Over the past decade, many fields of discovery have begun to use motion capture data, leading to an exponential growth in the size of motion databases. Querying, indexing and retrieving motion capture data has thus become a crucial problem for the accessibility and usability of such databases. Our aim is to make this approach feasible for virtual agents signing in French Sign Language, taking into account the semantic information implicitly contained in sign language data. We propose a new

This approach is used to effectively retrieve stored motions for the purposes of producing real-time sign language animations. The complete process and its in-use efficiency are described, from querying motion in the semantic database to computing transitory segments between signs, and producing animations of a realistic virtual character.
