Digital biomarker of mental fatigue

Abstract: Mental fatigue is an important aspect of alertness and wellbeing. Existing fatigue tests are subjective and/or time-consuming. Here, we show that smartphone-based gaze is significantly impaired with mental fatigue, and tracks the onset and progression of fatigue. A simple model predicts mental fatigue reliably using just a few minutes of gaze data. These results suggest that smartphone-based gaze could provide a scalable, digital biomarker of mental fatigue.

“…These indicators include, for example, a stimulus proceeding negativity (EEG evoked potential, Moser et al, 2017 ), pupil dilation (Strauss et al, 2016 ; Scheffel et al, 2021 ), the activity of particular brain regions detected in fMRI (e.g., Dörfel et al, 2014 ; Ellard et al, 2017 ), as well as fNIRS studies (Lu et al, 2019 ; Azhari et al, 2020 ), but also subjective self-reports of effort and fatigue (Wong et al, 2017 ; Visser et al, 2018 ). Interestingly, digital biomarkers of mental fatigue, like smartphone-based gaze detection, are also being developed (Tseng et al, 2021 ). Discussed indicators of effort, along with examples of their use and main results, are presented in Table 1 (the table does not aim to provide a systematic review of research on ER effort indicators, rather it describes the most popular and promising indicators and provides examples of their use in previous research on fatigue and effort).…”

“…The questions and possible answers from the FAS are presented in Figure S1 (see Supplemental Material). According to [71], the FAS total score can be classified into three classes: no fatigue (1-21), substantial fatigue (22)(23)(24)(25)(26)(27)(28)(29)(30)(31)(32)(33)(34)(35) and extreme fatigue (36)(37)(38)(39)(40)(41)(42)(43)(44)(45)(46)(47)(48)(49)(50). From the 17 participants, 3 were in the no fatigue class (19 ± 2), 8 in substantial fatigue (27 ± 3), and 6 (37 ± 3) in extreme fatigue.…”

“…Several reports exist in the scientific literature about mental fatigue detection by tracking changes in neural activity through electroencephalography (EEG), which is considered the 'gold standard' for mental fatigue assessment [20]. However, most of these studies present common methodological patterns, including the following: (1) the use of gel-based EEG caps [21][22][23], which require a considerable setup time, proportional to the number of electrodes in the cap; (2) the use of often long (>50 min) fatigue-inducing tests to identify different levels of mental fatigue during model evaluation [20,[23][24][25]; and (3) the construction of predictive models which are highly subject-specific [22,[26][27][28].…”

“…Depression and anxiety are the main disorders in the mental health domain, which are broadly experienced by 548 million people worldwide who hardly access effective treatment [127], [128]. mHealth Sensing gives ubiquitous and flexible solutions on both sides of personal mental health management [129]- [132] and population mental health surveying and understanding [133], [134].…”
