Much sensory-motor behavior develops through imitation, as during the learning of
handwriting by children. Such complex sequential acts are broken down into distinct motor …

This article focuses on dynamic signatures and their features. It provides a detailed and
critical review of dynamic feature variations and circumstantial parameters affecting dynamic …

Handwriting difficulties or dysgraphia have a profound impact on children's psychosocial
development, and yet, 10–30% of school-aged children are reported to experience …

We consider problems of motor redundancy associated with handwriting using the
framework of the uncontrolled manifold (UCM) hypothesis. Recent studies of finger …

Kinematic variability is caused, in part, by force fluctuations. It has been shown empirically
and numerically that the effects of force fluctuations on kinematics can be suppressed by …

Background Although various hand assist devices have been commercialized for people
with paralysis, they are somewhat limited in terms of tool fixation and device attachment …

Chau T, Ji J, Tam C, Schwellnus H. A novel instrument for quantifying grip activity during
handwriting. OBJECTIVE: To describe and exemplify a noninvasive instrumentation system …

Two views on the nature of motor programs are contrasted, one holding that motor programs
are discrete and integrated sets of movement goals, of which only the total size may be …

Normal subjects use an open‐loop motor control strategy in handwriting, but they are able to
switch to closed‐loop motor control when the demands on accuracy increase. These closed …

The aims of this study were to determine if computer‐measured dynamic features (duration,
size, velocity, jerk, and pen pressure) differ between genuine and simulated signatures …
