Discussion

Observational analysis reveals that fixational saccades depend on both spatial and temporal factors, suggesting precise control mechanisms.

Fixational saccades are crucial for correcting minor fixation errors, especially during steady gaze, and vary in response to spatial cues.
The latency of fixational saccades increases when fixation errors decrease, indicating a sophisticated timing mechanism at work.
Using gaze-contingent procedures, this research directly estimated the perceived center of the visual field in subjects of both sexes.
Findings highlight the interplay between accurate microsaccade generation and timely suppression of unnecessary movements to maintain gaze.

Wang et al. (2025) studied this question.
