A tactile bio-signal installation where touching living plants triggers cascading audiovisual responses — Arduino-driven sensors translate botanical electrical impulses into real-time light, sound, and projected visuals through TouchDesigner, transforming the space between human skin and leaf into an audiovisual journey at fingertip.




Concept & Bio-Signal
Plants are not silent — they conduct electricity, respond to touch, and communicate through bioelectric signals invisible to the human eye. Floriograph intercepts these micro-voltage fluctuations using capacitive and galvanic skin response sensors wired through Arduino, translating the plant's electrical language into data streams that drive real-time audiovisual output. The result is a living interface: touch a leaf, and the room responds.
Technical Pipeline
An Arduino Mega reads analog signals from bio-sensors attached to plant stems and leaves — capturing voltage changes as small as millivolts when human skin makes contact. These readings stream via serial communication into TouchDesigner, where custom signal-processing networks map bio-data to visual parameters: particle density, LED color temperature, projection intensity, and spatial audio triggers. The entire pipeline runs at 60fps with sub-100ms latency from touch to response.
Light & Tactile Interaction
Addressable LED strips woven through the plant arrangement shift hue and brightness in direct response to touch intensity and duration — gentle contact produces cool teal washes, sustained pressure builds into warm amber pulses. Projected visuals on the surrounding walls amplify the signal into large-scale generative patterns, while the cinematic teal-and-orange color palette — captured in the documentation — emerged organically from the interplay between LED hardware and TouchDesigner's real-time compositing.
