Research on Multi-Sensory Experience Design of Interior Space from the Perspective of Spatial Perception: A Case Study of Suzhou Coffee Roasting Factory

With the globalization and transformation of social and cultural structures, spatial demands are increasingly shifting from a focus on mere functionality to an emphasis on sensory experiences and the cultivation of atmosphere. This study explores spatial perception theory, integrating it with the principles of perceptual phenomenology, to examine the factors influencing spatial perception from two key dimensions: sensory experience and the physical characteristics of space. For instance, visual elements such as lighting, color, and spatial form influence the emotional tone of a space by shaping mood and setting expectations. Auditory design, including soundscapes and sound timing, plays a critical role in fostering comfort and immersion. Building upon these insights, the study proposes an interior design strategy centered on multi-sensory engagement: (1) Visual Perception: Modifying color and lighting to establish emotional ambiance and enhance spatial depth; (2) Auditory Perception: Crafting soundscapes that deepen immersion; (3) Tactile Perception: Designing both direct and indirect tactile experiences; (4) Olfactory and Gustatory Perception: Incorporating scent design to evoke memory and forge emotional connections. To validate these strategies, we analyze the design of lighting, color, materials, and scent in a coffee roasting factory in Suzhou, where a balanced space was created that not only meets functional requirements but also elevates sensory stimulation and the immersive experience for customers. This study bridges the gap between multi-sensory design and spatial ambiance, offering a systematic framework and advocating for the transition from functional design to one that prioritizes multi-sensory engagement.
