“…The data were obtained in a randomised cross-over study that investigated whether eye-tracking is a feasible measure of workload fluctuation during induction of anaesthesia in a full-scale simulator environment either with or without a critical event. 12 The participants were asked to induce general anaesthesia during three different simulator sessions. To enhance familiarity with the simulator setting, the participants were told that no critical incident would occur during the first session.…”

“…[6][7][8] Moreover, it was applied to measure the effects of intraoperative reading on the anaesthetist's vigilance and workload, 9 and the impact of day and night shifts on anaesthesiological workload. 10 The RPE scale is a global measure taking into account all demands 11 and its scores (6)(7)(8)(9)(10)(11)(12)(13)(14)(15)(16)(17)(18)(19)(20) are reported to correlate closely with actual heart rates (60-200 min À1 ). 5 In the present study, we investigated the validity and test-retest reliability of the RPE scale for the subjective assessment of workload during simulator sessions with and without critical incident.…”

“…For instance, in radiology, the NASA-TLX was used with physiological measures -gross eye and head movementsto investigate the workload imposed by two display options -mammograms on a multi viewer adjacent to workstation and a digital version for soft copy display -on clinical readers to analyse mammograms [45]. A pilot study in an anaesthesia simulator environment, motivated by patient safety, was devoted to test the hypothesis that physiological measures such as heart rate, duration of fixation and pupil size increase, whereas saccade amplitude decreases with increased severity of a simulated critical incident, being induction of general anaesthesia the primary task executed by trainee anaesthetists [44].…”

Abstract-Mental workload is a design concept borrowed from Ergonomics with a significant adoption in the aviation and automobile industries. Nowadays, the consideration of this construct is also taking place in many modern clinical working environments for designing interacting and complex systems that impose ever greater cognitive demand on operators and less physical load. Measuring mental workload is essential for improving the interaction human-system, enhancing performance, reducing the operator's error and increasing safety. However, defining, measuring, assessing mental workload and understanding how this impinges on performance are still open problems. This secondary research is firstly aimed at introducing the construct of mental workload, its foundations, measurements techniques as well as applications in medicine.It then discusses open problems for applied research and eventually, it concludes with a list of challenges for scholars and practitioners. The goal is to provide the reader with a picture of the state of the science of mental workload in medicine and clinical domains with an eye towards future research.

“…In a study of anaesthetists' workload fluctuations during full-scale simulator sessions (Schulz et al, 2011), pupil diameter was used as one of the physiological measures of workload. It is found that pupil diameter and heart rate increased simultaneously as the severity of the simulated critical incident increased.…”

This report summarizes the important research activities, study results and research accomplishments out of the RMCLM project in the past year period. The objective of this project includes research of the fundamental issues related to the use of multiple input modalities and their fusion to enable robust and automatic cognitive load measurement (CLM) in the real world. Firstly, we carried out a further literature review on physiological measures of cognitive workload to include the recent advances of physiological measures of cognitive workload. In the meantime, we examined the use of various features (e.g. spectral and approximate entropies, wavelet-based complexity measures, correlation dimension, Hurst exponent) of electroencephalogram (EEG) signals to evaluate changes in working memory load during the performance of a cognitive task with varying difficulty/load levels. Eye based CLM was also studied. Three types of eye activity were investigated: pupillary response, blink, and eye movement (fixation and saccade). We further investigated the linguistic feature based CLM in this study and analyzed novel linguistic features as potential indices of cognitive load. All together, we had carried out CLM study of three unobtrusive modalities, namely EEG, eye activity, and linguistic feature based CLM, in the past year period.
