Proceedings of the International Conference on New Interfaces for Musical Expression

This paper describes a study of membrane potentiometers and long force sensing resistors as tools to enable greater interaction between performers and audiences. This is accomplished through the building of a new interface called the Helio. In preparation for the Helio’s construction, a variety of brands of membrane potentiometers and long force sensing resistors were analyzed for their suitability for use in a performance interface. Analog and digital circuit design considerations are discussed. We discuss in detail the design process and performance scenarios explored with the Helio.
