Abstract
This project explores the use of wearable wireless sensors for the generation and
manipulation of music from dance performances. The design of a prototype wireless
sensor that includes dual-axis accelerometers and three single-axis gyroscopes is
discussed. The input of sensor data to a Pd (Pure Data) patch is explored and possible
mapping strategies for a system of sensors is discussed.
1. Introduction
This project investigates the use of a new wireless sensor system for
interactive dance performances. Such a system would allow the dancer to control the
generation or manipulation of their own musical paniment and could be useful
in a variety of ways including the choreography stage as well as the performance
itself. The implementation consists of two ponents: a series of wireless body
sensors worn by the dancer and a Pd object for the real-time manipulation of the data
received from these sensors. The development process consisted of four main steps:
• a study of the properties of the device used
• the creation of an interface between the device and a puter
• the creation of a new object to input the data into Pd
• the tracking and manipulation of the sensor data
The chosen sensor is an array of accelerometers and gyroscopes which are used to
track the dancer’s movements.
Sensors
Sensors are ponents whose purpose is to transform different
types of physical energy into data. It mon to distinguish between wearable and
non-wearable sensor types depending on whether or not they are worn by a performer.
