For a Reactive Virtual Trainer(RVT), subtle timing and lifelikeness
of motion is of primary importance. To allow for reactivity, movement
adaptation, like a change of tempo, is necessary. In this paper we
investigate the relation between movement tempo, its synchronization to
verbal counting, time distribution, amplitude, and left-right symmetry of
a clapping movement. We analyze motion capture data of two subjects
performing a clapping exercise, both freely and timed by a metronome.
Our findings are compared to results from existing gesture research
and existing biomechanical models. We found that, for our subjects, verbal
counting adheres to the phonological synchrony rule. A linear relationship
between the movement path length and the tempo was found.
The symmetry between the left and the right hand can be described by
the biomechanical model of two coupled oscillators.
