"From Driving to Expressive Music Performance: Ensuring Tempo Smoothness"
by Jie Liu (jieliu@usc.edu), Elaine Chew (echew@usc.edu) and Alexandre Francois (afrancoi@usc.edu)

ABSTRACT: 
This paper focuses on the mapping strategies in the interface
design for the Expression Synthesis Project (ESP). The goal of
ESP is to use the metaphor of driving to allow non-experts to
interactively create expressive renderings of music pieces. In
ESP, the road represents the music, with bends and straight
segments representing places where one might slow down and
speed up respectively. The user controls the tempo (rate of beats)
and dynamics (amplitude) by the way s/he drives through the
road. Our design objective in the ESP environment is to define
mapping strategies that guarantee tempo smoothness, a hallmark
of expert and practiced performances, under all driving
conditions. Because the road has non-zero width, several
strategies exist for mapping the cars that ensure tempo
smoothness, and provide mathematical and empirical proofs for
the success of these strategies.
