… ARToolkit library is used for marker-based tracking in real scenes … Large markers are used for large virtual objects, such as furniture … Using large markers makes the recognition and registration easier and more reliable. With large markers, online consumers can bring virtual furniture or other large virtual products into their homes, and view it in a farther distance. Otherwise it will bring more instability since marker tracking is based on computer vision technology.  3, record 1, English, - marker%2Dbased%20tracking

Le suivi par marqueur a été grandement popularisé par l'outil ARToolkit […] Un marqueur […] est une image avec de fortes contraintes […] Elle possède les caractéristiques suivantes : l'image est carrée, sa dimension est connue dans la scène réelle, elle est en noir et blanc, elle est entourée d'une épaisse bande noire, et elle possède un identifiant unique au centre du carré.  1, record 1, French, - suivi%20par%20marqueur

[…] 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, record 1, Spanish, - seguimiento%20de%20marcadores%20cuadrados

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 2, English, - markerless%20tracking
