Feasibility of evaluating temporal changes in cognitive load factors using ocular features

Published: 25 May 2021 Publication History

Abstract

In this paper, we have focused on microsaccade, pupil diameter and eye movements to discover the relationship between cognitive load. In detail, we have confirmed the relevance of factors of mental workload and oculomotor reactions. Utilizing a visual search task, we measured how eye features change by combining subjective evaluation assessment data. To evaluate the amount of cognitive load gained, we used a systematic evaluation index, NASA-TLX and analyzed with correct rate and reaction time. As a result, we have discovered that oculomotor indices brings correlation relationship on specific cognitive load items.
