视频作为协作工作的支持的研究提供了一点确凿的证据，其效用无论是任务性能或促进远程呈现，即一个面对面的社会存在的远程参与者的输送。到目前为止，大多数关于视频价值的研究都集中在“会说话的头”视频上，其中视频图像是远程参与者一起讨论或执行某些任务。与会说话的头部视频相反，我们研究了视频作为数据，其中工作空间和工作对象的视频图像是感兴趣的焦点，并传达有关工作的关键信息。使用视频作为数据是为了提高任务绩效，而不是提供远程呈现。我们研究了在手术室内和远离手术室的远程位置进行神经外科手术期间视频的使用。视频中显示的工作区是外科医生正在操作的手术区域（大脑或脊柱），我们讨论了我们对使用实时和录制视频的研究结果，并建议扩展视频作为数据，包括其与计算机化的基于时间的信息源的整合，以教育和协调分布式工作组之间的复杂行动。
Studies of video as a support for collaborative work have provided little hard evidence of its utility for either task performance or fostering telepresence, i.e. the conveyance of a face-to-face like social presence for remotely located participants. To date, most research on the value of video has concentrated on “talking heads” video in which the video images are of remote participants conferring or performing some task together. In contrast to talking heads video, we studied video-as-data in which video images of the workspace and work objects are the focus of interest, and convey critical information about the work. The use of video-as-data is intended to enhance task performance, rather than to provide telepresence. We studied the use of video during neurosurgery within the operating room and at remote locations away from the operating room. The workspace shown in the video is the surgical field (brain or spine) that the surgeon is operating on. We discuss our findings on the use of live and recorded video, and suggest extensions to video-as-data including its integration with computerized time-based information sources to educate and co-ordinate complex actions among distributed workgroups.
