Figure 6From: Electromyogram synergy control of a dexterous artificial hand to unscrew and screw objectsThreshold mapping method: pseudocode logic. Pseudocode implementation of the Threshold input mapping method. E T is initialized to zero. If the magnitude of the EMG input |E| (1) is above a threshold γ, the input E T is incremented or decremented depending upon the relative contraction levels. If E E  > E F , E T is incremented to rotate the object clockwise, if E F  > E E , E T is decremented to rotate the object counterclockwise.Back to article page
