Types of information records [15]

Type of gaze	Explanation
Fixation	Focus images or objects in the fovea, for about 300 msec, during which, the eye remains relatively immobile. Fixation is the action of remaining with the gaze fixed on the same place for a certain amount of time to take in information (read, understand).
Saccadic movements	These are small, rapid, and precise jumps subject to both voluntary and involuntary or induced control, responsible for the recognition and processing of visual information, and associated with head movements. Saccadic movements or saccades are those simultaneous or rapid movements made by the eyes when they move from one point to another in space.
Follow-up	These are slow conjugated tracking eye movements aimed at maintaining fixation on a moving target. The tracking or also considered a visual path is the sum of fixations and saccades.
Restoration of eye torsion	Restoration of eye twisting deals with the rapid closing and opening of blinks, i.e., it is possible to analyze the greater and lesser demand for attention in terms of the object of study.
