Methods, devices, and systems for producing augmented reality

A system for augmented reality (AR), comprising

• one or more virtual markers stored in a virtual world that is modeled after a real world environment;
• at least one upstream AR engine configured to
• select one or more of the virtual markers from the virtual world based on a location associated with one or more real world objects depicted by real world content of an image or video;
• apply the one or more selected virtual markers to the image or video, wherein the one or more selected virtual markers are AR augmentations;
• wherein the one or more applied virtual markers are configured to trigger a downstream AR engine to augment the real world content of the image or video with one or more further augmentations, wherein the downstream AR engine has a preexisting association among the one or more further augmentations and the one or more applied virtual markers,
• wherein, from a perspective of the downstream AR engine, the one or more applied virtual markers are configured to be recognizable and differentiable from both the real world content and AR augmentations which are not virtual markers.

A method for augmented reality (AR), comprising

• based on a camera's location and pose, associating first virtual content with real world content captured by the camera, the first virtual content and real world content both being image or video content configured for concurrent display, wherein the first virtual content is one or more virtual markers which are AR augmentations;
• selecting second virtual content by processing an image or video frame containing both the first virtual content and the real world content, wherein selection of at least some of the second virtual content is triggered by the presence of the first virtual content, the second virtual content being usable for producing one or more further AR augmentations;
• and
• initiating a signal for controlling an augmented reality output by an output device, the output including the selected second virtual content and the real world content,
• wherein the steps of associating, selecting, and initiating are performed by one or more AR engines,
• wherein, from a perspective of an AR engine performing the selecting step, the one or more virtual markers are configured to be recognizable and differentiable from the real world content and AR augmentations which are not virtual markers.
