On the analysis of saturated pressure to detect fatigue

TL;DR

This study investigates how pressure signal saturation during handwriting tasks can serve as an indicator of fatigue, showing increased saturation after strenuous exercise, especially without wrist rest periods.

Contribution

It introduces an analysis of pressure saturation as a novel marker for fatigue detection in handwriting tasks under different physical exertion levels.

Findings

Saturation proportion increases after strenuous exercise

Significant differences in saturation between baseline and fatigue conditions

Wrist rest influences saturation levels during tasks

Abstract

This paper examines the saturation of pressure signals during various handwriting tasks, including drawings, cursive text, capital words text, and signature, under different levels of fatigue. Experimental results demonstrate a significant rise in the proportion of saturated samples following strenuous exercise in tasks performed without resting wrist. The analysis of saturation highlights significant differences when comparing the results to the baseline situation and strenuous fatigue.
