如果语境的共享现在被广泛认为是成功交际的一个条件，现有的研究不允许我们确定是否有必要恢复最大限度的共享视觉信息来获得最佳的交际表现。为了解决这个问题，比较了三种由共享视觉信息范围区分的帮助对话条件。重点分析了每个条件引起的理解问题。研究结果强调，帮助对话的理解效率与共享视觉信息的数量并不一定相关。本研究提出了这一观察结果的两个原因：(a)远程帮助对话中的帮助请求者调整其请求的内容以适应共享视觉信息的有效数量，以及(b)帮助者调整其解释策略以适应可用的共享资源。另一方面，研究表明，无法直观地分享某些特定的任务相关信息严重影响了沟通效率。从这些结果中得出了计算机中介通信系统设计的含义。
If the sharing of context is now widely acknowledged as a condition for successful communication, existing studies do not allow us to determine whether it is necessary to restore the maximum of shared visual information to obtain the best communicative performance. To address this issue, three help dialogue conditions distinguished by the range of shared visual information are compared. The analyses are focused on the comprehension problems raised by each condition. The results highlight that comprehension efficiency in help dialogues is not necessarily linked to the quantity of shared visual information. This study suggests two reasons for this observation: (a) Help requesters in remote help dialogues adapt the content of their requests to the effective amount of shared visual information, and (b) helpers adapt their interpretive strategies to the available shared resources. On the other hand, it is shown that the inability to visually share some specific task-related information strongly affects communication efficiency. Implications for the design of computer-mediated communication systems are drawn from these results.
