Trazo sonoro y sistemas neurogestuales algorítmicos: Dibujo, EEG y OSC como ecología transdisciplinar de pensamiento

Abstract

This article examines the expansion of drawing as a transdisciplinary system of thought through the integration of sensory and neurophysiological data. Based on a practice‑based research‑creation methodology focused on the sonification of the drawing gesture using contact microphones, it analyzes how acoustic feedback reshapes the perception of movement and reconfigures the act of drawing as a multisensory and somatic process. The research is further developed through the prototyping of Neuro_Sonic::Draw_Synthesis, an experimental system that integrates the recording of brain activity via EEG (OpenBCI) and its synchronization with microacoustic movement signals. This phase, currently in a beta stage, focuses on the technical validation of OSC data flow between OpenBCI and visual programming environments such as TouchDesigner, exploring the feasibility of real‑time communication between biosensors, visual processing, and sound synthesis. The convergence of gesture, sonification, neural signals, and algorithmic data translation allows for the proposal of an expanded ecology of drawing as an interface between art, science, and technology. From this perspective, drawing is framed as a device for perceptual and cognitive translation, opening new pathways for understanding visual thinking, embodied cognition, and contemporary forms of creativity mediated by human–machine systems.
