我们报告的实证研究的人使用移动的协作系统，以支持维护任务的自行车。结果表明，当现场工作人员有远程专家帮助他们时，他们可以更快、更准确地进行维修。一些对通过共享视频系统连接，其中视频摄像机聚焦于活动工作空间，并且它们通过全双工音频进行通信。对于其他对，要么视频被消除，要么音频被减少到半双工（但不是两者兼而有之）。两人在合作方面的成功并不因通信技术而异。然而，他们协调提供咨询意见的方式确实因通信技术的不同而不同。特别是，当两人有视频连接时，帮助更积极主动，协调不那么明确。研究结果显示了合作的价值，但提出了关于沟通媒体和会话协调对任务绩效的相互作用的问题。
We report an empirical study of people using mobile collaborative systems to support maintenance tasks on a bicycle. Results show that field workers make repairs more quickly and accurately when they have a remote expert helping them. Some pairs were connected by a shared video system, where the video camera focused on the active workspace and they communicated with full duplex audio. For other pairs, either the video was eliminated or the audio was reduced to half duplex (but not both). Pairs’ success at collaboration did not vary with the communication technology. However, the manner in which they coordinated advice-giving did vary with the communication technology. In particular, help was more proactive and coordination was less explicit when the pairs had video connections. The results show the value of collaboration, but raise questions about the interaction of communication media and conversational coordination on task performance.
