On the analysis of saturated pressure to detect fatigue
This addresses fatigue detection for handwriting analysis, but it is incremental as it applies existing saturation analysis to new fatigue conditions.
The paper tackled the problem of detecting fatigue by analyzing pressure signal saturation during handwriting tasks, finding a significant rise in saturated samples after strenuous exercise without wrist rest.
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.
