Seeing is Believing: The Value of Video for Remote Interpersonal Connections

越来越多的组织正在尝试远程工作。由于旅行耗时、耗力、费钱，他们开始转向远程技术，比如视频和音频会议。当然，高质量的视频比音频要贵得多，而且关于其有效性和必要性的问题也出现了。这个提议提出了两个广泛的问题：1。在什么条件/任务下，添加视频而不是音频才是真正有益的？视频退化的各种情况对用户性能有什么影响？这项研究的重点是视频是否存在对长期团队至关重要的任务的影响，包括建立和维持信任以及发现欺骗。此外，我们还测试了各种合理的信道降级（通常用于降低连接成本）如何在这些情况下改变人们的行为。这项工作既有理论意义又有实践意义。从理论上讲，它揭示了人们在进行重要的社会互动时使用的线索，这些互动是任务相关活动的基础。实际上，我们将能够为那些可能发现自己处于建立信任或在远程互动时发现谎言的情况下的人提供建议。

More and more organizations are attempting to work long distance. Since travel is time consuming, exhausting, and costly, they are turning to remote technologies, such as video and audio-conferencing. High quality video, of course, is much more expensive than audio, and questions arise as to its efficacy and necessity. This proposal asks two broad questions:1. Under what conditions/tasks is the addition of video over audio truly beneficial?2. What effect do various conditions of video degradation have on user performance?The research focuses on the effect of the presence or absence of video on tasks deemed key to long-term teams, involving the establishment and maintenance of trust and the detection of deception. In addition, we test how various reasonable degradations of the channels, those commonly used in making the cost of the connection cheaper, change people's behavior in these situations. This work has both theoretical and practical import. Theoretically, it reveals which cues people use when they engage in important social interactions that underlie task-related activities. Practically, we will be able to provide advice for people who might find themselves in situations involving the building of trust or the detection of lying when that interaction is done remotely.
