Designing a Digital Musical Instrument
1. Decide upon the gestures which will control it
2. Define the gesture capture strategies which work best
3. Define the accompanying synthesis algorithms / music software
4. Map the sensor outputs to the music control
5. Decide on the feedback modalities available,
apart from the sound itself (visual, tactile, kinaesthetic, etc.)
New Digital Musical Instruments: Control and Interaction Beyond the Keyboard
Miranda & Wanderley

Mapping – an overview
“A more holistic performance exploration of the parameter space”
Radical User Interfaces for Real-Time Musical Control
Hunt
“An efficiency-focused approach to interaction may no longer
suffice: it needs to be complemented by knowledge on the
aesthetic aspects of the user experience”
Easy doesn’t do it: skill and expression in tangible aesthetics
Djajadiningrat, Matthews & Stienstra

Mapping in product design
“…in a manner spatially analogous to the
layout of the devices they control”
The Design of Future Things

Mapping in product design
The Design of Future Things
Norman
1. Provide rich, complex, and natural signals
2. Be predictable
3. Provide a good conceptual model
4. Make the output understandable
5. Provide continual awareness, without annoyance
6. Exploit natural mappings to make interaction understandable

Begins with…
A careful look at the resources available…

Some thoughts…
• The potential for a musical performance system to engage,
challenge and stimulate the user depends upon how their
actions are interpreted by the system.
• Every performance action sends information into the system.
• It is critical that we grasp all possible ways to interpret this
data.
