Expressive Spaces are highly complex spaces made of several dozens of dimensions. Their are obtained statistically using automatic video sequences analysis. An Expressive Space can be created on demand in order to modelize the expressivity of somebody, and besides being applied on a virtual character in order to perform a real time control. Because such a space is very complex, a system using a sphere shaped interface  and enabling a simplified navigation has been developped. The expressions are, then, expressed more simply as a point in the sphere. It thus becomes very simple to "navigate" from an expression to another in a realistic manner.
