Abstract: Systems and methods are described for the coaching of users through successful calibration of a myoelectric prosthetic controller. The systems and methods are comprised of, and/or utilize, hardware and software components to input and analyze electromyography (EMG) based signals in association with movements, and to calibrate and output feedback about the signals. The hardware is further comprised of an apparatus for the detection of EMG signals, a prosthesis, an indicator, and a user interface. The software is further comprised of a user interface, a pattern recognition component, a calibration procedure, and a feedback mechanism. The systems and methods facilitate calibration of a myoelectric controller and provides the user with feedback about the calibration including information of the signal inputs and outputs, and messages about connected hardware and how to optimize signal data.
