sEMG for gesture recognition

They are a combination of 8 finger gestures and 3 wrist gestures. The 8 finger motions include fist, extension of all fingers, extension of thumb finger, extension of index finger, extension of thumb and index finger, extension of little finger, 3-fingers pinch, and 5-fingers pinch . And the 3 wrist motions are wrist extension, wrist flexion and wrist relaxation. 8-channel sEMG and 1-inertial measurement unit (IMU) were recorded by a self-developed device. The sampling frequency of sEMG and inertial signal was 1000Hz. Twenty right-handed healthy subjects (ten males and ten females) between 18 and 30 years of age from Xi’an Jiao-tong University with no neuromuscular disorders, upper limb motor dysfunction and no strenuous exercise within 24 hours participated in the experiment.
