眼睛注视跟踪提供了一种与计算机交互的自然且快速的方法。到目前为止，已经提出了许多点击替代方案，每种方案都有自己的优点和缺点。我们专注于最自然的选择方法，即停留，用户只需凝视屏幕上的对象一段预定义的停留时间即可选择该对象。我们研究了停留点击替代方案的三个设计参数，即停留时间、按钮大小和内容位置。设计了两个具有相似用户界面的实验，并分别对 21 名和 15 名参与者进行了实验。在每个实验中，每个参与者都测试了停留时间和按钮尺寸的不同组合。一个实验将内容放置在按钮上以供注视，而另一个实验将内容放置在按钮上方。一个重要的发现是，将内容移到可点击区域之外可以避免意外点击，即点石成金问题。在这种设计中，大按钮和短停留时间的组合最适合最大限度地提高准确性和易用性，因为这种现象被认为是“凝视”问题。
Eye gaze tracking provides a natural and fast method of interacting with computers. Many click alternatives have been proposed so far, each with their own merits and drawbacks. We focus on the most natural selection method, i.e. the dwell, with which a user can select an on-screen object by just gazing at it for a pre-defined dwell time. We have looked at three design parameters of the dwell click alternative, namely dwell time, button size and placement of content. Two experiments, with similar user interfaces, were designed and conducted with 21 and 15 participants, respectively. Different combinations of dwell times and button sizes were tested in each experiment for each participant. One experiment had content placed on the buttons to be gazed at, while the other had content placed above the buttons. One important finding is that moving the content outside the clickable areas avoids accidental clicking, i.e. the Midas Touch problem. In such a design, a combination of big buttons and short dwell times are most suited for maximizing accuracy and ease of use, due to a phenomenon identified as the 'gaze-hold' problem.
