Approximation of on-line mental workload index in ATC simulated multitasks

A neuroergonomic approach to evaluating mental workload in hypermedia interactions

“…The results did not confirm our previous findings on the dynamic of saccadic movement (Di Stasi et al, 2010a,b, 2011. This index has been investigated in dynamic and complex tasks, such as a riding/driving simulation (Di Stasi et al, 2009, submitted for publication), and was found to be highly sensitivity to variation in mental state (MW and fatigue).…”

Towards testing auditory–vocal interfaces and detecting distraction while driving: A comparison of eye-movement measures in the assessment of cognitive workload

“…However, we attempted to control reactions to this environment with dedicated questionnaires. Moreover, due to the low sampling rate of our eye-tracker (30 Hz), we have not analyzed one sensitive measure of operator's cognitive workload, which is the peak velocity of saccadic main sequence (Di Stasi, Marchitto, Antolí, Baccino, & Cañas, 2010). Future studies can also pay more attention to combining different methods of driver-state monitoring (e.g., physiological and vehicle performance variables) in order to build more valid in-vehicle systems.…”

Investigation of Nonlinear Pupil Dynamics by Recurrence Quantification Analysis

“…A simple and noninvasive method is proposed. Sophisticated systems are available for the investigation of pupil dynamics [35]: high resolution cameras (about 1 megapixels) with around 0.5–1 kHz of sampling frequency even allow for the accurate investigation of microsaccadic movements [36]. The pupillogram is here investigated using a low cost recording system (less than 5.000 euro versus up to 40.000 euro needed for sophisticated devices [37]).…”
