The Coupling Relationship Between Street View Element Comfort Perception and Eye Movement Metrics and Its Sustainable Research

People’s perception of the comfort level of street landscape elements is influenced by the built environment, and improving the quality of street landscape environment is of great significance for promoting the sustainable development of cities. This study focuses on 12 sample streets in Zibo City. After obtaining panoramic images of the area through the OSM platform, the FCN framework was used for semantic segmentation. A combination of subjective and objective methods was adopted, and eye tracking indicators were collected using the D-Lab wearable eye tracker. At the same time, a questionnaire quantitative analysis was conducted to systematically investigate the impact mechanism of the combination characteristics of street elements on comfort perception preferences. Research has found that there is a significant correlation between the perceived comfort preference of street scenes and GVI, and the increase in total gaze time towards green elements also shows a significant improvement in perceived comfort preference. After entering the street interface, observers show a high degree of priority attention to street view elements such as building facades and advertising facilities. As the gaze time on the sky (a street view element) increases, people’s perceived comfort evaluation shows a downward trend. There are significant differences in the structural characteristics of different streets, and their impact on improving comfort also varies to some extent. This study links the comfort perception of street landscape elements with sustainable urban development planning. By reasonably allocating landscape elements such as green visibility, basic roads, building interfaces, and signage facilities, it provides certain reference suggestions for the sustainable development of urban street space and human-centered urban construction.
