“…a decrease in SPV together with an increase in PDR with TOT, have also been reported as a result of increase in mental load 16 . In addition, saccades and fixations having originated from distinct neural control circuits 56 , as well as the co-occurred changes in saccadic and fixation-based oculometrics found in the current study, may support that the fatigue development modulates activations in both of the distinct neural circuits.…”

“…The task was previously shown to be able to impose different levels of mental load 16 . The graphic user interface (GUI) of the computer task was displayed on a 19-in screen (1280 × 1024 pixels, refresh rate: 120 Hz) locating approx.…”

“…The duration of memorization, washout and replication period were set to be 2.34, 2.34, and 5.06 s, respectively. This corresponded to a medium load setting 16 . In this setting, the angles in the patterns made by the five points were >60°, the distance between points was approximately in the range between 2° to 4° in the pattern presentation panel.…”

“…saccades, blinks, fixations, and pupillary responses, involve different neural circuitries in connection with visuomotor information processing 15 . A number of studies 9,16,17 have suggested that saccade peak velocity (SPV), saccade duration (SCD), fixation duration (FD), blink duration (BD), blink frequency (BF), and pupil dilation range (PDR) may be sensitive to mental load variation and fatigue (Table 1 presents definitions of the terms).…”

Fatigue can develop during prolonged computer work, particularly in elderly individuals. This study investigated eye movement characteristics in relation to fatigue development. Twenty young and 18 elderly healthy adults were recruited to perform a prolonged functional computer task while their eye movements were recorded. The task lasted 40 minutes involving 240 cycles divided into 12 segments. Each cycle consisted of a sequence involving memorization of a pattern, a washout period, and replication of the pattern using a computer mouse. The participants rated their perceived fatigue after each segment. The mean values of blink duration (BD) and frequency (BF), saccade duration (SCD) and peak velocity (SPV), pupil dilation range (PDR), and fixation duration (FD) along with the task performance based on clicking speed and accuracy, were computed for each task segment. An increased subjective evaluation of fatigue suggested the development of fatigue. BD, BF, and PDR increased whereas SPV and SCD decreased over time in the young and elderly groups. Longer FD, shorter SCD, and lower task performance were observed in the elderly compared with the young group. The present findings provide a viable approach to develop a computational model based on oculometrics to track fatigue development during computer work.

Lying requires a long-term memory search and is a cognitive load task. Telling a spontaneous lie is associated with a higher cognitive load compared with the truth, although when memories are planned before telling a lie, the cognitive load can be less compared with the truth; therefore, telling a spontaneous lie could be associated with a higher cognitive load compared with a planned lie. In this study, we examined cognitive load, as measured through oculometrics, to identify deceit in interviews. Twenty-four subjects were questioned, and their answers classified as spontaneous lies, planned lies, and truths. Results show that saccades and fixations were associated with a higher cognitive load when telling spontaneous lies compared with telling truths. Blinks and pupillometry show that subjects require greater cognitive load when telling truths compared with planned lies. Finally, telling spontaneous lies required higher cognitive load compared with planned lies, as assessed by blinks.
