Developing instantaneous eye-activity based task analysis
Hoe Kin Wong · 2016
Task analysis using eye-tracking has previously been used for estimating cognitive load on a per-task basis. However, since pupil size is a continuous physiological signal, eye-based classification accuracy of cognitive load can be improved by analysing cognitive load at a finer temporal resolution and incorporating models of the interactions between the task-evoked pupillary response (TEPR) and other pupillary responses such as the pupillary light reflex into the classification model.
