目的:探讨职场员工处于沉浸式虚拟自然环境后情绪优化的效果。方法:于2020年7月，选取15名受试者分别在虚拟自然环境和日常环境下完成两组跑步机步行训练试验，采集被试步行前后的皮肤电（EDA）、脉搏频率（Pf）、呼吸频率（Rf）及《自我情绪评定量表》（SAM）数据；计算SAM 3个维度的均值以及试验前后的情绪差值，受试者生理指标和主观情绪变化的差异性用配对样本n t检验进行分析。n 结果:与日常环境比较，受试者处于虚拟自然环境后的ΔEDA、ΔPf和ΔRf均降低，差异均有统计学意义（n P<0.05）；受试者使用虚拟自然环境前后愉悦度和唤醒度的差异均有统计学意义（n P<0.05）。与日常环境比较，受试者使用虚拟自然环境后的Δ愉悦度升高，Δ唤醒度和Δ优势度降低，差异均有统计学意义（n P<0.05）。n 结论:虚拟自然环境下步行有助于受试者改善情绪、放松心情、提高自主神经系统的调控能力。“,”Objective:To explore the effect of emotional optimization of workplace employees in immersive virtual natural environment.Methods:In July 2020, 15 subjects were selected to complete two groups of treadmill walking training experiments in virtual natural environment and daily environment respectively. At the same time, the subjects\' skin electrical (EDA) , pulse frequency (Pf) , respiratory frequency (Rf) physiological data and Self-Assessment Manikin (SAM) data before and after walking were collected; the mean value of three dimensions of SAM and the emotion difference before and after the experiment were calculated. The differences of physiological indexes and subjective mood changes of subjects were tested by paired samplen t-test.n Results:Compared with the daily environment, the ΔEDA, ΔPf and ΔRf of the subjects in the virtual natural environment were all decreased , and the differences were statistically significant ( n P<0.05). There were statistically significant differences in pleasure and arousal between subjects before and after using the virtual natural environment (n P <0.05). Compared with the daily environment, the Δpleasure degree of subjects using the virtual natural environment increased, and the Δarousal degree and Δdominance degree decreased, and the differences were statistically significant ( n P <0.05).n Conclusion:Walking in virtual natural environment can help subjects improve their mood, relax and improve the regulation ability of autonomic nervous system.
