Abstract
The disclosure provides a gesture recognition apparatus and method. The gesture recognition apparatus includes an ultrasound transmitter, an ultrasound receiver, a dividing module, a computing module, a gesture library, and a recognition module. The dividing module is configured to divide reflected ultrasound signals into a plurality of frames according to time intervals. The computing module is configured to obtain an eigenvalue of each frame. The classifying module is configured to filter the eigenvalues to obtain gesture eigenvalues, and to obtain a matrix of probabilities of the gesture eigenvalues. The recognition module is configured to search reference matrices of probabilities from the gesture library for matching with the matrix of probabilities, and to recognize the gesture eigenvalues as a reference gesture corresponding to the reference matrix of probabilities if the reference matrix of probabilities is found.
