On the potential for wearable technology in the modeling of vigilance and fatigue for aeronautic applications

飞行员经常执行安全关键任务，需要高度的警觉性和执行控制。疲劳及其对性能的负面影响已被广泛认为对航空安全构成严重威胁。因此，世界各地正在制定法规，以确保航空公司实施疲劳风险管理系统。泰勒斯研究与技术（TRT）加拿大（魁北克）的科学家们一直在研究这样一个系统，该系统使用可穿戴技术收集生理和性能数据，以评估疲劳相关参数。开发这一能力将为泰雷兹打开一个新的商业市场，并增强其现有的产品线。为了成功地将这种新功能商业化，Thales需要第三方研究人员的帮助来测量和评估生理参数与疲劳引起的性能影响的相关性。因此，他们招募了Klein博士和他的大学实验室，以确定他们正在开发的系统是否可以测量疲劳并准确预测其对表现的负面影响。克莱因实验室招募的人类参与者将通过长时间持续执行精心挑选的认知任务来实验疲劳。在每8小时的会议上，将评估这些任务的表现，填写疲劳的主观报告，并定期收集警戒性疲劳的测量值，同时监测生理参数。克莱因的团队将与泰勒斯团队合作，开发一种数学模型，根据生理参数预测疲劳程度和性能下降。

Pilots regularly perform safety-critical tasks that require a high level of alertness and executive control. Fatigueand its negative effects on performance has been widely recognized as posing a serious risk to aviation safety.Consequently, regulations around the world are being put into place to ensure that the airliners implementfatigue risk management systems. Scientists at Thales Research & Technology (TRT) Canada (Quebec) havebeen working on such a system that collects physiological and performance data using wearable technologies toassess fatigue related parameters. Developing this capability will open a new commercial market to Thales andenhance their existing product lines. To successfully commercialize this new capability Thales requires theassistance of a third party researcher to measure and assess the correlation of physiological parameters withfatigure-induced performance impacts. Consequently, they recruited Dr. Klein and his university-basedlaboratory to determine whether the system they are developing can measure fatigue and accurately anticipateits negative consequences for performance. Human participants recruited to the Klein lab will experimentinduced fatigue by long, continued performance on carefully selected cognitive tasks. Over each 8 hour sessionperformance on these tasks will be assessed, subjective reports of fatigue filled out, and measures of vigilancedecrement will be regularly collected, concurrently to the monitoring of physiological parameters. Workingwith the Thales team, Klein's team will develop a mathematical model that predicts fatigue levels andperformance decrements from the physiological parameters.
