Abstract: Embodiments of this application disclose a synchronization method and a device. A device marks, based on a preset period, a periodic code block in a data bitstream to be sent from a MAC layer to a PHY layer. The device sends the data bitstream to a peer device through the PHY layer, records a sending time of each periodic code block as a first timestamp during sending, and returns the first timestamp to the MAC layer. By marking a timestamp for the periodic code block received from the MAC layer, the device sets a PHY-layer-based time reference scale (namely, the first timestamp) at the PHY layer.

Abstract: A terminal with a line-of-sight tracking function is disclosed. The terminal with a line-of-sight tracking function includes a body, a camera, and at least two light emitting diodes. The camera and the at least two light emitting diodes are mounted on the body, so that the terminal can emit a ray by using the at least two light emitting diodes, to ensure that the emitted ray can be shined on an eye of the user when the user is at different angles. After the ray is reflected by the eye of the user, the terminal can collect the reflected ray by using the camera, obtain an eye image of the user, and track a line of sight of the user based on the eye image, thereby increasing a success rate of line-of-sight tracking.
