[en] 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.
