Miniature eye movements occur involuntarily during visual fixation. The most prominent contribution to these fixational eye movements is generated by microsaccades, which are rapid small-amplitude saccades with a rate of about one per second. Recent work demonstrates that microsaccades are optimized to counteract perceptual fading during perception of a stationary scene. Furthermore, microsaccades are modulated by visual attention and turned out to generate rich spatio-temporal dynamics. We conclude that the investigation of microsaccades will evolve into a new research field contributing to many facets of oculomotor control, visual perception, and the allocation of attention.
在视觉注视过程中会不由自主地出现微小的眼动。对这些注视性眼动贡献最为显著的是微扫视，它是快速的小幅度扫视，频率约为每秒一次。最近的研究表明，微扫视经过优化，可在感知静止场景时抵消感知消退。此外，微扫视受视觉注意力调节，并且呈现出丰富的时空动态。我们得出结论，对微扫视的研究将发展成为一个新的研究领域，为眼动控制、视觉感知和注意力分配的多个方面做出贡献。
