Abstract: A head-mounted device is provided that includes displays configured to display an image and to simultaneously display a magnifying window that presents a magnified portion of the image. The magnifying window lies in a magnification plane that is fixed relative to a user's head. One or more processors in the head-mounted device can be used to perform a first ray cast operation to identify an input point where a detected user input intersects the magnifying window, to obtain a remapped point from the input point, to compute a directional vector based on the remapped point and a reference point associated with the user's head, to obtain a shifted point by shifting the remapped point from the magnification plane to another plane parallel to the magnification plane, and to perform a second ray cast operation using the shifted point and the directional vector.

Abstract: Implementations of the subject technology provide virtual anchoring for extended reality (XR) display devices. A device may generate an XR environment that includes computer-generated (CG) content for display relative to various physical objects in a physical environment. In order to position the CG content, an XR application may request a physical anchor object to which the CG content can be anchored. In circumstances in which the physical anchor object is not available in the physical environment, a virtual anchor and/or a virtual anchor object corresponding to the physical anchor object can be provided to which the CG content can be anchored.
