Abstract

This paper studies the dependence betweengeometry and kinematics in handwriting generationMovements. Based on a handwriting generationmodel developed earlier, movements parameters areextracted directly from on-line recording of velocityprofiles. These parameters, which reflect dynamicprocess, are found to be highly related to thegeometry of handwriting movements.The overall approach is based upon thehypothesis that complex human movements can besegmented into, basic and simple units. In otherwords, due to the intrinsic properties of theneuromuscular system involved in a rapid writingtask, there is a class of simple movements, hereaftercalled strokes. More complex movements are thusgenerated by the addition of the various strokesbelonging to such a class.
