The vBow: Development of a Virtual Violin Bow Haptic Human-Computer Interface
نویسنده
چکیده
This paper describes the development of a virtual violin bow haptic human-computer interface, which senses bow position with encoders, to drive bowed-string physical model synthesis, while engaging servomotors, to simulate the haptic feedback of a violin bow on a string. Construction of the hardware and programming of the software are discussed, as well as the motivation for building the instrument, and its planned uses.

متن کاملThe Vbow: Two Versions of a Virtual Violin Bow Controller
The vBow is a haptic musical controller human-computer interface, which simulates the forcefeedback of a bow on a violin string, while driving a bowed-string physical model. It is both a musical instrument for expressing the musical gestures of a performer, and a tool for testing friction and vibration models, and the responsiveness of physical model sound synthesis.
متن کاملThe vBow: A Four Degrees of Freedom Haptic Musical Controller Human-Computer Interface
This latest version of the vBow adds three degrees of freedom to the previous design, allowing for rotational motion across, vertical motion above, and longitudinal motion along the virtual strings, in addition to the original lateral motion of the bow stroke. Like the previous design, this version of the vBow uses servomotors with encoders and cable systems, to sense bow position and provide h...
متن کاملThe vBow: A Haptic Musical Controller Human-Computer Interface
The vBow senses the violinist's bow stroke through the encoder of a servo driven by a cable, which is wrapped around a capstan attached to the shaft of the motor, and secured to either end of the virtual bow. The servo engages the bow, simulating friction and vibration of the string on the bow, according to the velocity of the performer's stroke. The result is a musical controller capable of si...
متن کاملThe Bowed Tube: a Virtual Violin
This paper presents a virtual violin for real-time performances consisting of two modules: a violin spectral model and a control interface. The interface is composed by a sensing bow and a tube with drawn strings in substitution of a real violin. The spectral model is driven by the bowing controls captured with the control interface and it is able to predict spectral envelopes of the sound corr...
