Abstract: An electronic device includes a camera and two microphones. The space in front of the camera is divided into a plurality of imaginary cubic areas. Each imaginary cubic area is associated with a delay parameter. The camera locates a face of a user and determines an imaginary cubic area in which the face is located from the plurality of imaginary cubic areas. A wave beam pointing to the imaginary cubic area is calculated according to the delay parameter associated with the imaginary cubic area. The two microphone record voices within a range of the wave beam. A voice recording method is also provided.

Abstract: A method of sharing data in a computer-implemented system is provided. The system includes at least a publisher device and a viewer device. The system establishes a data communication connection between the publisher device and the viewer device via a Wi-Fi direct (WFD) network. The publisher device sends a desktop sharing request to the viewer device and receiving a character string from the viewer device. When the character string matches the security code, the publisher device transmits a shared desktop of the publisher device to the viewer device using the data communication connection.

Abstract: A method of sharing data in a computer-implemented system is provided. The system includes at least a publisher device and a viewer device. The system establishes a data communication connection between the publisher device and the viewer device via a Wi-Fi direct (WFD) network. The publisher device sends a desktop sharing request to the viewer device and receiving a first character string from the viewer device. The publisher device receives a second character string input by a user. When the first character string matches the second character string, the publisher device transmits a shared desktop of the publisher device to the viewer device using the data communication connection.
