Abstract
An artificial reality system includes a head-mounted display (HMD) configured to output artificial reality content, wherein the HMD includes a first wireless transceiver to communicate with one or more devices of the artificial reality system; a peripheral device of the one or more devices of the artificial reality system configured to capture media samples for the HMD to output the artificial reality content, wherein the peripheral device includes a second wireless transceiver to communicate with the HMD; a clock manager of the HMD configured to compute a first delta between a timestamp of the HMD and a timestamp of the first wireless transceiver; and a clock manager of the peripheral device configured to compute a second delta between a timestamp of the peripheral device and a timestamp of the second wireless transceiver, wherein the first delta and the second delta are used to adjust a clock of the peripheral device.
