Resumo
© Springer Nature Switzerland AG 2019.This work investigates the use of eye-tracking as a method for analysis of mental effort in cognitive tasks. From a trivial task of counting objects, the proposal of this work is to present a study on the reactions of the nervous system through visual stimuli to the cognitive system. Our experimental results show that there is a relationship between the cognitive load and pupillary diameter variation, reinforcing the idea that the pupil is a sensitive indicator of mental effort. We believe that pupil diameter measurement can be used as a performance descriptor in cognitive tasks.
