Schneider, Andréia Rodrigues de Assunção. "Animação de humanos virtuais aplicada para língua brasileira de sinais." reponame:Biblioteca Digital de Teses e Dissertações da UFRGS, 2008. http://hdl.handle.net/10183/15313.
Full textDeaf people have a limited capacity of using oral language to communicate. Because of this, they use gestural languages as their native language. This makes it especially difficult for them to make use of basic services in a satisfactory way and to properly integrate the hearing world, to which the majority of the population belongs. Due to the fact that this language is only gestural, it is possible to say that the signs it comprises of can be simulated with the animation of virtual humans without losing the correct perception of their inherent meanings (what words they represent). This work describes a technique of animation for LIBRAS. The main idea is to take the movement of a sign from a description of its animation and execute it in a more or less wide manner in order to better use the available space for gesticulation without losing the meaning. The computer animation of a sign must be as close to the real gesture as possible. Its meaning must be easily understood and its execution must be natural (smooth and continuous). For that, the signs must be defined in accordance with the movement limitations imposed by the human joints, and the field of view of the receiver. Besides that, some relevant parameters must be analyzed and defined: speed of the movement, time and amplitude of the signs. Another important aspect to be addressed is the space that is available for the execution of the sign: depending on the area, the sign must be animated in a manner that makes it properly fit in it. The implementation of the technique resulted in a animation system for LIBRAS, that consists of three modules: • a virtual human modeler, so that the joints and DOFs are anatomically consistent with reality; • a gesture generator, which is responsible for the processing of parameters such as speed, time of execution of the gesture, joint configuration, in a file that describes the animation of the pose. It is worth emphasizing that the words in LIBRAS are known as signs. Already a sign is composed of one or more gestures and they are composed of poses; • an animator, which is responsible for generating the animation of a previously created sign, fitting (if necessary) the sign amplitude to the space available for its animation. The generated system has been submitted for tests in order to validate the technique. The goal of the tests was to check whether the generated signs were understandable - if the generated animation represented a certain word. All aspects above are presented and analyzed in detail.

Full textNowadays, Sign Language (SL) is still little described, particularly for what concerns the movement of articulators. Research on SL has focused on understanding and modeling linguistic properties. Few investigations have been carried out to understand the kinematics and dynamics of the movement itself and what it brings to understand the LS SL generated by models. This thesis deals with the analysis of movement in the French Sign Language LSF with a main focus on its production as well as its understanding by deaf people.Better understanding the movement in SL requires the creation of new resources for the scientific community studying SL. In this framework, we have created and annotated a corpus of 3D motion data from the upper body and face, using a motion capture system. The processing of this corpus made it possible to specify the kinematics of the movement in SL during the signs and the transitions.The first contribution of this thesis was to quantify to what extent certain classical laws, known in motor control, remained valid during the movements of SL, in order to know if the knowledge acquired in motor control could be exploited in SL.Finding relevant information of the movement that is crucial for understanding SL represented the second part of this thesis. We were basically interested to know which aspects of the movement of SL production models should be replicated as a priority. In this approach, we have examined to what extent deaf individuals, whether signers or not, were able to understand SL according to the amount of information available to them

Full textThe studies and the software presented in this work are addressed to a relevant minority of our society, namely deaf people. Many studies demonstrate that, for several reasons, deaf people experience significant difficulties in exploiting a Vocal Language (VL English, Chinese, etc.). In fact, many of them prefer to communicate using Sign Language (SL). As computer scientists, we observed that SLs are currently a set of underrepresented linguistic minorities in the digital world. As a matter of fact, deaf people are among those individuals which are mostly affected by the digital divide. This work is our contribution towards leveling the digital divide affecting deaf people. In particular, we focused on the computer handling of SignWriting, which is one of the most promising systems devised to write SLs

Full textThe fundamental question this thesis sets out to explore is the following: does the lexicon of contemporary English exhibit traces of a notional invariance possiby dating back to a very early stage of the language? The answer is provided through the study of three initial consonant segments: bl-, kn-, and sk-. With this aim in view, three heuristic classes are set up, namely ‘bl- words', ‘kn- words', and ‘SK- words', the latter including lexemes beginning in sc-, sch-, sh-, sk-, and sq-. These three initial consonant segments have been chosen because they are representative of the three main types of English phonesthemes (CR-, ØR-, and SC-). The overall objective is to show that the semiological invariance of each of these classes corresponds to a notional invariance: I claim that these submorphemic segments are the surface marks of an invariance whose source may be traced back to a very ancient process of conceptualization and nomination of the human body. My study involves four dimensions: a lexicological analysis leading on to semantic and etymological analyses. Finally, drawing on various approaches of ‘cognitive' linguistics, I suggest a description of the way the brain conceptualizes the referents of the lexemes belonging to the three classes examined, based on the works of Lakoff & Johnson, Fauconnier & Turner, Langacker, and Talmy
Mercier, Hugo. "Modélisation et suivi des déformations faciales : applications à la description des expressions du visage dans le contexte de la langue des signes." Phd thesis, Université Paul Sabatier - Toulouse III, 2007. http://tel.archives-ouvertes.fr/tel-00185084.
Full textLe formalisme des modèles à apparence active (Active Appearance Models - AAM) est utilisé ici pour modéliser le visage en termes de déplacements d'un certain nombre de points d'intérêt et en termes de variations de texture. Quand il est associé à une méthode d'optimisation, ce formalisme permet de trouver les coordonnées des points d'intérêt sur un visage. Nous utilisons ici une méthode d'optimisation dite "à composition inverse", qui permet une implémentation efficace et l'obtention de résultats précis.
Dans le contexte de la langue des signes, les rotations hors-plan et les occultations manuelles sont fréquentes. Il est donc nécessaire de développer des méthodes robustes à ces conditions. Il existe pour cela une variante robuste des méthodes d'optimisation d'AAM qui permet de considérer une image d'entrée éventuellement bruitée.
Nous avons étendu cette variante de façon à ce que la détection des occultations puisse se faire de manière automatique, en supposant connu le comportement de l'algorithme dans le cas non-occulté.
Le résultat de l'algorithme est alors constitué des coordonnées 2D de chacun des points d'intérêt du modèle en chaque image d'une séquence vidéo, associées éventuellement à un score de confiance. Ces données brutes peuvent ensuite être exploitées dans plusieurs applications.
Nous proposons ainsi comme première application de décrire une séquence vidéo expressive en chaque instant par une combinaison de déformations unitaires activées à des intensités différentes. Une autre application originale consiste à traiter une vidéo de manière à empêcher l'identification d'un visage sans perturber la reconnaissance de ses expressions.

Full textBy being subjected to a combination of vulnerabilities, deaf persons in jail are calling for a review of their situation. To what extent does their legal status take this into consideration? How can public law effectively accommodate them through its regulatory role? While deaf persons in jail may be insensitive to the noises which characterize the prison environment, they are nevertheless sensitive to the silence which surrounds them. Locked into the medical vision of disability, French law is unable to listen to nor meet their needs. Deaf to their requests and to those international obligations to which it has committed itself, France keeps these people in inhuman and degrading conditions of detention. The social isolation which derives from this reflects a society inaccessible to deafness and an absence of effective legal recognition
