“…The human pupil size can regulate the amount of light that enters the eye [ 83 ]. The pupil size, which is the most popular eye-movement index for mapping mental workloads [ 84 , 85 , 86 , 87 ], not only reacts to luminance changes but also reflects cognitive processing. Moreover, pupil size is negatively correlated with the light conditions but is positively correlated with problem difficulty, that is, greater pupillary dilations are observed when the luminance is decreased or the difficulty of the problem is increased [ 88 , 89 , 90 , 91 ].…”

The aim of this study was to investigate how vehicle speed influences the characteristics of driver’s eye movement at highway tunnel entrances during day and night. In this study, six drivers’ eye movement data (from 200 m before tunnel entrance to 200 m inside tunnel entrance) under five predetermined vehicle speeds (40, 50, 60, 70 and 80 km/h) in the daytime and three predetermined vehicle speeds (40, 60 and 80 km/h) in the nighttime were recorded using the non-intrusive Dikablis Professional eye-tracking system. Pupil size, the average fixation duration time and the average number of fixation were analyzed and then the influence of the vehicle speed on these parameters was evaluated by means of IBM SPSS Statistics 20.0. The results for pupil size in daytime increased when approaching the tunnel entrance, while as for nighttime, pupil size decreased when approaching the tunnel entrance and then increased after entering the tunnel. The pupil size in daytime has a significant negative correlation with vehicle speed, while the pupil size in nighttime did not show a significant association with vehicle speed. Furthermore, the average fixation duration in daytime increased when entering the tunnel, and had a significant negative correlation with vehicle speed. Also, the average number of fixations in daytime decreased when entering the tunnel and has a significant negative correlation with vehicle speed. However, the average fixation duration and the average number of fixations in nighttime did not show any significant association with vehicle speed. Moreover, limitations and future directions of the study are discussed for the further investigation.

“…In fact, gaze metrics represent one of the most valid, reliable, and objective indices to assess operator performance [21][22][23], including physicians [24,25]. Specifically, in surgical scenarios, gaze metrics have been used to quantify surgical skills [25][26][27], to study differences between novice and expert surgeons [21,28,29], and to analyze surgeon' scanning behavior [30,31].…”

“…Such questionnaires, easy to administer and interpret, have several methodological caveats, however. Their standard offline administration (paper and pencil test), for example, does not allow for continuous evaluation of CP (Di Stasi, Marchitto, Antol ı, & Cañas, 2013). Thus, the ability to objectively and sensitively measure operator CP online in real scenarios remains a major challenge .…”

Most research connecting task performance and neural activity to date has been conducted in laboratory conditions. Thus, field studies remain scarce, especially in extreme conditions such as during real flights. Here, we investigated the effects of flight procedures of varied complexity on the in-flight EEG activity of military helicopter pilots. Flight procedural complexity modulated the EEG power spectrum: highly demanding procedures (i.e., takeoff and landing) were associated with higher EEG power in the higher frequency bands, whereas less demanding procedures (i.e., flight exercises) were associated with lower EEG power over the same frequency bands. These results suggest that EEG recordings may help to evaluate an operator's cognitive performance in challenging real-life scenarios, and thus could aid in the prevention of catastrophic events.
