The inventors have recognized the benefits of providing an augmented reality system that may be capable of automatically identifying and tracking features within a three-dimensional environment for the purpose of projecting information into the three-dimensional environment to instruct an operator in a specific procedure. In one embodiment, a method for providing an augmented reality includes the steps of: identifying a feature within a three-dimensional environment; projecting first information into the three-dimensional environment; collecting an image of the three-dimensional environment and the projected information; determining at least one of distance and orientation of the feature from the projected first information in the collected image; identifying an object within the three-dimensional environment; and performing markerless tracking of the object. In another embodiment, a method for providing augmented reality includes the steps of: collecting visual information of an environment; identifying a plurality of features within the environment; comparing the plurality of features to a visual signature to identify a situation; performing markerless tracking of the plurality of features; and providing a visual prompt to a user regarding the identified situation. 1, record 1, English, - markerless%20tracking
