VALIDATION OF EYE TRACKING DATA

Abstract

A computer-implemented method of validating eye tracking data for a system for performing eye tracking-based tests or tasks on a subject. The method comprises receiving (S8) eye tracking data of one or both eyes of a subject for each one of a sequence of visual stimuli (200), the eye tracking data indicative of one or more characteristics of the subject's gaze or position when each of the stimuli (200) were displayed. The method comprises receiving (S9) one or more subject indications comprising at least one of the following: the subject's age; one or more pathological or physiological conditions of the subject; and data representative of a calibration quality and/or attention level for one or more previous eye tracking-based tests or tasks performed by the subject. The method also comprises one or more of the following steps: a) quantifying a calibration quality of the eye tracking data and determining (S10) whether the calibration quality is lower than a predetermined minimum expected calibration quality associated with the subject indications, based at least on the eye tracking data the position of each visual stimuli and the subject indications; b) quantifying an attention level of the subject based on the eye tracking data, and determining (S10) whether the attention level of the subject is lower than a predetermined minimum expected attention level associated with the subject indications, based at least on the eye tracking data and the subject indications.
