Abstract: The invention provides a video conferencing system and a video conferencing method. The video conferencing system includes a sound sensor, an omnidirectional camera, and a processor. The sound sensor senses a first sound source and a second sound source, to provide a first positioning coordinate corresponding to the first sound source and a second positioning coordinate corresponding to the second sound source. The omnidirectional camera captures an omnidirectional conference image. The processor acquires a first facial image and a second facial image from the omnidirectional conference image according to the first positioning coordinate and the second positioning coordinate. The processor determines an image stitching order according to positions of the first facial image and the second facial image respectively in the omnidirectional conference image to generate a close-up conference image.

Abstract: Cellular devices and a pairing server implementing a Pairing method are described. The first cellular device includes a first subscriber identity module (SIM) card, a controller and a transceiver. The first SIM card is configured to store a first international mobile subscriber identity (IMSI). The controller is configured to receive a pairing command. The transceiver is configured to transmit the first IMSI without a Mobile Subscriber Integrated Services Digital Network-Number (MSISDN) in response to the pairing command.

Abstract: A method for configuring a remote device in a mobile device is provided. The method includes the steps of providing a dialogical user interface, obtaining a first position of the remote device, displaying a question message including information of the first position via the dialogical user interface, receiving an answer message corresponding to the question message via the dialogical user interface, and determining whether to set the first position as a safe zone for the remote device in response to whether the answer message is a confirmation message or a rejection message, wherein when the answer message is the conformation message, setting the first position as the safe zone of the remote device and displaying the setting result via the dialogical user interface.
