Fig. 1From: Role of Muscle Synergies in Real-Time Classification of Upper Limb Motions using Extreme Learning MachinesTraining and Testing phase. a Represents the offline training phase, where the graphical user interface instructs the subject to perform specific movements for specific period of time. The EMG data is then used to build the decoding model which is specific for each subject. b The online testing phase, where EMG signals are decoded in real-time, and facilitates the movement of the virtual avatarBack to article page
