Référentiels Spatiaux des Tâches d'Interaction et Caractéristiques de l'Utilisateur influençant la Performance en Réalité Virtuelle

In virtual reality, to adapt interfaces to users, two dimensions must be studied: the task and the user. The first dimension deals with interaction tasks in virtual reality, more precisely manipulation and locomotion. The study and the comparison of spatial properties of virtual and real environments allow us to propose tasks hierarchical models which show problematical interaction situations f...

Exploration de données multimédia par réalité virtuelle

We present a new 3D interactive method for visualizing multimedia data (numeric, symbolic, sounds, images, videos, Web sites) with virtual reality. We use a 3D stereoscopic display in order to let the expert easily visualize and perceive the numerical attributes. We add to this display the appearing of contextual information such as texts, voice synthesis, sound, small images. Larger images, vi...
