Force-Sensitive Resistors

Force-sensitive resistors are located on the inside of the index finger for actuation by the pad of the thumb, and on the anterior of thumb for actuation by the pad of the index finger, allowing continuous control of two parameters with only partial release of the bow grip.

Flex Sensors

Flex sensors are distributed on the index and fourth fingers, reflecting the horizontal pivoting of the bow in the hand as well as situations in which the bow is gripped (pizzicato) or the fourth finger lifted from the stick to achieve a “transparent sound” (Ivan Galamian). A bi-directional flex sensor on the wrist serves as a proxy for the lateral position of the bow on the strings.

Motion Sensing

A motion sensor is built into a circuit board resting proximal to the wrist, uniquely secured with an elastic band and bracket. Oriented this way, gyroscopic z-axis readings accurately represent bowing velocity, while x-axis movements represent string crossings.

Additional Features

Three contact switches are available, as well as vibro-tactile feedback. A “poetic” computation scheme is implemented in Max MSP utilizing continuous gesture tracking. Alto.glove is cost-effective and easy to build.
