Fig. 1From: Reducing the number of EMG electrodes during online hand gesture classification with changing wrist positionsExperimental setup. a Placement of the high-density electrode grids on the forearm of a participant. One electrode grid was placed on the ventral side of the distal forearm (grid 1) and three grids were positioned around the proximal forearm (grids 2 to 4). A red rectangle indicates the row of channels selected for uniform placement. b Lateral view of a participant with the arm in resting position (top) and with the elbow flexed at 90° (bottom) during the experimental sessionBack to article page
