MyKinSynthr is a technique we have developed to synthesize EMG signals over multiple EMG electrodes placed on a person”s forearm to develop a musculo-skeletal model of human body. The musculo-skeletal model represents rich sources of human movement temporal information, including time-varying data on torque, stiffness, joint angles, and postures. We use this model to estimate the person”s intended 3D motion and force.
