The appraisal of the velocity-curvature relation in children' hand movements: a research note.
A coupling between hand speed and the shape of the hand path appears to be present early in human development. This note addresses the issue of how such a feature may be appraised within digitally recorded trajectories and, in particular, highlights some problems with previously used techniques that may lead to misinterpretation of data. A new approach to such analyses is proposed.
