Paper Abstract

In several domains, we found increasing demands to assess cognitive workload and fatigue. This article presents part of the work produced towards the implementation of an integrated system composed of an Electroencephalography (EEG) device and an eye-tracker, focusing on the optical devices. Pupil dilation was found to be related to task difficulty and cognitive workload, where dilation of the pupils indicate greater mental workload. This and other optical parameter can act not only as complement to the EEG system but also as a cross-validation tool. Lenses adjustments and calibration process of the eye-tracker are discussed along with preliminary results from pre-test of the experiment protocol.
