Abstract:
Provided are a method and system for noncontact vision-based 3D cognitive fatigue measuring. The method comprises: acquiring pupil images of a subject exposed to visual stimuli; extracting a task evoked pupillary response (TEPR) by using the pupil images; detecting dominant peaks from the TEPR; calculating latency of dominant peaks; and determining cognitive fatigue of the subject by comparing a value of the latency to a predetermined reference value.
