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.
