US Patent 12008151 Tracking and drift correction

Some implementations provide improved user interfaces for interacting with a virtual environment. The virtual environment is presented by a display of a first device having an image sensor. The first device uses the image sensor to determine a relative position and orientation of a second device based on a marker displayed on a display of the second device. The first device uses the determined relative position of the second device to display a representation of the second device including virtual content in place of the marker.
