“…For example, Ahlstrom and Friedman-Berg (2016) found that average pupil size increased when controllers used a static storm forecast tool compared to when controllers used a dynamic forecast tool [23]. For the unobtrusive measurement of the pupillary responses, we employed a cognitive load algorithm that automatically models and subtracts size changes due to the pupillary light response based on empirical models of the pupillary light response and camera-based brightness measures, thereby, providing a measure of cognitive load free of this source of pupil size variation [22,[24][25][26]. Here, we did not find any effects of our manipulation of task performance (see Section 3.3).…”

“…Figure 8 shows an example of how this works. Here, one can see how the pupil size of a participant changed during the MATB-II's subtasks, as well as the calculated change in cognitive load, and the calculated light changes that were modelled via the Pupillary-Light-Response (PLR) model [25,26]. This model predicts the pupillary light reflex behavior to brightness via an individually trained empirical model.…”

“…With respect to situational factors, they include cognitive effort and user performance. The most reliable way to track individual cognitive load of the user is the analysis of physiological parameters, such as pupil dilation, eye activity, Galvanic skin response, cerebral activity, body temperature and heart rate variability [38]- [40]. The measurement is done by means of proximal and distal measurement techniques.…”
