在以往的微跳视研究中,一种典型的基本实验方法是:在显示器的中间或靠近中间的位置显示一个点作为视觉目标,测量受试者的眼动,然后从测得的眼动中提取微跳视次数。然而,难以确定被摄体在注视目标的同时是否正在进行视觉注意以及被摄体进行的视觉注意的程度。本文提出了一个系统,使用微眼跳分类视觉目标注视过程中的视觉注意水平。在我们的实验中,10名受试者执行了三个任务,需要不同水平的视觉注意力。测量微扫视,并提取每个任务的微扫视次数。统计分析表明,微扫视的数量不同的任务。我们的研究结果表明,视觉注意水平可以分类的微扫视的数量。
In the previous researches on microsaccades, a typical and basic experimental method involves the following: a dot is displayed as a visual target in the middle or near the middle of a monitor, and eye movements of the subject are measured, and then the number of microsaccades is extracted from the measured eye movements. However, it is difficult to determine whether or not the subject is paying visual attention while gazing at the target, and the degree of visual attention paid by the subject. This paper proposes a system that uses microsaccades to classify visual attention levels during visual target gazing. In our experiment, ten subjects performed three tasks requiring different levels of visual attention. Microsaccades were measured and the number of microsaccades was extracted for each task. Statistical analysis showed that the number of microsaccades differed among the tasks. Our results suggest that visual attention level can be classified by the number of microsaccades.
