Research On Street Spatial Perception Based On Visual Behavior Experiment

With the in-depth development of humanism in various research fields,the design evaluation research of street space has gradually formed a focus shift from the object material space to the subjective spatial perception of people,and the combination of scientific and technological progress and interdisciplinary research has provided the impetus for this shift.As the subject of space use,people’s behavior perception in space is taken as the starting point for analysis.The bottom-up analysis method helps researchers in related fields to grasp the evaluation feedback from actual users and provides an objective basis for the fine research of street space.This paper selects the historical road of longtou road in gulangyu island as the research object and classifies the historical road space by cluster analysis.Then the visual perception data of all kinds of historical road space were collected by combining the eye movement experiment and SD method.Based on the analysis of eye movement thermal map and focus map,one-way analysis of variance,factor analysis and correlation analysis,the visual perception of historical road space is studied,and relevant strategies and suggestions are put forward.The research shows that among the three types of historical road space in longtou road,the street space elements that the subjects mainly pay attention to can be divided into 9 categories,among which the perspective focus,green landscape,architectural elements and signboard advertisement have higher visual attraction to the subjects.Through the analysis of eye movement data,each historical road can be evaluated from visual attraction factors and visual search factors.The results show that the street space of study sample 4,study sample 5 and study sample 10 has high visual attraction.In terms of subjective perception,the subjective perception characteristics of all kinds of historical road space can be obtained by SD method,and further subjective perception evaluation can be made by means of psychological perception factors of street space,perception factors of street space scale and commercial perception factors of street space.Finally,through the correlation analysis of visual behavior evaluation and subjective feeling,the visual perception of each historical road space is further revealed,and it is found that there is a significant positive correlation between the visual attraction factor and the psychological perception factor of street space,which indicates the objectivity and effectiveness of eye movement analysis applied to the study of street space perception.This study from the perspective of human-oriented study of street space objects,to explore the eye movement analysis techniques in combination with the practice of subjective perception questionnaire in the historical road space use,the protection and development of the gulangyu island history provides a theoretical and technical support,and expand the research train of thought,and for the future can be used as a reference for related research in the field of play.
