Augmented man presents a vision of a new media technology, blending real and virtual world and has been developed in the context of an artistic exhibition. The visitor meets a virtual man, who seems to have emotions and who tries to get in contact by talking and asking questions. The application consists of augmented stereo videos, which are projected on a wall projection screen. The visitor sees himself like in a 3D mirror but with a new virtual person walking beside. The augmented man reacts topeople by approaching them or avoiding them.
This paper gives a complete overview of the exhibition and presents artistical concepts and the technical realization. After explanations about motivation and background ideas, the modelling and the behavior coding of the virtual man is described. Rendering aspects, like multi-texturing and 3D augmented videos are discussed in detail in the following sections. The determination of the positions of the visitors is achieved by processing images of a camera fixed at the room ceiling. Combined with the stereo front cameras, we finally show how occlusions between real persons and the virtual man can be handled. The system works in real-time on a single machine with three video input streams and two graphic outputs.
