Sensory Drawing Data reflects on a collaborative research project between Esther Rolinson and Sean Clark. It focuses on the use of computational processes to identify underlying structures and behaviours in Esther Rolinson’s drawings. The purpose of this is to define a movement language that can be used to control lights in Rolinson’s installation artworks. In this stage the work has a direct relationship to a series of public art works that Rolinson is currently developing in her role as Lead Artist for the building of a new surgical building for Musgrove Park Hospital, Taunton. It informs Rolinson and Clark’s shared curiosity about the structures embedded in human actions and sensations. It explores connections between handmade/human and digital processes of construction.
