Abstract
Systems and methods for a more usable Augmented Reality (AR) display of navigation indications is described. A live camera image of a scene may be captured from a device. Navigation instructions may be generated from a navigation system and a navigation indication may be generated for display. A computer vision-based positioning algorithm may be performed on the camera image to determine the relative position between the viewpoint of the device and one or more landmarks in the live camera image. The location or shape of the visual display of the navigation indication may be determined based on the computer vision-based positioning algorithm.
