MULTI-TOUCH INTERFACES FOR PHANTOM SOURCE POSITIONING IN LIVE SOUND DIFFUSION

Bridget Johnson, and Ajay Kapur

Proceedings of the International Conference on New Interfaces for Musical Expression

Abstract:

This paper presents a new technique for interface-driven diffusion performance. Details outlining the development of a new tabletop surface-based performance interface, named tactile.space, are discussed. User interface and amplitude panning processes employed in the creation of tactile.space are focused upon,and are followed by a user study-based evaluation of the interface. It is hoped that the techniques described in this paper afford performers and composers an enhanced level of creative expression in the diffusion performance practice. This paper introduces and evaluates tactile.space, a multi-touch performance interface for diffusion built on the BrickTable. It describes how tactile.space implements Vector Base Amplitude Panning to achieve real-time source positioning. The final section of this paper presents the findings of a userstudy that was conducted by those who performed with the interface, evaluating the interface as a performance tool with a focus on the increased creative expression the interface affords, and directly comparing it to the traditional diffusion user interface.
