In this paper, we propose a novel concept of the gaze window, which follows the user's gaze to show relevant information close to their gaze point on a screen space. We explore the use of a gaze window, especially for two use cases: (1) a single‐user data entry task by displaying data‐source image close to the gaze point where the data are typed in and (2) a teleconferencing setup showing a remote partner close to the gaze point. To investigate the performance of gaze window in these cases, we conducted two experiments. For the single‐user task, we compared the gaze window with a baseline non‐gaze‐window condition and found that the gaze window significantly reduced the user's gaze movement and mental effort and increased usability. In the teleconferencing task, we compared displaying partner close to gaze point in the gaze window to displaying partner at the corner of screen, when two remote users watch a shared and synchronized content together. We found that displaying the partner's face nearby the user's gaze helped the user look at the partner more frequently, and for a longer time, significantly increasing co‐presence and emotional interdependence. As a result of this research, we also presented design guidelines for gaze‐window systems.

凝视窗口：一个新的凝视界面，显示靠近凝视点的相关内容

在本文中，我们提出了一种新颖的注视窗口概念，它遵循用户的注视，以在屏幕空间上靠近他们的注视点的位置显示相关信息。我们探讨了凝视窗口的用法，特别是针对两个用例：（1）通过在靠近输入数据的凝视点附近显示数据源图像来显示单用户数据输入任务，以及（2）显示电话会议设置靠近凝视点的远程伙伴。为了研究在这些情况下的凝视窗性能，我们进行了两个实验。对于单用户任务，我们将凝视窗口与基准非凝视窗口条件进行了比较，发现凝视窗口显着减少了用户的凝视运动和精神努力，并提高了可用性。在电话会议任务中，当两个远程用户一起观看共享和同步的内容时，我们将凝视窗口中凝视点附近的显示伙伴与屏幕角处的显示伙伴进行了比较。我们发现，在用户的凝视附近显示伴侣的脸有助于用户更频繁地注视伴侣，并且时间更长，这显着增加了共存和情感上的相互依赖。这项研究的结果是，我们还提出了凝视窗系统的设计指南。
