System for detecting intention of movements by a subject comprises sensors and a computing device. The sensors are configured to be engaged to the subject. The sensors measure electromyogram signals from the subject. The computing device receives the electromyogram signals from the sensors. Features are extracted using electromyogram signals from one or more of the sensors. One or more of the extracted features are compared with their respective threshold corresponding to a first movement among the movements. Intention of making the first movement is registered, prior to the onset of the first movement, based on the comparison.
