The architecture of human motion information acquisition system based on surface EMG

The architecture of human motion information acquisition system based on surface electromyography (EMG) was described. Motion information is one of the most important techniques in the intelligent assistant production design, and it is a basis for the assistant system to supply appropriate and necessary actions. Thinking of the characteristics of daily tasks, this system adopted surface EMG as signal source. Then, the motion recognition method based on multi-class support vector machine and the muscle force (joint torque) calculation algorithm based on muscle physiological model and geometric model are proposed. The experiments results proved the effectiveness of this system.
