摘要

在2019冠状病毒病大流行和强制性全球封锁期间,人们和企业开始广泛使用视频会议应用程序来保持联系。这种需求的激增和视频会议服务的可用性在南非等发展中国家被严重忽视,在南非,三分之一的成年人依靠移动设备上网,每千兆字节的数据成本是非洲最高的。考虑到这些数字,我们进行了一项双管齐下的研究,1)我们通过数据测量实验测量不同Android应用程序的数据消耗,2)我们对带宽受限的用户进行访谈和可用性评估,以更好地了解移动视频会议应用程序的可用性和体验质量(QoE)。可用性是指特定用户使用产品实现特定目标的程度。相比之下,QoE衡量的是对应用程序质量的主观感知,以及对服务的满意或不满意程度。这项研究的主要好处是,通过让组织了解影响用户QoE的因素,让他们了解这些工具的相对可用性。

Investigating the Usability and Quality of Experience of Mobile Video-Conferencing Apps Among Bandwidth-Constrained Users in South Africa
During the COVID-19 pandemic and mandated global lockdowns, people and busi- nesses started the extensive use of video-conferencing applications for staying connected. This surge in demand and the usability of video-conferencing services has been severely overlooked in developing countries like South Africa, where one-third of adults rely on mo- bile devices to access the internet, and the per-gigabyte data cost is among the highest in Africa. Considering these numbers, we conduct a two-pronged study where 1) we measure data consumption of different Android apps through data measurement experiments and 2) we conduct interviews and usability assessments with bandwidth-constrained users to bet- ter understand the usability and Quality of Experience (QoE) of mobile video-conferencing apps. Usability is the degree to which specified users can use a product to achieve specified goals. In contrast, QoE measures the subjective perception of the quality of an application and the level of delight or annoyance with a service. The key benefit of this study will be to inform organisations that seek to be inclusive about these tools’ relative usability by letting them know about the factors influencing users’ QoE.
