摘　　要：城市光环境对人的生理和心理均能产生显著影响,但如何科学地量化评估却较为困难。神经生物学及可穿戴生理传感器技术的成熟化为量化人员对实验室研究光环境的身心体验提供了理论基础和技术支持。本文介绍了在复杂的真实城市场景中,基于可穿戴设备获取生理反馈数据,进行光环境对情绪影响的探索性实验研究。研究以上海南京东路步行街为实验场所,实时监测人员在四类不同光照模式景观场景下的面部表情、皮电、皮温以及心电生理指标,通过筛检与分析探讨其中的阈值差异,并使用主观问卷对生理指标结果进行验证。研究发现,皮温、皮电、面部表情以及主观量表结果均显示出了日、夜景观光环境感知的显著差异。在夜间模式的对比中,皮电信号显示被试在闪烁模式下的情绪唤醒值显著高于全黑模式;主观量表结果表明被试在全黑模式下的情绪效价最低,而面部表情结果显示被试在全黑模式下的情绪效价显著高于点亮模式;皮温和心电信号并未在三类夜间模式下反馈出有效差异。基于可穿戴传感器的情绪体验测量技术,将有助于更好地测量及理解城市夜空间的环境体验,为未来城市景观照明设计提供更有效的理论指导。Light environment can have a significant impact on people’s physiology and psychology, but it is difficult to evaluate scientifically and quantitatively. The maturity of neurobiology and wearable physiological sensor technology provides theoretical basis and technical support for quantifying personnel’s physical and mental experience of light environment in laboratory research. This paper introduces an exploratory experimental study on the impact of light environment on emotion based on wearable devices to obtain physiological feedback data in complex real city scenes. Taking the East Nanjing Road Pedestrian Street in Shanghai as the experimental site, this study monitored the facial expression, skin conductance, skin temperature and ECG data under four different landscape lighting scenes in real time. The threshold differences were discussed through screening and analysis. Finally, the results of physiological indexes were verified by questionnaire. The study found that skin temperature, skin conductance, facial expression and subjective scale showed significant differences in the subjects’ perception in day and night scenes. In the contrast of three night modes, the skin conductance shows that the value of arousal in flashing mode was significantly higher than that in dark mode;The subjective scale results showed that the emotional potency of the subjects in the dark mode was the lowest, while the facial expression results showed that the emotional potency of the subjects in the dark mode was significantly higher than that in the lit mode;however skin temperature and ECG signals did not show any effective differences among the three night modes. The emotional experience measurement technology based on wearable sensors will help to measure and understand the environmental experience of urban night space, and provide more effective theoretical guidance for urban landscape lighting design in the future.
