本文的目的是利用小波变换对航海员出发或到达时的心率变异性进行分析，并利用心率变异性的生理指标来处理实际船舶和船舶驾驶台模拟器之间的差异。利用频率分量范围计算交感神经系统(SNS)和副交感神经系统(PNS)。由于我们认为航海员心理负担的影响在每一种情况下都还不清楚，即心理负担的种类或强度尚不清楚，而且模拟器对船舶或航海仪器的训练也做得很好，我们需要从人的感觉的角度来了解这种影响。因此，我们提出了一种方法，通过使用离开或到达之间的SNS与SNS平均值的比率来寻找评估精神负担的指标。结果表明，该指标是有效的。
The purpose of this paper is to analyse heart rate variability of a navigator at departure or arrival by the wavelet transform and we tackle the difference between an actual ship and ship's bridge simulator by utilizing a physiological index of heart rate variability. SNS (sympathetic nervous system) and PNS (parasympathetic nervous system) is calculated by using the frequency component range. Because we think that the influence of the mental burden of the navigator is not clear yet in each case, in other words, the kind or strength of their mental burden is not clear and also training of ship or navigational instrument handling by simulator does very well, we need to know the effect from the standpoint of human sensation. So we propose a method of finding an index of assessment of the mental burden by using a ratio of SNS to average of SNS among departure or arrival. The results show that this index was effective.
