Diane Gromala’s responsive font types (2000-present).
“BioMorphic Typography is Gromala’s term for a family of fonts that respond, in real-time, to a user’s changing physical states, as measured by a biofeedback device. Rather than one typeface, it is a postmodern pastiche of many different fonts that are continually morphing. So, for example, the font “throbs” as the user’s/writer’s heart beats. In this way, users become aware of their autonomic states. This project is part of a larger initiative, Design for the Senses. The goal is to develop new approaches to experiential design that focus on the senses and the history of the body” (From the web site).
