Physical Appearance Design Evaluation of Community Emotional Healing Installations Based on Analytic Hierarchy Process–Fuzzy Comprehensive Evaluation Method

An increasing number of residents are burdened with psychological pressure, and the majority of them refuse to seek professional mental help, falling to a “silent majority” of the untreated. This “silent majority” lives in every corner of cities, and public installations scattered in various spaces have the potential to become community emotional healing touchpoints. Therefore, it is urgent to establish a comprehensive evaluation system for emotional healing installations. This research establishes a physical appearance evaluation system for healing installations based on affinity analysis, thereby combining the Analytic Hierarchy Process (AHP) and Fuzzy Comprehensive Evaluation (FCE) to construct data matrixes and quantitative analysis. The AHP results revealed some trends, including that placing environment is the most critical design indicator for healing installations, saturation is more closely associated with healing than color temperature, and small-scale installations have better healing efficacy. FCE ranked the combined weights of design indicators and revealed preference differences between Western and Eastern scholars regarding emotional healing. Eastern scholars show a clear preference for low-saturation colors and place significant emphasis on the multifunctionality of healing installations. Meanwhile, Western scholars have a stronger inclination toward healing shapes. Furthermore, this research conducts cross-category analysis and sensitive analysis to provide rigorous foundations for future healing research and offer guidance to future designers in healing installation design.
