增强现实(AR)应用程序可以使地理上相距遥远的用户使用共享视频源或交互式3D全息图进行协作,并且在Covid-19大流行的社会距离背景下可能特别有用。然而,良好的用户体验是他们成功的关键,可能会受到网络损害的负面影响,这在当今尽力而为的互联网中是不可避免的。在本文中,我们提出了一个实证用户研究的结果,旨在了解网络中断的影响,对用户体验和行为,在协作AR任务。我们强调了网络中断如何影响用户在不同的方式,这取决于他们在协作任务中的角色,以及如何为用户提供明确的信息,网络条件差,帮助他们处理这些负面影响。此外,我们报告的策略,用户自己采取的,以处理中断,如中断指令,或转移到一个不同的空间参考风格时,与他们的合作伙伴沟通。最后,根据我们的研究结果,我们提出了一些设计未来的远程协作AR应用程序的影响。
Augmented Reality (AR) applications can enable geographically distant users to collaborate using shared video feeds or interactive 3D holograms, and may be particularly useful in the socially distant context of the Covid-19 pandemic. However, a good user experience is key for their success and could be negatively impacted by network impairments, which are an inevitable occurrence in today's best-effort Internet. In this paper, we present the findings of an empirical user study, aimed at understanding the effects of network outages, on user experience and behavior, in a collaborative AR task. We highlight how network outages affected users in different ways depending on their role in the collaborative task, and how giving users explicit information about poor network conditions helped them deal with some of these negative effects. Furthermore, we report the strategies that users themselves adopted, to deal with outages, such as batching instructions, or shifting to a different spatial referencing style when communicating with their partners. Lastly, based on our findings, we present some design implications for future remote-collaborative AR applications.
