Absolute differences of SAL results for referential motion capture system (Optotrak) based hand velocity and various IMU based approaches. First box presents results for hand velocity determination as integral of IMU dynamic acceleration vector (S A L A c c), while second and third box present angular velocity based hand velocity calculation for 1 IMU per forearm (S A L G y r o 1) and 2 IMUs per arm (S A L G y r o 2) sensor placement.
