言，调查结果表明，孟加拉国移动健康应用程序的可用性一般并不令人满意，并且可能是更广泛采用移动卫生服务的潜在障碍。
Background: Lack of usability can be a major barrier for the rapid adoption of mobile services. Therefore, the purpose of this paper is to investigate the usability of Mobile Health applications in Bangladesh. Method: We followed a 3-stage approach in our research. First, we conducted a keyword-based application search in the popular app stores. We followed the affinity diagram approach and clustered the found applications into nine groups. Second, we randomly selected four apps from each group (36 apps in total) and conducted a heuristic evaluation. Finally, we selected the highest downloaded app from each group and conducted user studies with 30 participants. Results: We found 61% usability problems are catastrophe or major in nature from heuristic inspection. The most (21%) violated heuristic is aesthetic and minimalist design. The user studies revealed low System Usability Scale (SUS) scores for those apps that had a high number of usability problems based on the heuristic evaluation. Thus, the results of heuristic evaluation and user studies complement each other. Conclusion: Overall, the findings suggest that the usability of the mobile health apps in Bangladesh is not satisfactory in general and could be a potential barrier for wider adoption of mobile health services.
