Abstract
A new steering interface was designed to develop an innovative steering system for our assisted human powered vehicle. In order to evaluate the steering maneuverability of the innovative steering system, we had conducted ergonomics study by Electromyography (EMG). The EMG signals of the human driver's shoulder and upper limb muscles were acquired via experiments to investigate the physiological behaviors of the steering maneuvers. From the analysis, we had identified the main muscles and characteristics involve in the steering maneuver of this innovative steering system.
