Abstract: A communication apparatus, a synchronization method, and a system are provided. The communication apparatus includes a wireless communication unit, a clock circuit, and a control module. When an electronic device in which the communication apparatus is located is a primary device, the wireless communication unit is configured to send a signal used for synchronization of a communication clock signal. When an electronic device in which the communication apparatus is located is a secondary device, the wireless communication unit is configured to receive the signal that is used for synchronization of a communication clock signal and that is sent by the primary device. The clock circuit may generate a data processing clock signal based on the communication clock signal. The control module may perform data processing and/or control a data output based on the data processing clock signal.

Abstract: The present disclosure relates to virtual reality interaction methods, devices, and systems. In one example method, a head-mounted display device displays a virtual keyboard. In response to an input trigger operation of a user, a hand-mounted device sends hand detection data to the head-mounted display device based on a detected target sensor signal. After determining, based on the hand detection data, that an input trigger event occurs, the head-mounted display device determines an initial tap position of a target finger relative to the virtual keyboard based on a hand image captured by a camera. The hand-mounted device sends hand motion tracking data collected by a motion sensor to the head-mounted display device. In response to an input completion operation of the user, the head-mounted display device determines and displays an input result based on the initial tap position and the hand motion tracking data.
