Construction of an Ethical Monitoring System for Public Space Design Based on Quantitative Models

Digital technologies profoundly reshape the ethical order of public spaces through algorithmic recommendations, behavioral guidance, and perceptual manipulation. This research proposes a “critical experience analysis” methodological framework, establishing the “Dynamic Autonomy Erosion Index (DAEI),” “Technological Colonization of Spatial Sovereignty Index (TCSI),” and “Public Deterioration Threshold Model (PDTM)” to form a digital ethics spatial monitoring system. The system integrates heat map tracking, affective computing, and machine learning technologies to quantitatively analyze the implicit control of technology over public spaces. This research provides a “theoretical deconstruction-empirical monitoring-critical warning” full-chain solution for spatial governance in the digital era, promoting the transition of technological ethics from philosophical critique to quantifiable intervention.
