模拟航天器睡眠舱色彩环境对乘员情绪的影响研究

Effect of Color Environment in Simulated Spacecraft Sleeping Capsule on Crew Emotion

目的 研究不同情绪刺激下睡眠舱色彩环境对乘员情绪的影响规律。方法 对30名受试者(男15人、女15人)分别进行了中性、负性2种VR情绪影片的情绪诱发,之后在VR环境中进行模拟睡眠舱色彩环境体验,完成主观情绪评价,同时采集受试者在色彩环境中体验时的20通道脑电信号;对主观情绪评价进行方差分析,并对脑电信号进行预处理,分析α、β频带的脑电信号能量。结果 主观情绪评价显示,在色彩环境舒适度上,不同色彩环境(冷色、暖色、无彩色)呈现显著性差异(P=0.000<0.05);在情绪缓解度上,不同色彩环境(冷色、暖色、无彩色)呈现显著性差异(P=0.000<0.05)。脑电信号显示,冷色环境下额叶区和顶叶区的α波左右脑叶平均功率比值最低,而暖色环境最高;冷色环境下颞叶区的β波左右脑叶平均功率比值最低,而暖色环境最高。结论 在狭小、密闭的模拟航天器睡眠舱环境下,色彩环境对于受试者的情绪调节作用在生理状态和心理感受上都能得到显现,并且其主观感受和客观生理数据分析结果在一定程度上能够达到拟合。其中蓝色环境、绿色环境、白色环境主客观值表征的情绪状态最好,更能有效改善和形成良好的情绪状态。最后经模拟航天器睡眠舱色彩设计实践,验证了航天器睡眠舱色彩设计优化策略的可行性及可靠性。

The work aims to study the effect of color environment in sleeping capsule on crew emotion under different emotional stimuli.30 subjects(15 men and 15 women) were respectively induced by neutral and negative VR emotional films,and then experienced the color environment of the simulated sleeping capsule by VR technology to complete the subjective emotional evaluation.20 channel EEG signals of subjects experiencing the color environment were collected.Variance analysis was carried out on subjective emotion evaluation,and EEG signals were preprocessed to analyze the EEG signal energy of α and β frequency bands.Subjective emotional evaluation showed that:in terms of color environment comfort,different color environments(cold color,warm color,colorless) showed significant differences(p=0.0000.05);and in terms of emotional relief,different color environments(cold color,warm color,colorless) showed significant differences(p=0.0000.05).EEG signal displayed:The average power ratio of left and right lobe of inferior frontal lobe and parietal lobe under α wave was the lowest in cold color environment,and the highest in warm color environment.The average power ratio of left lobe and right lobe in inferior frontal lobe under β wave was the lowest in cold color environment and the highest in warm color environment.In the narrow and closed simulated spacecraft sleeping capsule environment,the emotional regulation of the color environment on the subjects can be reflected in their physiological state and psychological feelings,and their subjective feelings and objective physiological data analysis results can be fitted to a certain extent.Among them,the subjective and objective values of blue environment,green environment and white environment are the best,which can effectively improve and form a good emotional state.Finally,the feasibility and reliability of the optimization strategy for the color design of the spacecraft sleeping capsule are verified through the simulation of the color design practice of the spacecraft sleeping capsule.
