1. A gesture recognition apparatus for recognizing a gesture made by a person, comprising:

  • an ultrasound transmitter configured to send ultrasound signals;

    a ultrasound receiver configured to receive reflected ultrasound signals from an object;

    a dividing module configured to divide the reflected ultrasound signals into a plurality of frames according to a time interval;

    a computing module configured to obtain an eigenvalue of each frame;

    a classifying module configured to filter the eigenvalues to obtain gesture eigenvalues, and to obtain a matrix of probabilities of the gesture eigenvalues by using a sound recognition model;

    a gesture library comprising a plurality of reference matrixes of probabilities corresponding to a plurality of reference gestures; and

    a recognition module configured to search a reference matrix of probabilities from the gesture library for a match to the matrix of probabilities of the gesture eigenvalues; and

    recognize the gesture eigenvalues as a reference gesture corresponding to the reference matrix of probabilities if the reference matrix of probabilities is found.
