在这项研究中,我们探讨使用指向和绘图在远程协作系统。我们的应用程序允许本地用户与平板电脑上的桌面计算机与远程专家进行通信。我们比较了四种情况下的性能:(1)静态图像上的指针,(2)实时视频上的指针,(3)静态图像上的注释,以及(4)实时视频上的注释。我们发现,使用工程图注释将需要更少的专家方面的输入,并将需要更少的认知负荷的本地工人方面。在后续研究中,我们使用更复杂的任务比较了条件(2)和(4)。我们发现,指向输入需要良好的口头沟通才能有效,并且在完成任务的每一步后需要删除绘图注释。
In this research, we explore using pointing and drawing in a remote collaboration system. Our application allows a local user with a tablet to communicate with a remote expert on a desktop computer. We compared performance in four conditions: (1) Pointers on Still Image, (2) Pointers on Live Video, (3) Annotation on Still Image, and (4) Annotation on Live Video. We found that using drawing annotations would require fewer inputs on an expert side, and would require less cognitive load on the local worker side. In a follow-on study we compared the conditions (2) and (4) using a more complicated task. We found that pointing input requires good verbal communication to be effective and that drawing annotations need to be erased after completing each step of a task.
