Implementations generate previews of the shared XR environment, such as a local preview and a remote preview.
Many users access artificial reality (XR) experiences through their mobile phones. However, it is difficult to translate XR experiences to a two-dimensional (2D) screen in a way that feels intuitive and natural. Thus, the technology can map an interaction plane in a three-dimensional (3D) scene to the 2D screen with as many affordances as possible, even if the plane is not parallel to the mobile phone. The plane can be a fixed surface or a dynamically changeable surface through which the user sends inputs through the 2D screen. The mapping of the plane to the 2D screen can control interaction with a virtual object on the interaction plane in the XR environment, enabling parity between the same experience on XR and non-XR interfaces.
