Evaluating an Inertial Measurement Unit Based System for After-Reach Speed Measurement in Power Press Applications

Conference paper
Part of the Advances in Intelligent Systems and Computing book series (AISC, volume 795)


The objective of this study was to measure the hand speed of eighteen (18) subjects making after-reach movements from an upper palm button (UB) and lower palm button (LB) on a simulated press. Each after-reach movement was measured with a Vicon optical motion capture system and an Xsens IMU based system. A Bland-Altman analysis of the speed measured by the two technologies demonstrated a general agreement (average bias 0.19 m/s) between the measurements and a potential for using IMUs for hand-speed measures in the future. However, the computation intensity required to manipulate the Xsens data is likely too complex and time consuming for practitioners who are busy with plant activities. A simple IMU system, designed specifically for hand speed capture, could be a viable option for measuring after-reach speed in the future.
