Abstract
Provided are a method and an apparatus for detecting a delay amount of an eyeball tracking apparatus, an eyeball tracking system, and a non-transitory computer-readable storage medium. The method includes: receiving a detected gaze point coordinate of a mechanical eye at the at least one detection time point; determining an actual gaze point coordinate of the mechanical eye at the at least one detection time point; and determining the delay amount of the eyeball tracking apparatus according to a coordinate difference between the actual gaze point coordinate and the detected gaze point coordinate at the at least one detection time point.
