Abstract : A system for measuring the displacement, velocity, and acceleration of hand-writing movements has been developed. Samples of handwriting processed by this system indicate that the acceleration waveforms of uninterrupted handwriting approximate multilevel trapezoidal time functions. Electronic simulation of the measured displacement, velocity, and acceleration waveforms of handwriting has been accomplished. The 'handwriting' produced by the electronic simulator can duplicate uninterrupted handwriting with a high degree of accuracy. The simulator represents a point mass driven by a trapezoidal 'force' function. Preliminary results have been obtained which are directed toward the establishment of relations between the model and the biological system responsible for handwriting. Possible applications of the techniques and apparatus developed in this report to problems of handwriting recognition and neurological studies are discussed. (Author)
