A bioelectricity-based control method, device and controller, enhancing natural interactions between humans and machines. The method comprises: collecting a surface electromyography signal generated when a user performs a finger pressing operation (200); extracting a characteristic of the collected surface electromyography signal to obtain characteristic information (210); determining, according to a pre-established finger type identification template, a finger type used to perform the finger pressing operation and corresponding to the obtained characteristic information (220); and mapping the determined finger type used to perform the finger pressing operation to a corresponding first instruction, and controlling, according to the first instruction, controlled equipment (230). The invention can implement control over the controlled equipment by a more harmonious and natural communication method between humans and machines.
