Signing avatars are increasingly used as an interface for communication to the deaf community. In recent years, an emerging approach uses captured data to edit and generate sign language (SL) gestures. Thanks to motion editing operations (e.g., concatenation, mixing), this method offers the possibility to compose new utterances, thus facilitating the(More)
The L-system is a rewriting process based on formal grammar and is used to generate 3D, dynamic structures such as virtual plants and fractal graphics. In previous works, we highlighted that existing L-system software applications and programs are limited, either in terms of human interaction or in terms of modelling. In particular, few of them allow the(More)
RÉSUMÉ Les avatars signeurs en Langue des Signes Française (LSF) sont de plus en plus utilisés en tant qu'interface de communication à destination de la communauté sourde. L'un des critères d'acceptation de ces avatars est l'aspect naturel et réaliste des gestes produits. Par conséquent, des méthodes de synthèse de gestes ont été élaborées à l'aide de(More)
Humans possess the ability to perform complex manipulations without the need to consciously perceive detailed motion plans. When a large number of trials and tests are required for techniques such as learning by imitation and programming by demonstration, the virtual reality approach provides an effective method. Indeed, virtual environments can be built(More)
