Abstract

Provided are a method for time synchronization between a head-mounted device and a peripheral device. The method includes: obtaining sample data of an inertial measurement unit of the peripheral device, and determining a first timestamp representing a time at which the sample data is sampled; transmitting an interrupt request and the sample data to the head-mounted device, and determining a second timestamp representing a time at which the interrupt request is transmitted; determining a third timestamp representing a time at which the interrupt request is received by the head-mounted device; and determining a time difference based on the third timestamp and the second timestamp, and performing time compensation for the first timestamp based on the time difference to enable the peripheral device and the head-mounted device to complete the time synchronization with a unified time standard.
