OBJECTIVE
The aim of this study is to evaluate the effectiveness of a seat-integrated mobilization system for maintaining vigilance under monotonous driving situations.
METHOD
For this purpose, vigilance indicators were compared intra-individually in a test condition with mobilization (seat-integrated stimulation) and a placebo condition under standardized conditions in a real driving study (N = 31). During a monotonous two-hour ride, physiological (brain activity by the EEG alpha spindle rate), performance-based (reaction times) and subjective indicators were recorded.
RESULTS
The necessary precondition for the paradigm of inducing fatigue through monotony was confirmed by a significant increase in the EEG alpha spindle rate and the subjective vigilance indices. The mobilization system had a significant impact on the most fatigue-sensitive parameter of the alpha spindle rate, whereas the other parameters of vigilance did not reflect a significant effect of mobilization.
CONCLUSION
The Mobilization Seat is an effective measure to prevent drivers' fatigue during monotonous situations.
目的
本研究旨在评估座椅集成式动员系统在单调驾驶情况下保持警觉的效果。
方法
为此，在一项实际驾驶研究（N=31）中，在标准化条件下，通过个体内比较，在动员（座椅集成刺激）和安慰剂条件下测试警觉指标。在单调的两小时车程中，记录了生理（EEG 阿尔法纺锤波率的大脑活动）、基于表现（反应时间）和主观指标。
结果
通过单调诱导疲劳的范式的必要前提条件通过 EEG 阿尔法纺锤波率的显著增加以及主观警觉指标得到了证实。动员系统对阿尔法纺锤波率最敏感的疲劳参数有显著影响，而警觉的其他参数则没有反映出动员的显著效果。
结论
动员座椅是预防驾驶员在单调情况下疲劳的有效措施。
