Room-scale virtual reality(VR), in which a user or "guest" can physically move within and interact with a virtual environment, is a very powerful and valuable addition to storytelling technology. Because room-scale VR allows a guest to walk around a physical play area, where the physical motions of the guest within the play area are reflected in the virtual environment, room-scale VR can provide a more compelling VR experience that is less dependent on being able to render high-quality visual and audio content. In particular, with a greater level of interaction available to a guest in room-scale VR, minor deficiencies in the presentation of video or audio content are less likely to detract from the immersive aspects of the room-scale VR experience, wherein a guest perceives that he or she is actually physically present in the virtual environment.  1, fiche 1, Anglais, - room%2Dscale%20virtual%20reality

With the advent of better graphic displays and faster computers, virtual reality and augmented reality have become an area of intense research with the expectation that substantial benefits can be derived from the ability to simulate or augment reality with computer-generated visual graphics. One such system is known as cave automatic virtual environment(CAVE) in which a large theater is situated within a larger room where the walls of the room or "cave" are made of rear projection screens and the floor is a down projection screen. A user of the virtual environment wears special glasses to see 3-D [tridimensional] graphics on the walls and floor of the cave.  1, fiche 2, Anglais, - cave%20automatic%20virtual%20environment

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, fiche 3, Anglais, - markerless%20tracking

La combinación de posición y orientación es llamada "pose" y en este caso se utilizaron dos técnicas de seguimiento o "tracking": seguimiento de marcadores cuadrados (marker-based tracking) y seguimiento de características naturales (markerless).  1, fiche 3, Espagnol, - seguimiento%20de%20caracter%C3%ADsticas%20naturales
