Proceedings of the International Conference on New Interfaces for Musical Expression

This paper presents a framework that transforms fingerprint patterns intoaudio. We describe Digiti Sonus, an interactive installation performingfingerprint sonification and visualization, including novel techniques forrepresenting user-intended fingerprint expression as audio parameters. In orderto enable personalized sonification and broaden timbre of sound, theinstallation employs sound synthesis based on various visual feature analysissuch as minutiae extraction, area, angle, and push pressure of fingerprints.The sonification results are discussed and the diverse timbres of soundretrieved from different fingerprints are compared.
