receive eye-movement data from the eye-tracking device, the eye-movement data comprising pupil dilation event data taken during a saccade event and pupil dilation event data taken during a fixation event,
apply a processing function to the eye-movement data to generate processed eye-movement data as a ratio of the pupil dilation event data taken during the saccade event relative to the pupil dilation event data taken during the fixation event,
apply a classification function to the processed eye-movement data to detect a cognitive load associated with the processed eye-movement data and corresponding to a visual location of a field of view of the user, the cognitive load indicating an amount of cognitive resources used by a user when processing information, and
output a notification regarding the cognitive load associated with the processed eye-movement data.
