WebWhen looking at a static object, the head is kept relatively still, and the eyes mainly perform saccadic and fixational movements. However, in dynamic situations where either we or the object of interest is moving, other eye movements are needed to keep the fovea aligned with the point of interest. ... Rayner, K. (2009).

Introduction: Fixational saccades are miniature eye movements that constantly change the gaze during attempted visual fixation. Visually guided saccades and fixational saccades represent an oculomotor continuum and are produced by common neural machinery.
