To better understand the problem of referencing a location in space under time pressure, we had two remotely located partners (A, B) attempt to locate and reach consensus on a sniper target, which appeared randomly in the windows of buildings in a pseudorealistic city scene. The partners were able to communicate using speech alone (shared voice), gaze cursors alone (shared gaze), or both. In the shared-gaze conditions, a gaze cursor representing Partner A's eye position was superimposed over Partner B's search display and vice versa. Spatial referencing times (for both partners to find and agree on targets) were faster with shared gaze than with speech, with this benefit due primarily to faster consensus (less time needed for one partner to locate the target after it was located by the other partner). These results suggest that sharing gaze can be more efficient than speaking when people collaborate on tasks requiring the rapid communication of spatial information.

为了更好地理解在时间压力下定位空间位置的问题，我们让两个远程的合作伙伴（A、B）尝试定位并就一个狙击手目标达成共识，该目标随机出现在一个拟真城市场景的建筑物窗口中。合作伙伴仅使用语音（共享语音）、光标（共享注视）或两者都可以进行交流。在共享注视的条件下，代表伙伴 A 的眼睛位置的光标叠加在伙伴 B 的搜索显示上，反之亦然。与使用语音相比，使用共享注视时，空间参考时间（双方都找到并同意目标的时间）更快，这主要是因为共识更快（在另一个合作伙伴找到目标后，一个合作伙伴找到目标所需的时间更少）。这些结果表明，在需要快速交流空间信息的任务中，共享注视比说话更有效率。本文的补充材料可从以下网址下载：http://pbr.psychonomic-journals.org/content/supplemental。
