Extended Data Fig. 4: Handwriting signal analysis for in-air handwriting tasks.
From: Neural network-assisted personalized handwriting analysis for Parkinson’s disease diagnostics
a, Representative current signals from a recruited participant using the diagnostic pen to draw continuous wavy lines (Task 1) for three cycles in the air. b, Representative current signals from a recruited participant using the diagnostic pen to draw spirals (Task 2) for three cycles in the air. c, Representative current signals from a recruited participant using the diagnostic pen to write letters (Task 3) for three cycles in the air.
