A first extended reality (XR) device and a second XR device are colocated in an environment. The first XR device captures sensory data of a wearer of the second XR device. The sensory data is used to determine a time offset between a first clock of the first XR device and a second clock of the second XR device. The first clock and the second clock are synchronized based on the time offset and a shared coordinate system is established. The shared coordinate system enables alignment of virtual content that is simultaneously presented by the first XR device and the second XR device based on the synchronization of the first clock and the second clock.

Time synchronization for shared extended reality experiences

A method for aligning coordinate systems from separate handheld devices is described. In one aspect, the method includes accessing first pose data of a first handheld device, receiving second pose data of a second handheld device, detecting, from the first handheld device, hand-tracking data of a second user holding the second handheld device, and aligning a first coordinate system of the first handheld device with a second coordinate system of the second handheld device based on the first pose data, the second pose data, and the hand-tracking data of the second user holding the second handheld device.
