This paper describes the video and audio tools that have been implemented in a real-type system to immerse a user into a virtual scene. The video tools include motion detection, skin detection by thresholding, shadow detection and extraction, and finally the user’s head and hands detection. Once this is done, the user (who is surrounded by a matrix of loudspeakers) is able to move a sound source in the horizontal plane around him. Moreover, the sound is auralized by convolution with (directional) room impulse responses, which have been pre-computed by a ray tracing method. The different sound contributions are distributed to the individual loudspeakers by applying the VBAP technique. [less ▲]

Numerous studies are currently focusing on the modelling of humans and their behavior in 3D environments. The CINEMA project has similar goals but differentiates itself by aiming at enhanced interactions, the creation of mixed reality, and the creation of interactive and reactive acoustical environments. Part of the project consists in gesture recognition of a user, who is given the real-time control of auralization and audio spatialization processes. [less ▲]

Pour l'acquisition vidéo grand public, la norme USB 1.1 est devenu le choix le plus courant en matière de standard d'interconnexion. Pour des applications à plus haut débit, les utilisateurs préfèrent recourir à des cartes d'acquisition vidéo dédiées ou à des normes d'interfaçage génériques, permettant des transferts à débit plus élevé. Cet article explique comment se servir de la norme IEEE 1394, aussi appelée FireWire ou i.Link, pour l'acquisition de séquences vidéo. [less ▲]
