Abstract: An adaptive rearview mirror adjustment method includes obtaining a spatial position of a human eye of a driver of a current vehicle and a spatial position of a target rearview mirror, obtaining a horizontal field of view of the driver in the target rearview mirror based on the spatial position of the human eye of the driver and a spatial position of a target rearview mirror, obtaining a next-vehicle image, obtaining a first auxiliary angle of a target next vehicle based on the next-vehicle image, calculating a second auxiliary angle based on the horizontal field of view, the spatial position of the human eye, and the position of the target rearview mirror, obtaining a horizontal adjustment angle of the target rearview mirror based on the first auxiliary angle and the second auxiliary angle, and adjusting a horizontal angle of the target rearview mirror based on the horizontal adjustment angle.

Abstract: A device searching method includes a first device that obtains a relative location between a second device and the first device is based on location information of the first device and the location information of the second device; if it is determined, based on the relative location, that the second device is not within a shooting range of the first device, the first device indicates to move the first device toward the second device until the second device is within the shooting range of the first device; and the first device highlights the area in which the second device is located in the shooting range of the first device.

Abstract: A data stream transmission method includes: sending a first target signal; obtaining a first moment, where the first moment is obtained based on a time point at which a first receiving device on a second device receives the first target signal; obtaining a second moment, where the second moment is obtained based on a time point at which a second receiving device on the second device receives the first target signal, where the first receiving device and the second receiving device are located at different positions of the second device, and the second device is a head-mounted device; and when determining, based on the first moment and the second moment, that a data transmission condition is met, transmitting a target data stream to the second device.

Abstract: A method and an apparatus for detecting a relative location between devices is disclosed. The detection method includes: obtaining a first target audio signal obtained by a first microphone of a device B; determining a first audio segment and a second audio segment based on a first target moment and the first target audio signal, where the first target moment is a moment determined in the first target audio signal based on a target amplitude; separately searching for the first audio segment and the second audio segment to obtain a first arrival moment and a second arrival moment; and determining a relative location between a device A and the device B based on the first arrival moment and the second arrival moment.
