界面透明度与店面密度是提高街道空间活力的两个设计要素,也是与视觉感知密切相关的主要因素.调研沈阳市8条商业街,总结提炼典型寒地生活性街道空间场景要素.按照“空间—感知”研究模型,对4 种界面透明度以及一种透明度定值下的 4 种店面密度进行计算机场景建模,令被试者观看场景模拟视频,同步应用人因设备将心率变异性(HRV)、皮肤电(EDA)与主观评价进行感知测度量化分析,推演了视觉感知舒适状态下商业街底层临街面设计要素的量值.研究结果表明,当街道界面透明度为40%时人的视觉感知舒适度最高,店面密度为15个/100 m时人的视觉感知舒适度最好.本文探讨了一种主观与客观结合的“空间—感知”量化研究方法,研究人的视觉感知与街道空间中的界面透明度、店面密度之间的关系,对今后商业街底层临街面的感知舒适研究与设计实践具有一定借鉴意义.

Interface transparency and storefront density are two elements that enhance the vitality of street space design, and are also closely related to visual perception. Based on the investigation of 8 commercial streets in Shenyang, the elements of typical cold area living street space scenes were summarized and refined. In accordance with the “space-perception” research model, On the basis of setting up the scene model, the subjects watched the scene simulation videoThen,using human factors equipment to quantitatively analyze three kinds of information: heart rate variability(HRV), electrodermal activity(EDA)and subjective evaluation. The value of the design elements of the ground floor interface in the commercial street under the condition of visual perception comfort is discussed. Finally, the research results show that when the transparency of the street interface is 40%, people's visual perception comfort is the highest, when the storefront density is 15 per 100 m, people's visual perception comfort is the best. By simulating the street space scene, applying physiological sensors to extract people's perceived physiological indicators, and combining subjective questionnaires to conduct “space-perception” research, this paper analyzes the relationship between people's visual perception, interface transparency, and storefront density. The research and design practice of the perceived comfort in the ground floor interface has certain reference significance.
