A Wireless Glove to Perform Music in Real Time

In this paper, we present a “wireless glove” that we propose as a new musical instrument; it is able to control a real time granular sound synthesis process. The glove was adopted to detect intrinsic and extrinsic hand movements, thanks to sensors on back-hands, palm and fingers. Sensors realized with piezoresistive materials change their electrical resistivity when deformed. The piezoresistive coefficient is defined by the ratio of the change of the relative resistivity caused by the change of the relative length of resistor. In addiction to the piezoresistive sensors we also use a kinematic transducer that measure hand motion acceleration, it is composed by three mono-axial accelerometers. Finally, the musical synthesis process was realized by means of a sound synthesizer based on granular additive synthesis algorithm.
