This property can be useful in implementing an sEMG decoder robust to the position changes of sensors (electrodes), since the electrodes attached at a position on human skin is not easy to be maintained for a long time. Experiments show that the sEMG decoder with the proposed method decodes human intentions from sEMG with a high accuracy and this performance is maintained even if the electrode position changes.
