Real-time cognitive load measurement for dynamic modality selection using eye-tracking methods

Abstract

The main concern of this study is designing a framework in which the instructional material whether visual or aural can be presented in accordance with the cognitive capabilities and limitations of the learner. One of the main issues in the simultaneous application of aural and visual modalities is the amount of the capacity of the working memory of the learners and difference between the speed of integration of verbal and visual modalities in the working memory. Therefore, the existence of a dynamic system that can provide an estimation of the cognitive load of the user in the real-time could help the instructor in the presentation of the material.
