Accounting for effects of variation in luminancein pupillometry for field measurements ofcognitive workload
Pignoni, Giovanni; Komandur, Sashidharan; Volden, Frode (Peer reviewed; Journal article, 2020)Eye-tracking is now above and beyond the sole measurement of visual attention. Amongst the multiple measures it provides, some have been explored as a measure of cognitive workload (CW). One such measure is pupil diameter. ... -
Development of a quantitative evaluation tool of cognitive workload in field studies through eye tracking
Pignoni, Giovanni (Master thesis, 2019)Eye tracking is primarily intended as a mean for tracking the visual attention of an observer/operator. Still, eye tracking is also capable of recording a wider variety of psychophysical data, one of these is the trace ... -
