Corpus of 3D natural movements and sign language primitives of movement
Résumé
This paper describes the development of a corpus or database of hand-arm pointing gestures, considered as a basic element for gestural communication. The structure of the corpus is defined for natural pointing movements carried out in different directions, heights and amplitudes. It is then extended to movement primitives habitually used in sign language communication. The corpus is based on movements recorded using an optoelectronic recording system that allows the 3D description of movement trajectories in space. The main technical characteristics of the capture and pretreatment system are presented, and perspectives are highlighted for recognition and generation purposes.
