Accuracy of Musical Pitch Control Through Finger Pushing and Pulling

Abstract

An experiment with trained musicians was conducted to investigate how finger pushing and pulling gestures that control pitch bending of a synthesizer tone affect accuracy with respect to a given target pitch. Additionally, the effect of different interactive vibrotactile feedback was assessed. A self-developed haptic interface called TouchBox was used for this purpose. Finally, subjective evaluations were collected for perceived agency, confidence of correctness, and pleasantness of the experience.
