The notion of contextualization has been introduced in an existing motion capture system driven by the segmented silhouettes of a person filmed from several points of view. The principle is to create a dependence of each module of the process (in this case, the different modules are the motion capture itself, the adaptive background modeling and the silhouette segmentation) from the results of the preceding ones. Thus, the influence of these elements, one with the other, guides locally the different computations. So, this optimization increases the reliability of the whole process while decreasing significantly its processing time. Yet it is obvious that this concept can be applied to several aspects of a motion capture system. As a matter of fact, it is possible to contextualize the captured motion, by modeling the context in which it takes place, allowing to make strong assumptions about the following sequence of movements executed by the filmed person. Thus, by recognizing the current and the next gestures of a captured person, the system can adapt its reactions and evolve with the constantly changing comprehension of the context by the player.
