AbstractWearable human-machine interfaces equipped with Inertial Measurement Units (IMUs) are widely used in healthcare, robotics, and interactive technology. However, extracting reliable signals remains challenging due to motion artifacts in real-world environments. This study presents a human-machine interface that withstands various motion artifacts through deep learning-enhanced wearable sensors. The system integrates a six-channel IMU, an electromyography … Read more
