Experimental evidence indicates that saccadic metrics vary with task difficulty and time-on-task in naturalistic scenarios. We explore historical and recent findings on the correlation of saccadic velocity with task parameters in clinical, military, and everyday situations, and its potential role in ergonomics. We moreover discuss the hypothesis that changes in saccadic velocity indicate variations in sympathetic nervous system activation; that is, variations in arousal.
实验证据表明，在自然场景中，眼跳度量随任务难度和任务时间而变化。我们探讨了眼跳速度与临床、军事和日常情况下任务参数的相关性的历史和最新发现，以及其在工效学中的潜在作用。此外，我们还讨论了这样一种假设，即眼跳速度的变化表明交感神经系统激活的变化，也就是说，警觉度的变化。
