Synergistic Myoelectrical Activities of Forearm Muscles Improving Robust Recognition of Multi-Fingered Gestures

Abstract: Currently, surface electromyography (sEMG) features of the forearm multi-tendon muscles are widely used in gesture recognition, however, there are few investigations on the inherent physiological mechanism of muscle synergies. We aimed to study whether the muscle synergies could be used for gesture recognition. Five healthy participants executed five gestures of daily life (pinch, fist, open hand, grip, and extension) and the sEMG activity was acquired from six forearm muscles. A non-negative matrix factorizat… Show more

“…The signal of sEMG is an electrical signal generated by the potentials generated through the contraction of many fiber bundles in the muscles, which are superimposed in time and space, such as in Figure 6. The signal has strong volatility and instability [17]. In Figure 7, we can see that the fluctuations of sEMG signals in different sign languages are different.…”

“…Recognizing multiple gestures is a challenge as the recognition accuracy decreases with the increase in the number of gestures. Table 1 summarizes examples of previous literature attempting to recognize several gestures [10,[14][15][16][17][18][19][20][21][22][23][24][25].…”

“…Wearable sensors include electromyography (EMG), touch sensors, strain gauges, flex sensors, inertial sensors, and ultrasonic sensors [8]. Among wearable sensors, wearable inertial sensors may be the most widely employed for human-motion recognition [9,10]. In general, inertial sensors refer to sensor systems consisting of accelerometers and gyroscopes, and magnetometers.…”
