TL;DR: Inter-trial change in pupil diameter and microsaccade magnitude appear to adequately discriminate task difficulty, and hence cognitive load, if the implied causality can be assumed and the reliability and sensitivity of task-evoked pupillary andmicrosaccadic measures of cognitive load are compared.

TL;DR: A novel eye-tracked measure of the frequency of pupil diameter oscillation is proposed for capturing what is thought to be an indicator of cognitive load and is shown to discriminate task difficulty vis-a-vis cognitive load in an experiment.

TL;DR: A two-step method of quantifying eye movement transitions between areas of interest (AOIs), where individuals' gaze switching patterns, represented by fixated AOI sequences, are modeled as Markov chains, to determine the overall distribution of attention over AOIs.

TL;DR: The coefficient K, defined on a novel parametric scale, derived from processing a traditionally eye-tracked time course of eye movements, is introduced and quantitatively depicts the difference in scanning behaviors when attention is guided by audio description during perception of art.
