| 摘要: |
| 目的 探究在座椅舒适性评价中，皮电反射（Electrodermal Activity，EDA）、心率变异性（Heart Rate Variability，HRV）以及瞳孔直径等数据是否与用户主观舒适性存在显著关联关系。方法 通过设计实验，自变量为两种不同的座椅，因变量为EDA、HRV、瞳孔直径以及用户对于座椅舒适性的主观评价，使用SPSS统计分析软件对实验数据做独立样本t检测等，分析其相关性。结果 就坐于两种不同座椅的被试瞳孔直径变化存在差异性显著（方差齐，t0.05(27)=–2.718，p<0.05），其皮电反射EDA与心率变异HRV的检测结果为差异性不显著。结论 在基于心理生理测量方法的座椅舒适性评价研究中，瞳孔指标相对敏感，且与主观评价相关性强，一定条件下可以使用瞳孔数据协同优化座椅舒适度评价；暂无充分证据支持皮电反射和心率变异性与座椅舒适性存在显著关联。此外，应用眼动追踪等心理生理测量方法，可以在一定程度上反向指导座椅的改良与设计。 |

| Abstract: |
| The work aims to study whether EDA (electrodermal activity), HRV (heart rate variability), pupil diameter and other statistics have a notable correlation on user subjective comfort during the seat comfort evaluation. Through designing experiments, the independent variables were two different seats, and the dependent variables were EDA, HRV, pupil diameter and the user's subjective evaluation of seat comfort. SPSS statistical analysis software was used to conduct independent sample t-test on experimental data and analyze the correlation. There was significant difference in pupil diameter between the two groups of subjects sitting in different types of seats (variance of the two samples was equal, t0.05(27)=–2.718,p<0.05), and no significant difference was found in the results of skin electrical reflex and heart rate variation. In the study of seat comfort evaluation based on psycho-physiological measurement method, the pupil index is relatively sensitive and highly correlated with subjective evaluation. Under certain conditions, the pupil data can be used to cooperatively optimize seat comfort evaluation. There is no sufficient evidence to support that there is a significant correlation between skin reflexes and heart rate variability and seat comfort. In addition, the application of eye tracking and other psycho-physiological measurement methods can reverse guide the improvement and design of seats to a certain extent. |
