本文讨论的是驾驶模拟，特别是关于晕动病的重要问题。针对静态模拟器和动态模拟器，提出了一种由运动病剂量值和问卷推导出的客观疾病分级指标的评价方法。在运动平台激活和不激活的情况下，记录受试者前庭信号（头部运动）的加速度。为了比较两种情况下的用户体验，根据获得的加速度和晕动病剂量值计算出与头部动力学相关的疾病等级。主观分析方面，采用主成分分析法确定静态条件下主观评价与动态条件下主观评价的冲突。主观评价的主成分分析方法显示，静态平台病例与动态平台病例的疾病问卷答案差异一致。双尾Mann-Whitney U检验显示了个体问题的自我报告之间差异的显著性。根据双尾Mann-Whitney U检验，从静态组到动态组，恶心（p = 0.019 < 0.05）和头晕（p = 0.018 < 0.05）明显减少。静态组和动态组的眼疲劳（p = 0.047 < 0.05）和疲劳（p = 0.047 < 0.05）均显著降低。对于感知保真度分析，采用置信区间为95%的Pearson相关来研究每个问题与x疾病评级成分IRx、y疾病评级成分IRy、z疾病评级成分IRz和复合疾病评级IRtot的相关性。结果表明：纵向头部运动是引起静态平台不适感的主要因素，而垂直头部运动是引起动态平台不适感的主要因素。此外，对于动态平台，横向前庭水平的动态是引起恐惧感的主要因素。
This paper deals with driving simulation and in particular with the important issue of motion sickness. The paper proposes a methodology to evaluate the objective illness rating metrics deduced from the motion sickness dose value and questionnaires for both a static simulator and a dynamic simulator. Accelerations of the vestibular cues (head movements) of the subjects were recorded with and without motion platform activation. In order to compare user experiences in both cases, the head-dynamics-related illness ratings were computed from the obtained accelerations and the motion sickness dose values. For the subjective analysis, the principal component analysis method was used to determine the conflict between the subjective assessment in the static condition and that in the dynamic condition. The principal component analysis method used for the subjective evaluation showed a consistent difference between the answers given in the sickness questionnaire for the static platform case from those for the dynamic platform case. The two-tailed Mann-Whitney U test shows the significance in the differences between the self-reports to the individual questions. According to the two-tailed Mann-Whitney U test, experiencing nausea (p = 0.019 < 0.05) and dizziness (p = 0.018 < 0.05) decreased significantly from the static case to the dynamic case. Also, eye strain (p = 0.047 < 0.05) and tiredness (p = 0.047 < 0.05) were reduced significantly from the static case to the dynamic case. For the perception fidelity analysis, the Pearson correlation with a confidence interval of 95% was used to study the correlations of each question with the x illness rating component IRx, the y illness rating component IRy, the z illness rating component IRz and the compound illness rating IRtot. The results showed that the longitudinal head dynamics were the main element that induced discomfort for the static platform, whereas vertical head movements were the main factor to provoke discomfort for the dynamic platform case. Also, for the dynamic platform, lateral vestibular-level dynamics were the major element which caused a feeling of fear.
