The virtual-real measurement of Chinese garden impression: A quantitative analysis of cognitive experience of Jiangnan gardens with virtual reality experiments

Traditional Jiangnan garden architecture in China offers distinct spatial impressions that hold significance in contemporary architectural expression. Yet, the understanding and analysis of these spaces have historically relied on subjective, sensory experiences, often lacking precise, quantitative research. Consequently, establishing clear logical connections between visual cognition and emotional perception within these spatial experiences has been a challenge. This study introduces virtual reality spatial simulation and quantification techniques, summarizing key Jiangnan garden spatial characteristics and prototypes. It includes a series of virtual reality experiments focusing on cognitive experiences within Jiangnan garden spaces. A comprehensive analysis of isovisit quantitative data, questionnaires, and behavioral information explores the logical relationships between emotional perceptions (calmness, surprise, interest, confusion) and visual cognition qualities (openness, complexity, theatricality) in garden space impressions. This research aims to reveal deeper connections between garden space qualities, visual cognition, and emotional experiences, offering valuable insights for the application of historical traditional spatial features in contemporary architecture. It bridges the gap between sensory experiences and rational analysis, enhancing our understanding of the intricate spatial narratives within Jiangnan gardens.
