Research On Wood Application Of Spatial Interface Of Pedestrian Street In Cold Region Based On Visual Perception

Pedestrian street space is an important part of urban public space.As a key node of urban environment and image building,its space quality is closely related to the activities and visual perception of crowds.In recent years,the amount of pedestrian street construction has increased significantly.As the main carrier of urban public space,lack of vitality is an urgent problem to be solved.Wood,with its inherent warmth and natural sense,is widely used in the pedestrian street space environment in the cold.In the pedestrian street,seats and other common street furniture,wood compared with other materials can be more favored by the public.The research on the application of wood in the pedestrian street is not enough.This paper aims to explore the visual perception of wood application in the spatial interface of the pedestrian street in the cold region and its design influencing factors,so as to provide a design basis for improving the spatial environment quality of the pedestrian street in the cold region.In this paper,three dimensions of vision,psychology and behavior are evaluated and measured.The experiment is carried out through questionnaire and virtual simulation experiment.The questionnaire is mainly aimed at visual and psychological dimension,while the virtual simulation experiment is aimed at behavioral dimension.This paper explores the visual perception evaluation and its influencing factors of wood application in the side and bottom interfaces of pedestrian street space,and concludes and analyzes its action law and perception mechanism.Firstly,focus group discussion method and case analysis method were used to establish that the application position,application form,wood color and coverage rate of wood were the main influencing factors for the visual perception evaluation of the side interface,and the application form and application spacing of wood were the main influencing factors for the visual perception evaluation of the bottom interface.Then,the types of pedestrian street space and common application modes of wood are summarized and analyzed,the level of each evaluation influencing factor is clarified,and 12 side interface models and 10 bottom interface models are designed by uniform test method.Questionnaires were distributed on the network questionnaire platform.The virtual simulation experiment was conducted with HTC VIVE PRO,a virtual simulation device,based on Unity 3D and Steam VR platform.The questionnaire and virtual simulation experiment data were recovered,and SPSS software was used for data processing.Finally,the design strategy is proposed according to the experimental results.The results show that the wood application position and coverage rate in the side interface are significantly correlated with the visual perception evaluation,and the wood application spacing and application combination form in the bottom interface are significantly correlated with the visual perception evaluation.The wood coverage rate at the side interface is curviline related to the vis ual perception evaluation,and the maximum and minimum values are obtained when the coverage rate is 65% and25% respectively.The application spacing of bottom interface wood is curve related to the audience perception evaluation,and the maximum and mini mum values are obtained at 35 m and 25 m respectively.In this study,wood visual perception research is introduced into outdoor group buildings,which provides new ideas for wood application and pedestrian street design.Based on the experimental results,the application strategies were proposed from three perspectives,namely,the side interface,the bottom interface and the transformation target,in order to provide scientific basis for improving the environmental quality of commercial pedestrian streets through wood application.
