摘要: This study was carried out to evaluate a method used measure three-dimensional (3D) cognitive fatigue based on the pupillary response. technique designed overcome measurement burdens by using non-contact methods. The response is related function neural pathway and may be an indicator of 3D fatigue. Twenty-six undergraduate students (including 14 women) watched both 2D versions video for 70 min. participants experienced visual after viewing content. Measures such as subjective rating, time, event-related potential latency, heartbeat-evoked (HEP) alpha power, task-evoked (TEPR) latency were significantly different. Multitrait-multimethod matrix analysis indicated that HEP TEPR measures had stronger reliability higher correlations with than other measures. useful quantitatively determining fatigue, it can easily without measuring burden.
