Many Digital Music Instruments (DMI) are composed of an input controller connected to a general-purpose computer. But as computers evolve we witness a proliferation of new form/factors, bringing us closer to the possibility of embedding computing in everyday tangible objects. This fact may have a considerable impact on future DMI design, through the convergence between gestural interface and processing unit, materialized into Self-contained DMIs.
By bypassing general-purpose computers and their imposed interaction modalities, these instruments could be designed to better promote embodied knowledge through enactive interfaces, while still maintaining many of the capabilities of computer-based systems. This context suggests the research of novel interaction models and design frameworks.
“The Mitt” is a Self-contained Digital Music Instrument which explores the capture of high-resolution finger gestures through its tangible interface. It is a first implementation using an ARM embedded system, customized for sensor data acquisition and sound synthesis, and capable of dynamic re-configuration.
