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)
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)
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)
Interactive editing of utterances in French sign language dedicated to signing avatars Signing avatars dedicated to French Sign Language (LSF) are more and more used as a communication interface for the deaf community. One of the acceptation criteria of these avatars is the natural and realistic aspect of the constructed gestures. Consequently, gestures(More)
This paper describes the human-scale virtual reality (VR) platform with force feedback developed at the LISA laboratory in Angers (France) in collaboration with Professor Makoto SATO. A human-scale SPIDAR system provides force feedback to user’s hands using 8 motors placed on the corners of a cubic frame (2m x 2.5m) surrounding the user. Stereoscopic images(More)
