Virtual reality entertainment systems utilizing head mounted displays or other immersive devices or methods, whereby a participant views and interacts with a software-generated virtual reality environment have been used for training and entertainment purposes for many years. An immersive virtual reality environment as used and described herein refers to a computer generated graphical environment wherein a participant is "immersed" within the environment so as to provide to the user a sensation of being physically located within the graphical environment, although the participant is only electronically present with other objects within the environment. Therefore, an immersive virtual reality environment creates an illusion to the participant that he or she is in an artificially created environment through the use of three-dimensional (3D) graphics and computer software which imitates the relationship between the participant and the surrounding environment.  1, fiche 1, Anglais, - immersive%20virtual%20reality%20environment

There are various forms of immersive virtual environments. Some, such as rooms or cabins(CAVEs), that offer semi-immersive experiences in which users can see virtual worlds projected on physical displays. Others, such as head mounted displays(HMDs), have more compact setup and fuller immersion than CAVEs, and have gained recent popularity due to improvement in hardware and software... However, users’ immersive experiences depend on, not only rendering/display performance but also interaction and navigation capabilities.  2, fiche 1, Anglais, - immersive%20virtual%20reality%20environment

Une interaction homme-environnement virtuel immersif (IHEVI) est mise en œuvre dans un environnement virtuel immersif (EVI). Dans un EVI, les informations sensorielles du monde réel sont remplacées par des stimuli synthétiques (e.g., image stéréoscopique, son spatialisé, retour haptique, …) […] Ainsi, la finalité de ces environnements est de «permettre à une ou plusieurs personne(s) une activité sensori-motrice et cognitive dans un monde artificiel, créé numériquement, qui peut être imaginaire, symbolique ou une simulation de certains aspects du monde réel» [...]  2, fiche 1, Français, - environnement%20virtuel%20immersif

Dans le cadre de la réalité virtuelle, un environnement immersif est un environnement partiellement ou totalement artificiel, créé autour de l'utilisateur. Les environnements immersifs ont de nombreuses applications : simulateurs (de vol, de conduite...), prototypage, bureaux virtuels, environnements d'ambiance, jeux vidéo… Deux types de systèmes peuvent produire de tels environnements : les systèmes portables comme les casques de réalité virtuelle […]; les systèmes grand écran comme les CAVEs [Cave Automatic Virtual Environments].  4, fiche 1, Français, - environnement%20virtuel%20immersif

Técnicamente, un entorno inmersivo de realidad virtual es un sistema compuesto de hardware específico que consigue la estimulación de los sentidos, principalmente de la vista mediante la proyección de imágenes, para hacer que el usuario se sienta dentro de un modelo digital, junto a un software de simulación en tiempo real que genere las imágenes que el usuario verá.  1, fiche 1, Espagnol, - entorno%20inmersivo%20de%20realidad%20virtual

One interesting 3D [three-dimensional] movement to model in particular is viewpoint transformation(as in camera panning, zooming, and translation). This is critical for interactive graphics applications like virtual reality(VR) navigation, in which the camera perspective changes continuously under user control.  1, fiche 2, Anglais, - virtual%20reality%20navigation

The primary challenge in acoustic modeling is computation of reverberation paths from a sound’s source position to a listener’s receiving position. As sound may travel from source to receiver via a multitude of reflection, transmission, and diffraction paths, accurate simulation is extremely compute intensive.  2, fiche 3, Anglais, - acoustic%20modeling

Computer-aided acoustic modeling tools are important for design and simulation of three dimensional environments. For instance, an architect might use such a tool to evaluate the acoustic properties of a proposed auditorium design. Or, a factory designer might be able to predict the sound levels of any machine at any position on a factory floor. Acoustic modeling can also be used to provide sound cues to aid understanding, navigation, and communication in interactive rates. For example, the voices of users sharing a virtual environment may be spatialized according to each user's avatar location.  2, fiche 3, Anglais, - acoustic%20modeling

orb : the orb is a smaller sphere, about the size of a billiard ball, set in a base, like a joystick. It can be pushed, pulled, and rotated. In some ways, the orb is a better control device than the glove. The glove is indispensable in establishing your sense of presence and giving ou a literal handle for manipulating the virtual world, but the orb is far easier to use for navigation in cyberspace.  1, fiche 4, Anglais, - orb%20input
