Ergonomics of Touch-screen Interfaces
Abstract
The design of digital musical instruments , freed from the physical constraints of acoustics, is essentially driven by issues in ergonomics and representation related to the musical context. Moreover, the programmability of virtual instruments allows dynamic reconfigurations of mapping relationships between gestural interfaces and synthesis. In this respect, graphical interfaces stand on the edge between representation and control. Recently enhanced by the advent of multitouch, they allow all kind of tangible interactions. Their customization (behaviour, shape, colour, etc.) plays a crucial role, whether for the virtuosity of professional musicians, for the accessibility of people with disabilities or for particular contexts such as collective interaction on the same touch-screen. I will first raise a few aspects of visual ergonom-ics that inspired this research then present recent developments of dynamic, polyphonic and customizable touch-screen interfaces, based on the concept of "dynamic intermediate model" and an ad-hoc protocol for expressive control.
