Interval Player: Designing a virtual musical instrument using in-air gestures
Wallace S. Lages, Mahdi Nabiyouni, Javier Tibau, Doug A. Bowman · 2015
We present a novel virtual musical instrument interface based on in-air 3D gestures called the Interval Player. Instead of specifying absolute notes, the user specifies the melodic interval between the most recent note and the next one. The non-dominant hand is used to specify chords for harmony. We discuss the principles and rationale used in the design.
