精神疲劳测量技术利用一个或组合的认知,情感,和身体的行为反应。眼动追踪和眼电图,用于计算基于眼睛的特征,随着市场中出现的轻型设备的准确性和鲁棒性的提高,已经获得了动力,可用于客观和连续评估精神疲劳。本系统综述的主要目的是总结用于测量精神疲劳的各种基于眼睛的特征,并探讨基于眼睛的特征与精神疲劳的关系。审查过程,在系统评价和荟萃分析的首选报告项目之后,使用了WebofScience的电子数据库,Scopus,ACM数字图书馆,IEEEXplore,和PubMed。在检索到的1385份文件中,34项研究符合纳入标准,产生21个有用的基于眼睛的特征。将这些分为八组,显示扫视是最有前途的类别,扫视平均和峰值速度可在疲劳活动的30分钟内快速访问认知状态。涉及交感神经和副交感神经系统的复杂大脑网络控制精神疲劳与强直性瞳孔大小的关系,并有可能在受控的实验条件下表明精神疲劳。其他类别,像眨眼一样,来自睡眠研究领域,应谨慎使用。分析中出现了几个局限性,包括各种实验方法,在实验过程中使用昏暗的照明(这可能也会引起嗜睡),使用不清楚的数据分析技术,从而使研究之间的比较变得复杂。
Mental fatigue measurement techniques utilize one or a combination of the cognitive, affective, and behavioral responses of the body. Eye-tracking and
electrooculography, which are used to compute eye-based features, have gained momentum with increases in accuracy and robustness of the lightweight equipment emerging in the markets and can be used for objective and continuous assessment of mental fatigue. The main goal of this systematic
review was to summarize the various eye-based features that have been used to measure mental fatigue and explore the relation of eye-based features to mental fatigue. The
review process, following the preferred reporting items for systematic reviews and meta-analyses, used the electronic databases Web of Science, Scopus, ACM digital library, IEEE Xplore, and PubMed. Of the 1,385 retrieved documents, 34 studies met the inclusion criteria, resulting in 21 useful eye-based features. Categorizing these into eight groups revealed saccades as the most promising category, with saccade mean and peak velocity providing quick access to the cognitive states within 30 min of fatiguing activity. Complex brain networks involving sympathetic and parasympathetic nervous systems control the relation of mental fatigue to tonic pupil size and have the potential to indicate mental fatigue in controlled experimental conditions. Other categories, like blinks, are derived from the field of sleep research and should be used with caution. Several limitations emerged in the analysis, including varied experimental methods, use of dim lighting during the experiment (that could possibly also induce sleepiness), and use of unclear data analysis techniques, thereby complicating comparisons between studies.
