Abstract: Various implementations disclosed herein include devices, systems, and methods that provide color visual markers that include colored markings that encode data, where the colors of the colored markings are determined by scanning (e.g., detecting the visual marker using a sensor of an electronic device) the visual marker itself. In some implementations, a visual marker is detected in an image of a physical environment. In some implementations, the visual marker is detected in the image by detecting a predefined shape of a first portion of the visual marker in the image. Then, a color-interpretation scheme is determined for interpreting colored markings of the visual marker that encode data by identifying a set of colors at a corresponding set of predetermined locations on the visual marker. Then, the data of the visual marker is decoded using the colored markings and the set of colors of the color-interpretation scheme.

Abstract: A method includes determining a device location of an electronic device, and obtaining a content item to be output for display by the electronic device based on the device location, wherein the content item comprises coarse content location information and fine content location information. The method also includes determining an anchor in a physical environment based on the content item, determining a content position and a content orientation for the content item relative to the anchor based on the fine content location information, and displaying a representation of the content item using the electronic device using the content position and the content orientation.

Abstract: Various implementations disclosed herein include devices, systems, and methods that determine the relative positioning (e.g., offset) between a mobile electronic device and a visual marker. In some implementations, the determined relative positioning and a known position of the visual marker are used to determine a position (e.g., geo coordinates) of the mobile electronic device that is more accurate than existing techniques. In some implementations, the determined relative positioning is used with a position of the mobile electronic device to crowd source the stored position of the visual marker. In some implementations, the determined relative positioning and a position of the visual marker are used to determine a position of an object detected in an image by the mobile electronic device. In some implementations at an electronic device having a processor, locally-determined locations of a visual marker are received from mobile electronic devices that scan a visual marker.
