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.

Abstract: A method for browsing photo files in an embedded electronic device includes the following steps. A user interface window is displayed on a display. The user interface window includes a navigator bar and a content display area for showing photos, and at least one control button is loaded on the navigator bar for executing control functions to the photos. The electronic device detects if an external storage device is connected to the electronic device. A new resource button linking to the external storage device is created on the navigator bar when the external storage device is connected. Thumbnail image of each photo file from the external storage device is displayed on the content display area.

Abstract: A file sharing system includes a web server, a first electronic device, and a second electronic device. The web server includes an authorizing module and a server storage module. The server storage module is capable of storing files uploaded from a first electronic device. The authorizing module is capable of recording an authorizing setting from the first electronic device to authorize a second electronic device to access the files in the server storage module.
