Sougwen Chung's Study series shares process artefacts from her collaborative research with the 4th generation of her Drawing Operations project – focused on biofeedback and digitized drawing memory. The work was created alongside the D.O.U.G._4 system, which Chung designed to better understand the possibilities of enacting robotic movement with my own biosignals. The system works through a camera attached to the end of the robotic arm, which relays the position of her own hand as data. As Chung make marks on canvas, D.O.U.G._4 responds to her based on real-time interpretations of her brainwaves, to which she then respond. This deceptively simple process creates a feedback loop of overlapping paint strokes, resulting in a visual outcome. It is a painting study and a research artefact, part of an ongoing speculation about alternative configurations of human and machine interaction as collaborative art.
