Effect of speed on handwriting shape: a descriptive generalization.
In this report, we characterize the natural simplifying
transformations of a handwritten curve. We argue that the number and
type of singularities in a geometric curve determine the amount of
time required for the human handwriting system to produce that curve
to a given level of accuracy. Therefore, the behavior of the human
handwriting system under increasing time pressure may be characterized
by a set of stochastic transformations that replace costly curve
segments with less costly segments, or remove segments entirely.
