许多研究表明，视觉注意力和微跳视（一种注视性眼球运动）之间存在关系。视觉注意可以分为自上而下注意和自下而上注意。然而，这些类型的注意力对微扫视的影响还没有得到澄清。此外，包括快速扫视的眼动研究的实际应用值得评价。在本文中，我们研究了自上而下的注意和自下而上的注意对从包含眼跳的眼动数据中提取的微眼跳的影响。眼动，瞳孔直径和反应时间进行了测量，在五个控制实验条件下，需要不同的处理负荷。图像特征、瞳孔直径和响应时间表明实验条件配置合理。统计分析表明，在五个实验条件下，微扫视表现出不同的行为。这一结果表明，视觉注意和加工负荷影响微跳视行为，并可用于估计视觉注意所需的加工负荷。
A number of studies have suggested a relationship between visual attention and microsaccades, a type of fixational eye movement. Visual attention can be classified as Top down attention and Bottom up attention. However, the effect of these types of attention on microsaccades has not been clarified. Further, the inclusion of rapid saccades in research on eye movement for practical applications warrants evaluation. In this paper, we investigated the effect of Top down attention and Bottom up attention on microsaccades extracted from eye movement data which includes saccades. Eye movement, pupil diameter and response time were measured under five controlled experimental conditions requiring different processing loads. The image features, pupil diameters and response times indicated that the experimental conditions were properly configured. Statistical analysis indicated that microsaccades showed different behaviors under each of the five experimental conditions. This result suggested that visual attention and processing loads affect behaviors of microsaccade, and can be used to estimate the required processing load by visual attention.
