This study aims to scientifically assess the impact of street space design on the psychological healing effect of users. Using Electroencephalography (EEG) and eye tracking technology, we focus on two core design elements, street interface type and green ratings, and use physiological indicators to quantify the healing response of users. Experimental results show that street interface type and green ratings (i.e., the proportion of green plants in the field of view) are two key factors influencing the healing properties of the street, and analysis of the EEG data reveals that street scenes under open space interface and high green ratings conditions have a better healing effect on the subjects because the former reduces the cognitive load, and the latter provides positive stimulation from natural elements. Eye-tracking data revealed the distribution of subjects' visual attention to different street scenes, and it was found that green ratings may have a greater influence on the healing effect than the type of street interface, probably because green ratings directly determines the richness of natural elements, which in turn has a more significant effect on the psyche. The subjective questionnaire, on the other hand, emphasized the importance of the dimensions of being away and extent in the study of street healing, suggesting that street design should focus on providing differentiation from everyday life and spatial expansiveness. The experimental results not only establish the validity of EEG and eye-tracking techniques in the assessment of street space healing, but also propose a scientific evaluation framework that integrates users' physiological and emotional responses. The proposed methodology provides an empirical basis for the improvement and optimization of the healing design of street spaces and enhances the relevance and effectiveness of design interventions.
