虚拟现实运动病的生理评价方法研究

A Study of Physiological Evaluation Method of Cybersickness

针对运动病生理评价方法实验研究较少的现状,通过单因素重复测量的实验设计方法探究得到一种新的虚拟现实运动病的生理评价方法。研究结果表明,不同的实验情境会显著影响心率指标(P<0.05)与皮电指标(P<0.05),非虚拟现实因素会显著影响皮电指标(P<0.05);心率适宜作为评价虚拟现实运动病的生理指标而皮电与呼吸频率不适宜,且患者的心率在其产生症状后会显著增加;心率、呼吸频率、皮电均无法评价虚拟现实运动病的病状程度。

A new physiological evaluation method of cybersickness was developed through one-way repeated measuresdesign ANOVA method for the lack of experimental research on physiological evaluation method of motion sickness.Experimental results suggested that 1） the effect of different experimental situations on heart rate（P〈0.05） and skinconductance （P〈0.05） was significant, 2） the effect of non-virtual reality factors on skin conductance was significant（P〈0.05）. Heart rate is appropriate as a physiological index to evaluate cybersickness and will significantly increase whenbecoming symptomatic, while skin conductance and respiration rate are not. Besides, all the three physiological indexes arenot appropriate to evaluate the degree of cybersickness.
