This study was carried out to evaluate a method used to measure three-dimensional (3D) cognitive fatigue based on the pupillary response. This technique was designed to overcome measurement burdens by using non-contact methods. The pupillary response is related to cognitive function by a neural pathway and may be an indicator of 3D cognitive fatigue. Twenty-six undergraduate students (including 14 women) watched both 2D and 3D versions of a video for 70 min. The participants experienced visual fatigue after viewing the 3D content. Measures such as subjective rating, response time, event-related potential latency, heartbeat-evoked potential (HEP) alpha power, and task-evoked pupillary response (TEPR) latency were significantly different. Multitrait-multimethod matrix analysis indicated that HEP and TEPR latency measures had stronger reliability and higher correlations with 3D cognitive fatigue than other measures. TEPR latency may be useful for quantitatively determining 3D visual fatigue, as it can be easily used to evaluate 3D visual fatigue using a non-contact method without measuring burden.
本研究旨在评估一种基于瞳孔反应测量三维（3D）认知疲劳的方法。该技术旨在通过使用非接触方法来克服测量负担。瞳孔反应通过神经通路与认知功能相关，可能是3D认知疲劳的一个指标。26名本科生（包括14名女性）观看了一个视频的2D和3D版本各70分钟。参与者在观看3D内容后经历了视觉疲劳。主观评分、反应时间、事件相关电位潜伏期、心跳诱发电位（HEP）α功率和任务诱发瞳孔反应（TEPR）潜伏期等测量结果存在显著差异。多特质多方法矩阵分析表明，与其他测量方法相比，HEP和TEPR潜伏期测量具有更强的可靠性，并且与3D认知疲劳的相关性更高。TEPR潜伏期可能有助于定量确定3D视觉疲劳，因为它可以通过非接触方法轻松用于评估3D视觉疲劳，而无需测量负担。
