当两人一起完成一项物理任务时，看到一个共同的工作空间有利于他们的表现，并改变他们对语言的使用。先前的研究结果表明，视觉信息有助于协作对了解他们的任务的当前状态，他们的对话，并有效地沟通。然而，协作技术往往会影响支持成功协作所需的视觉信息。这方面的一个例子是在协作环境中引入延迟视觉反馈。我们目前的结果从两项研究，详细的功能，描述视觉延迟和协作任务性能之间的关系的形式。第一项研究精确地展示了一系列视觉延迟如何不同地影响性能和所采用的协作策略。第二项研究描述了任务的参数，如视觉环境的动态，减少可以容忍的延迟量。
When pairs work together on a physical task, seeing a common workspace benefits their performance and transforms their use of language. Previous results have demonstrated that visual information helps collaborative pairs to understand the current state of their task, ground their conversations, and communicate efficiently. However, collaborative technologies often impinge on the visual information needed to support successful collaboration. One example of this is the introduction of delayed visual feedback in a collaborative environment. We present results from two studies that detail the form of the function that describes the relationship between visual delay and collaborative task performance. The first study precisely demonstrates how a range of visual delays differentially impact performance and the collaborative strategies employed. The second study describes how parameters of the task, such as the dynamics of the visual environment, reduce the amount of delay that can be tolerated.
