Detrended fluctuation analysis of repetitive handwriting

Although there is a tendency that the opportunity to write by hand is decreasing, handwriting is still one of the everyday activities of our lives. In this study, the experimental system that limits the writing speed of a subject was set up. The aim was to measure the fluctuation time series of a time element obtained from the measurement performed using detrended fluctuation analysis. The result confirmed the local self-similarity and that it covers multiple timescales.
