Digito: A fine-grain gesturally controlled virtual musical instrument

Abstract

This paper presents Digito, a gesturally controlled virtual musical instrument. Digito is controlled through a number of intricate hand gestures, providing both discrete and continuous control of Digito’s sound engine; with the finegrain hand gestures captured by a 3D depth sensor and recognized using computer vision and machine learning algorithms. We describe the design and initial iterative development of Digito, the hand and finger tracking algorithms and gesture recognition algorithms that drive the system, and report the insights gained during the initial development cycles and user testing of this gesturally controlled virtual musical instrument.
