The Evaluation of Classifier Performance during Fitting Wrist and Finger Movement Task Based on Forearm HD-sEMG

Figure 5

Using the number of fitting channels as 8, the curve was fitted when the hand was open and closed. (1) The red line in the figure represents the sequence of characteristic curves of wrist movements. (2) The green line represents the sequence of characteristic curves of finger movements (hand open or close). (3) The blue curve represents actual acquired data of finger-wrist coordination. (4) The black curve represents the composite action data after fitting. (a) Hand close and wrist. (b) Hand open and wrist.
