本文的目的是研究受试者在开始使用注视作为计算机输入时所进行的学习过程。研究人员对8名日本学生进行了为期7天的实验，记录了初学者在输入110个句子时的眼动数据。实验表明，只要输入15-25个句子，相当于大约3-4小时的练习，低效的眼球运动就会显著减少。性能数据符合基于实践幂律的一般学习模型。该学习模型可用于估计注视类型性能的进一步改进。我们的实验结果鼓励重度残疾人使用基于注视的界面。本文对停留时间激活键上的注视动作进行了分类，并提出了一种记录注视界面可学习性的方法。
The aim of this paper is to examine the learning processes that subjects undertake when they start using gaze as computer input. A 7-day experiment with eight Japanese students was carried out to record novice users' eye movement data during typing of 110 sentences. The experiment revealed that inefficient eye movements was dramatically reduced after only 15–25 sentences of typing, equal to approximately 3–4 h of practice. The performance data fits a general learning model based on the power law of practice. The learning model can be used to estimate further improvements in gaze typing performance. Our experimental results encourage the use of gaze-based interfaces for severely disabled people. This paper provides a taxonomy for gaze actions on dwell time-activated keys and it presents a method by which the learnability of gaze interfaces may be documented.
