The Emotional Language of Space: A Study of Multisensory Design and User Perception in Interior Spaces examines how interiors speak to us emotionally through our senses. The study looks at visual cues such as color, light, and form; tactile qualities like materials and textures; olfactory signals through scent; and auditory experiences shaped by soundscapes. Together, these elements were explored to see how they influence emotions across different age groups and cultural contexts. A qualitative-first survey was conducted with 64 participants, using scenario-based prompts that asked them to imagine and describe how they would feel in spaces with specific sensory conditions--for example, natural sunlight, warm lighting, soft music, pleasant fragrances, or textured surfaces. Responses were examined using descriptive statistics and thematic interpretation to identify common emotional patterns. The findings highlight light as the strongest mood-setter: natural sunlight was almost universally associated with freshness and positivity, while warm light conveyed comfort and coziness. Sound shapes feelings of comfort, with noise increasing stress and soft music encouraging relaxation. Scent emerged as a subtle but powerful mood shaper, especially when matched to the function of a space. Textures also mattered, though reactions varied-- smooth surfaces were often seen as calming, while rough textures were described as either natural and grounding or uncomfortable. Most importantly, spaces where light, sound, and scent worked in harmony created the most positive emotional responses, whereas mismatched combinations caused unease. Age-related differences were also noted, with younger participants favoring brighter light and energy, and older participants showing more comfort with softer lighting and calming scents. The study concludes that interiors are not just visual environments but multisensory experiences. By weaving together light, sound, scent, and texture, designers can move beyond aesthetics to create spaces that feel emotionally supportive, engaging, and inclusive of different generational perspectives.
