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

Description

This paper presents a new technique for interface-driven diffusion performance.Details outlining the development of a new tabletop surface-based performanceinterface, named tactile.space, are discussed. User interface and amplitudepanning 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 hopedthat the techniques described in this paper afford performers and composers anenhanced level of creative expression in the diffusion performance practice.This paper introduces and evaluates tactile.space, a multi-touch performanceinterface for diffusion built on the BrickTable. It describes how tactile.spaceimplements Vector Base Amplitude Panning to achieve real- time sourcepositioning. The final section of this paper presents the findings of a userstudy that was conducted by those who performed with the interface, evaluatingthe interface as a performance tool with a focus on the increased creativeexpression the interface affords, and directly comparing it to the traditionaldiffusion user interface.
