只用眼睛凝视书写文本是一种吸引人的免提文本输入方法。然而，现有的基于凝视的文本输入方法引入眼睛疲劳并且打字速度慢，因为它们通常需要用户停留在单词的字母上，或者用用于输入单词的额外操作来标记凝视路径的开始和结束位置。在本文中，我们提出了一种文本输入方法GlanceWriter，它允许用户通过逐个浏览按键来输入文本，而不需要纠缠于任何按键，也不需要在输入单词时指定凝视路径的开始和结束位置。为了实现这一点，GlanceWriter根据凝视运动和凝视位置的动态变化来概率地确定要打字的字母。我们的用户研究表明，与EyeSwipe相比，GlanceWriter显著提高了文本输入的性能，EyeSwipe是一种无需驻留的输入法，使用“反向交叉”来识别开始和结束键。GlanceWriter的表现也超过了Tobii的通信器5的无驻留凝视输入法，这是一种基于商业眼睛凝视的交流系统。总体而言，GlanceWriter通过对凝视路径的概率解码实现了无驻留和无交叉的文本输入，提供了一种很有前途的基于凝视的文本输入方法。
Writing text with eye gaze only is an appealing hands-free text entry method. However, existing gaze-based text entry methods introduce eye fatigue and are slow in typing speed because they often require users to dwell on letters of a word, or mark the starting and ending positions of a gaze path with extra operations for entering a word. In this paper, we propose GlanceWriter, a text entry method that allows users to enter text by glancing over keys one by one without any need to dwell on any keys or specify the starting and ending positions of a gaze path when typing a word. To achieve so, GlanceWriter probabilistically determines the letters to be typed based on the dynamics of gaze movements and gaze locations. Our user studies demonstrate that GlanceWriter significantly improves the text entry performance over EyeSwipe, a dwell-free input method using “reverse crossing” to identify the starting and ending keys. GlanceWriter also outperforms the dwell-free gaze input method of Tobii’s Communicator 5, a commercial eye gaze-based communication system. Overall, GlanceWriter achieves dwell-free and crossing-free text entry by probabilistically decoding gaze paths, offering a promising gaze-based text entry method.
