“…Most studies and reviews have found that blink frequency consistently decreases with increased task demand and arousal, and increases with drowsiness [ 15 , 27 , 28 , 42 , 46 ], although some studies found no differences [ 19 , 22 ]. However, like gaze fixation, there is speculation about the impact of task demand on blinking metrics, specifically, tasks that require internally directed attention cause increased blinking and tasks that require externally directed or visual attention cause decreased blinking.…”

Gaze and pupil metrics are used to represent higher cognitive processes in a variety of contexts. One growing area of research is the real-time assessment of workload and corresponding effort in gamified or simulated cognitive and motor tasks, which will be reviewed in this paper. While some measurements are consistent across studies, others vary and are likely dependent on the nature of the effort required by the task and the resulting changes in arousal. Pupil diameter is shown to consistently increase with task effort and arousal; however, the valence of arousal must be considered. In many cases, measures of pupil diameter were sensitive to both excessive and insufficient challenge. Overall, it is evident that gaze and pupil metrics are valuable to assess the cognitive state during gamified and simulated tasks, and further research is indicated regarding their use in clinical populations in rehabilitation to inform optimally engaging interventions.
