In this paper, we propose an EMG (electromyography) signal processing method for easy wearing EMG interfaces that can be attached or put on like clothes, supporters, etc. Although we can expect that such wearable EMG interfaces realize convenient multipoint EMG sensors, problems would arise in contacting electrodes, e.g., the positions and contacting conditions of the electrodes can easily change. To cope with this problem, we propose a method for choosing a few representative electrodes out of the may ones attached to a wearable interface. This selection makes recongnition more reliable and reduces the computation time in a training (parameter adjusting) phase. Our experimental result on fingers dorsiflexion motions shows that the proposed method works properly for a middle finger. The result also suggests that our method is applicable to the other fingers by using more electrodes.
