Abstract
Motivation of the studies of human handwriting process is derived chiefly from the realization that the studies of handwriting process have the potential to increase our knowledge of the function and organization of a biological system through the study of a common but sophisticated function of that system.
This report is divided into four parts. In the first part, studies are initiated by designing and constructing a handwriting analyzer by which measurements are made of vertical and horizontal projections of displacement of a pencil-point and writing pressure as well as EMG records of muscle activities in the forearm during handwriting or related movements. In the second part, the equivalent dynamic model of handwriting process is proposed by generalizing the model first presented by D. Van der Gon. In the next, experiments concerning the guiding of human handwriting movements are carried out, in which the equivalent muscular force model is given. In the last, the equivalent dynamic model of handwriting process proposed here is proved to be successful through the synthetic studies of handwriting.
