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 1, Anglais, - markerless%20tracking

[…] es necesario estimar la posición y orientación de la cámara con respecto al mundo real y viceversa. 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 1, Espagnol, - seguimiento%20de%20caracter%C3%ADsticas%20naturales

A sub-discipline of electronic countermeasures which covers a range of techniques used with aircraft, ships and missiles, in order to make them less visible (ideally invisible) to radar, infrared and other detection methods.  3, fiche 2, Anglais, - stealth%20technology

Record number: 2, Textual support number: 1 CONT

Stealth technology has as its fundamental principle the prevention of detection by the enemy, and applies not only to aircraft as is commonly assumed, but also increasingly to naval vessels and to armoured vehicles, although in the latter cases, it is nascent technology upon which comment must be reserved. Stealth technology, therefore, does not simply mean the evasion by aircraft of radar through the reduction of radar signature. It also encompasses the reduction of an aircraft's visibility in other spectra, most notably acoustic, visual, and infra-red. Consequently the popular term "stealth technology" would perhaps be better referred to as "low-observable technology. "  2, fiche 2, Anglais, - stealth%20technology

A supercell with "text-book" like features such as a well-defined hook echo on a radar scope and the precipitation core downwind of the wall cloud and rain free storm base.  2, fiche 3, Anglais, - classic%20supercell

Record number: 3, Textual support number: 1 CONT

Supercell [is] a thunderstorm with a persistent rotating updraft. Supercells are rare, but are responsible for a remarkably high percentage of severe weather events-especially tornadoes, extremely large hail and damaging straight-line winds. They frequently travel to the right of the main environmental winds(i. e., they are right movers). Radar characteristics often(but not always) include a hook or pendant, bounded weak echo region(BWER), V-notch, mesocyclone, and sometimes a TVS [Tornado Vortex Signature]. Visual characteristics often include a rain-free base(with or without a wall cloud), tail cloud, flanking line, overshooting top, and back-sheared anvil, all of which normally are observed in or near the right rear or southwest part of the storm. Storms exhibiting these characteristics often are called classic supercells; however HP(High Precipitation) storms and LP(Low Precipitation) storms also are supercell varieties.  3, fiche 3, Anglais, - classic%20supercell

The severe version of a worst-last storm is also a supercell type, and is either called a "classic supercell" (the standard supercell type) or an "LP (low-precipitation) supercell" - a dry-weather, high wind shear version. ... The classic supercell has a larger, darker appearance and accounts for most of the major tornado events everywhere.  4, fiche 3, Anglais, - classic%20supercell

Les orages de queue qui sont violents sont aussi de type supercellulaire; on les appelle des orages supercellulaires classiques ou à faibles précipitations (caractérisés par la présence d'air sec et d'un fort cisaillement du vent). [...] Les orages supercellulaires classiques sont de plus grande étendue et plus sombres; ce sont eux qui produisent la plupart des tornades, quelle que soit la région.  1, fiche 3, Français, - orage%20supercellulaire%20classique
