Title:
METHOD AND DEVICE FOR MEASURING DELAY AMOUNT OF EYEBALL TRACKING DEVICE, EYEBALL TRACKING SYSTEM, AND NON-TRANSITORY COMPUTER STORAGE MEDIUM
Document Type and Number:
WIPO Patent Application WO/2021/238966
Kind Code:
A1
Abstract:
The present disclosure provides a method and device for measuring the delay amount of an eyeball tracking device, an eyeball tracking system, and a non-transitory computer storage medium. The method comprises: receiving detection fixation point coordinates of a mechanical eye at at least one detection time point; determining actual fixation point coordinates of the mechanical eye at the at least one detection time point; and determining the delay amount of an eyeball tracking device according to the coordinate difference between the actual fixation point coordinates and the detection fixation point coordinates at the at least one detection time point.
