(T)racing Eyes and Hearts is a research project where we are working towards creating an installation to explore the physiology of empathy. Our physiology responds to our environment in ways beyond our immediate awareness. The visualizations produced here present the heart rate, respiratory changes, and sweat response primarily using non-intrusive sensors. By tracking and visualizing data, we investigate and reflect upon the physiology of emotions experienced in response to human stories. This project was funded by GVU Small Research Grants.
