Accuracy of Musical Pitch Control Through Finger Pushing and Pulling

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.
