Tracking location and resolving drift in augmented reality head mounted displays with downward projection

Abstract:

Embodiments provide for tracking location and resolving drift in Augmented Reality (AR) devices. The AR devices includes computing devices having screens on a first face and cameras on a second, opposite face to project an image onto optical arrangements for viewing by wearers of the AR devices. The AR devices map locations for real objects in the environment to a virtual environment; anchor virtual objects at anchor locations within the virtual environment; capture station keeping images of the environment from a first Field of View via the camera; determine a second, different Field of View in the environment for the wearer of the AR device based on the relative locations of real objects present in the station keeping images; and output images depicting the virtual objects at positions on the screen to depict the virtual objects in the physical environment at the anchor locations.
