The breathing column is a scale model of a hypothetical architectural installation. Aiming to evoke an emotional and interactive relationship between people and the built environment, the column uses camera-based motion tracking to respond to the motions of people in a space. When someone moves around the column at a certain distance away, the outer shell of the column twists gently to trace the person's motion. When a person approaches the column closely, it begins to expand in a breathing motion, bending gently and emitting light from an array of lighting on the innermost layer.
