The Cardiomorphologies series explores the subjective spaces created through interaction with a simple geometric visualisation of realtime heart and breath rate data. The installation is comprised of one large floor-to-ceiling video projection, that is controlled by heart and breath signals from the participant who is seated a few meters way.
The core focus with this work was on translating heart and breath information using concentric circles – to create a kinaesthetically compelling but extremely simple visual design that could be experienced in varying states of attention (i.e. with soft gaze), inspired by mandala imagery and tunnel like visuals often described in connection to near-death experiences – vision at a threshold.
Between 2004 and 2006 several different versions where exhibited, beginning with a very stark, hard-edged visualisation designed with John Tonkin, and ending in the multi-layered and highly dynamic visualisations developed with Lizzie Muller and Greg Turner between 2005–2006.
Breath is measured using a stretch sensor worn around the participant’s chest (now using a hal effect sensor), and heart rate data is obtained via wireless sensors. All the data is analysed, and features extracted and mapped to sounds and visuals (circle diamter, colour etc.) using Max-MSP (programming by George Khut with Greg Turner).
