“…The collection process was simple and non-invasive, making it a popular research field in human-machine interaction technology. At present, a fair amount of representative research on motion intention recognition based on sEMG has been reported, which can be broadly divided into two categories: classification of the motion pattern [9,10,11,12,13,14] and estimation of the continuous motion of the joint [15,16,17,18,19]. Many classification methods applied continuous sEMG signals to estimate joint angles with predefined sets, such as support vector machine [9], artificial neural network [10], gaussian mixture model [11] and other classifiers [12,13,14].…”
