| [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. | |
