A mechanomyography (MMG) signal input device, a human-machine operating system and an identification method thereof are provided. The system includes a mechanomyography (MMG) signal input device, a signal processing unit, a motion database and a calculating unit. The MMG signal input device is mounted on a measuring portion of a testing body, wherein the measuring portion has a plurality of muscle groups. The signal processing unit is used for receiving the MMG signals of the muscle groups, and performing integration and pre-processing on the MMG signals to obtain a processed signal. The motion database is used for storing a motion mode. The calculating unit is used for performing signal intensity computation, data segmentation, feature vector calculation, and testing body's motion recognition, and outputting a corresponding control signal according to the result of recognition.
