BioRhythm: A Biologically-inspired Audio Visual Installation

Work by: Ryan McGee, Yuan-Yi Fan and Rezi Ali

BioRhythm is an interactive bio-feedback installation con- trolled by the cardiovascular system. Data from a photo- plethysmograph (PPG) sensor controls sonification and vi- sualization parameters in real-time. Biological signals are obtained using the techniques of Resonance Theory in Hemo- dynamics and mapped to audiovisual cues via the Five Ele- ment Philosophy. The result is a new media interface utiliz- ing sound synthesis and spatialization with advanced graph- ics rendering. BioRhythm serves as an artistic exploration of the harmonic spectra of pulse waves.
