Abstract
A method and system of visually communicating navigation instructions can use translational and rotational arrow cues (TRAC) defined in an object-centric frame while displaying a single principal view that approximates the human's egocentric view of the actual object. A visual guidance system and method can be used to pose a physical object within three-dimensional (3D) space. Received pose data (402) indicates a current position and orientation of a physical object within 3D space, such that the pose data can provide a view of the physical object used to generate a virtual view of the physical object in 3D space. At least two of six degrees of freedom (6DoF) error can be calculated (404) based on a difference between the current position of the physical object and a target pose of the physical object. The 6DoF error can include a three degrees of freedom (3DoF) position error and a 3DoF orientation error which can be used to determine a translation direction and a rotation direction to move the physical object to align a pose of the physical object with the target pose of the physical object within a tolerance. One of both of a translation cue and a rotation cue can be output (408…
