摘要
以审美体验为核心的环境感受一直是国内外风景园林领域的核心问题,但其测量却比较困难。介绍了一种依靠可穿戴生物传感器进行实景环境实时情绪感受评价的新方法。在国际相关实验技术的基础上,依靠实验方法通过心电传感器(EKG/ECG)、脑电传感器(EEG)、皱眉肌肌电传感器(EMG)、皮温传感器(ST)、皮电传感器(SC)和呼吸传感器(resp),记录实时环境行走中的人的情绪体验。数据在matlab里面经降噪、伪迹去除、时频分析、生成采样率为1帧每秒的情绪评价值,再与GPS空间位置做数据融合,生成具有空间属性的情绪评价轨迹。研究发现,结合时空间轨迹的生理情绪数据较好地反映了被试受空间影响的情绪反应,传感器采集的情绪结果与现场试验后访谈中实验者表达的环境体验结果吻合较好。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并理解环境体验,为未来设计提供诸多可能。
Environmental experience centered in aesthetics is a vital issue to landscape architecture both in China and globally.However,the measurement of experience is difficult.This paper presents a new method of assessing real-time in-situ environmental affective experience via wearable bio-sensory techniques.Built on existing experimental techniques and findings,the authors designed experiment to calculate environmental affective experience during real-time walking via electrocardiogram(EKG/ECG),electroencephalogram(EEG),corrugator electromyogram(EMG),skin temperature(ST),skin conductance(SC)and respiration(resp.)sensors.Signals were processed via denoising,artifact removal,time-domain and frequency-domain analysis before compressed into affective parameters sampled per 1s.The affective parameters were then combined with GPS location data via data fusion into geo-referenced routes with affective assessment.Results indicate that geo-referenced affective assessment revealed results consistent with that collected via interviews after walk.Affective experience measurement technique via wearable sensors would improve measurement accuracy and understanding of environmental affective responses,which would expand the possibilities for future design.
