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, videos and web sites are displayed on a second computer. Navigating through the data is done with a 3D sensor with six degrees of freedom that simulates a virtual camera. Interactive request can be formulated by the expert with a data glove that recognizes the gestures. We show how this tool has been applied to a real world application in the context of human skin analysis. MOTS-CLÉS : fouille visuelle de données, visualisation de données, interaction utilisateur.
