The study investigates the role of ambiguous spaces in facilitating social interactions within tropical university campuses, using Hainan University as a case study. Drawing on environmental psychology and spatial theory, the research analyzes interactive behaviors—categorized as necessary, optional, and social activities—and examines how individual spatial preferences (peripheral orientation), group spatial dynamics (central clustering), and boundary perception influence behavioral patterns. The study clarifies the theoretical foundation of ambiguous spaces, tracing their origins to postmodern architectural discourse. These spaces are characterized by blurred boundaries and functional hybridity, with three primary typologies: introverted, extroverted, and independent. Their key functions include transitional connectivity, spatial emphasis, interaction stimulation, and functional adaptability. Empirical findings reveal distinct activity patterns among Hainan University students, highlighting a particular shortage of spaces for small-group interactions. Case studies of ambiguous spaces in libraries, teaching buildings, and concert halls demonstrate how vertical spatial sequencing, boundary softening, and functional blending effectively address tropical climatic conditions (high temperatures, strong solar radiation) while accommodating diverse social needs.
