|dc.description.abstract||This thesis investigates the use of multidimensional control of synthesis parameters
in electronic music, and the impact of controller mapping techniques on creativity.
The theoretical contribution of this work, the EARS model, provides a rigorous
application of creative cognition research to this topic. EARS provides a cognitive
model of creative interaction with technology, retrodicting numerous prior findings
in musical interaction research. The model proposes four interaction modes, and
characterises them in terms of parameter-space traversal mechanisms. Recommendations
for properties of controller-synthesiser mappings that support each of the
modes are given.
This thesis proposes a generalisation of Fitts' law that enables throughput-based
evaluation of multi-dimensional control devices.
Three experiments were run that studied musicians performing sound design tasks
with various interfaces. Mappings suited to three of the four EARS modes were
Experiment one investigated the notion of a `divergent interface'. A mapping geometry
that caters to early-stage exploratory creativity was developed, and evaluated
via a publicly available tablet application. Dimension reduction of a 10D synthesiser
parameter space to 2D surface was achieved using Hilbert space-filling curves. Interaction
data indicated that this divergent mapping was used for early-stage creativity,
and that the traditional sliders were used for late-stage one tuning.
Experiment two established a `minimal experimental paradigm' for sound design
interface evaluation. This experiment showed that multidimensional controllers were
faster than 1D sliders for locating a target sound in two and three timbre dimensions.
The final study tested a novel embodied interaction technique: ViBEAMP. This
system utilised a hand tracker and a 3D visualisation to train users to control 6
synthesis parameters simultaneously. Throughput was recorded as triple that of
six sliders, and working memory load was signiffcantly reduced. This experiment
revealed that musical, time-targeted interactions obey a different speed-accuracy
trade-of law from accuracy-targeted interactions.||en_US
