Digital morphogenesis and bioAffective data: A computational framework for multisensory design

The integration of biometric data and sensory stimuli is reshaping architectural computing, expanding design possibilities beyond traditional visual and geometric parameters. Through ‘Hydnum’, named after a genus of fungi known for its distinctive geometric mycelial networks, we demonstrate the integration of real-time biodata with virtual and physical elements to create dynamic spatial experiences. Our computational framework synthesizes olfactory, auditory, and visual elements through a sophisticated scent delivery mechanism, bio-inspired geometric structures, and real-time audio synthesis, all modulated by users’ physiological responses mapped to Russell’s Circumplex Model of Affect. The system leverages biosignal processing and transformations to engage underutilized senses in architectural design, while the project’s modular scent system and cyber-physical artifacts create responsive environments. Through empirical testing and systematic integration of multiple sensory channels, this research advances biodigital architecture by providing a comprehensive framework for spaces that actively engage with users’ emotional and physiological states.
