Methods and systems are disclosed for creating a shared augmented reality (AR) session. The methods and systems perform operations comprising: receiving, by a second device, a request to join an AR session initialized by a first device; in response to receiving the request, detecting a body corresponding to a user of the first device in one or more images captured by a camera of the second device; identifying a body part of the detected body corresponding to the user of the first device; determining, by the second device, a transformation in the AR session between the first device and the second device using the identified body part; and causing the AR session to be displayed by the second device based on the determined transformation.
