MEASUREMENT OF HANDWRITING TREMOR FOR DIAGNOSTIC PURPOSES

Elzbieta Slubowska
Abstract:
Spectral analysis of the tremor signals got from the movement of the writing hand is presented in this paper. Analysis of stylus position and velocity is made upon data collected from the computer system for handwriting analyses, developed in Institute of Precision and Biomedical Engineering Warsaw University of Technology. Volunteers drew the circles on the digitiser surface using electronic pen similar to a normal ballpoint pen. Presented analyses were obtained from the group of 31 participants aged from 21 to 60 with different spectral analysis results of tremor measurements. Some of analyses were chosen to show differences between person without troubles in handwriting and that one whose handwriting is not easily readable because of some troubles with motorical skills or some diseases with pathological tremor, for example Parkinson's disease. As a results of my research I presented the method to classify the spectrum analyses for characteristic tremor group using numerical parameters.
