| Abstract |
Evaluations of urban public spaces tend to focus on physical form shortly after completion and do not adequately account for experiences that develop through repeated use. This study defines the Subtle effect as a subtle, delayed effect through which initially backgrounded spatial cues acquire meaning through repeated experience. It draws on an integrative review of the literature on phenomenological theories of space, affordance theory, environmental psychology, and post-occupancy evaluation, together with illustrative interpretations of Seoul Citizens Hall, Busan Citizens Park, and the Seoul Hall of Urbanism & Architecture. On this basis, the study proposes a moving perceptual threshold model linking the backgrounding of spatial cues (S1), the emergence of meaning (S2), and the structuring of everyday routines (S3). It also identifies four interpretive categories: delayed recognition, the discovery of affordances, embodied familiarity with routes, and place attachment. The proposed framework provides a conceptual foundation for future empirical research and does not constitute an empirically validated finding. |
