Compréhension robuste de la parole spontanée dans le dialogue oral homme-machine : décodage conceptuel stochastique by Caroline Bousquet-Vernhettes( Book )

2 editions published in 2002 in French and held by 4 WorldCat member libraries worldwide

La problématique de la thèse concerne l'élaboration d'un modèle de compréhension littérale robuste de la parole spontanée dans un contexte d'application finalisée. Le mémoire expose d'abord la problématique de la compréhension robuste. Nous présentons ensuite notre modélisation fondée sur une approche stochastique et conceptuelle. Nous présentons les principes retenus pour l'élaboration de deux modèles de langage de granularité différente. Puis, nous proposons des extensions de notre modèle afin de faire face à la présence de mots mal reconnus et d'optimiser la compréhension en considérant le contexte du dialogue
Transmodalité et multimodalité écrit/oral : modélisation, traitement automatique et évaluation de stratégies de présentation des structures "visuo-architecturale" des textes by Fabrice Maurel( Book )

2 editions published in 2004 in French and held by 3 WorldCat member libraries worldwide

We are interested in the utility and, if the need arises, the usability of texts visual structure, within the framework of their oral transposition. We propose the synoptic of an oralisation system who leads to a text representation directly interpretable by Text-To-Speech systems. We partially realized the module specific to the oralisation strategies, in order to render some signifying parts of the text often “forgotten” by synthesis systems. The first results of this study led to specifications in the course of integration by an industrial partner. Predictive hypothesis, related to the impact on memorizing/understanding of two strategies coming from our Reformulation-based Oralisation Model for Texts Written to be Silently Read (MORTELS), have been formulated and tested. This work shows that cognitive functions was lost. Prototypes, exploiting the “Page Reflection” notion, have been conceived through interfaces in which multimodality is used to fill this gaps
Adaptation dynamique des stratégies de dialogue aux usagers : application aux personnes âgées by Régis Privat( Book )

2 editions published in 2004 in French and held by 3 WorldCat member libraries worldwide

This thesis deals with the adaptation of dialogue strategies in interactive voice systems and aims at taking into account age-related disabilities. Our work focuses on: The study of the utility / usability of oral input for the elderly; The assessment of a running dialogue performance; The definition of adapted dialogue strategies through the study of man-machine dialogue corpora. This work has led us to design experimental scenarios (subjects, supports, parameters), in order to build up objects of study (including the oral input and the dialogue strategies) and to assess their performances (utility, usability). In order to this, we have also developed components allowing us to test these dialogue strategies within a test platform

Modèles psychophysiques d'atteintes de cibles pour les personnes souffrant de troubles neuromusculaires by Frédéric Vella( Book )

2 editions published in 2008 in French and held by 2 WorldCat member libraries worldwide

The studies on able-bodies showed that the text input is faster with physical AZERTY keyboard (75 Words Per Minute) than with virtual AZERTY keyboard with pointing (25 Words Per Minute). This reduction of speed is also observed during text input activity by disabled people with the UKO ambiguous keyboard. On the contrary, other studies show the benefits of optimizing the layout of the keys for the text input, under conditions of mobility for the OPTI and Metropolis keyboard and in office situation for the GAG keyboard. Thus, to understand and describe the motor deficiencies, we need to study the motor activity by applying the psychomotor law. This study have a double issue (theoretical and technological interest): the understanding of the motor deficiencies and the design of systems (such as virtual keyboards) based on interaction techniques of pointing. The objective is to propose a modeling of motor performances (and eventually perceptual performances) of our study population to predict the time necessary to move and to research targets. To achieve this goal, we studied the reaching of targets with 1 dimension. These models are then applied to study the usability of a software keyboard
Etude phonétique de la dysarthrie parkinsonnienne : effet d'un traitement pharmacologique by Karine Rigaldie( Book )

2 editions published in 2006 in French and held by 2 WorldCat member libraries worldwide

This works aims to acquire a better knowledge of prosody disturbances in Parkinson disease via an acoustic analysis. The investigation of the patients' vocal productions by the way of acoustic analyses should indeed allows two things. Firstly, to identify phonetic and prosodic parameters that are specific of such a pathology. Secondly, to study the effect of a pharmacological treatment (based on dopamine) on these patients'speech production. In order to determine the effect of dopamine, oral productions of 14 parkinsonian patients of the akinetic type have benne collected, in the OFF and ON states, and have then been compared to those of control subjects. The specific aim of this study is (a) to examine the ability of patients to handle the variations in fundamental frequency of their voice as well as to master the rise in frequency required by the task (i.e. production of the musical scale and intonation patterns) and (b) to measure the palliative effects that can be induced, at least partly, in the management of frequency by a treatment based on L-Dopa. More precisely, we will endeavour to study the prosodic behavior (variation of the acoustic parameters of frequency, intensity and duration) of the parkinsonian subjects in the production of the musical range and two intonation patterns. Indeed, we hypothesize that musical scale production would be an indicator of the subjects' capacity to produce intonation schemas according to a given instruction. If that is correct subject evidencing difficulties in ascending the scale would similarly have problems in handling adequately intonation patterns in language production (e.g. assertions, questions, etc.)
Analyse, modélisation et détection automatique des disfluences dans le dialogue oral spontané contraint : le cas du contrôle aérien by Jean-Léon Mehdi Bouraoui( Book )

2 editions published in 2008 in French and held by 2 WorldCat member libraries worldwide

Les disfluences sont un phénomène apparaissant fréquemment dans toute production orale spontanée ; elles consistent en l'interruption du cours normal du discours. Elles ont donné lieu à de nombreuses études en Traitement Automatique du Langage Naturel. En effet, leur étude et leur identification précise sont primordiales, sur les plans théorique et applicatif. Cependant, la majorité des travaux de recherche sur le sujet portent sur des usages de langage quotidien : dialogues " à bâtons rompus ", demandes d'horaire, discours, etc. Mais qu'en est-il des productions orales spontanées produites dans un cadre contraint ? Aucune étude n'a à notre connaissance été menée dans ce contexte. Or, on sait que l'utilisation d'une " langue de spécialité " dans le cadre d'une tâche donnée entraîne des comportements spécifiques. Notre travail de thèse est consacré à l'étude linguistique et informatique des disfluences dans un tel cadre. Il s'agit de dialogues de contrôle de trafic aérien, aux contraintes pragmatiques et linguistiques. Nous effectuons une étude exhaustive des phénomènes de disfluences dans ce contexte. Dans un premier temps nous procédons à l'analyse fine de ces phénomènes. Ensuite, nous les modélisons à un niveau de représentation abstrait, ce qui nous permet d'obtenir les patrons correspondant aux différentes configurations observées. Enfin nous proposons une méthodologie de traitement automatique. Celle-ci consiste en plusieurs algorithmes pour identifier les différents phénomènes, même en l'absence de marqueurs explicites. Elle est intégrée dans un système de traitement automatique de la parole. Enfin, la méthodologie est validée sur un corpus de 400 énoncés
Influence des propriétés de surface sur les performances de localisation d'icônes et de mots sur un écran : quelles recommandations pour un public âgé ? by Caroline Moget( Book )

2 editions published in 2015 in French and held by 2 WorldCat member libraries worldwide

This thesis in ergonomics is part of an industrial design project of an innovative e-health system (HADAGIO), developed by the company SESIN and allowing home support frail elderly. Its goal was applied to produce ergonomic recommendations for improving the interfaces of the system proposed in the form of a web portal software to make them easier to use and thus promote the final acceptance HADAGIO the device.This work has focused on the task of locating information on a screen and, in particular, the role of perceptual features (color and detail) lexical icons and labels on achieving performance of this task by elders. This task is indeed particularly difficult for this people who get lower localization performances than young people (reaction times and a larger number of errors). The models proposed for the target location task assumes that the knowledge possessed by individuals on the appearance of the target to locate allow improved performance. Given that advancing age does not affect the process involving knowledge stored in memory (Top Down type) implemented in this task it was to determine what could be the color of the role and Details of the target level in the implementation of these processes at a location task information.Graphics recommendations for HADAGIO portal interface design have emerged from this work, and provide information to facilitate the localization task for the elderly
Systèmes de saisie de textes pour les personnes handicapées moteur : optimisation, interaction et mesure de l'utilisabilité by Mathieu Raynal( Book )

2 editions published in 2005 in French and held by 2 WorldCat member libraries worldwide

Cette thèse aborde des problèmes d'optimisation, de conception et d'utilisabilité de nouveaux systèmes d'aide à la communication pour personnes handicapées moteur des membres supérieurs. La problématique est de diminuer les distances à parcourir (avec le pointeur du dispositif de pointage) pour saisir du texte. Ces travaux s'articulent autour de 2 propositions d'optimisation : a) l'application des algorithmes génétiques pour optimiser la disposition des caractères sur le clavier logiciel ; b) le système KeyGlass qui propose au fur et à mesure de la saisie des caractères supplémentaires (grâce à des moteurs de prédiction de caractères) à proximité du dernier caractère saisi. Pour pouvoir mesurer l'apport des optimisations proposées et de leur utilisabilité, nous avons réalisé la plateforme d'évaluation E-Assiste qui a pour objectif de combler un manque de corpus de tests et d'environnements d'évaluation et permettre l'étude des usages de nos systèmes in situ
Study of the interaction of older adults with touchscreen by Lilian Genaro Motti Ader( Book )

2 editions published in 2016 in English and held by 2 WorldCat member libraries worldwide

Tablets and smartphones have become mainstream technologies. However, the aging effects on the motor skills implied on tactile interaction haven't been enough considered during the design and evaluation of tactile interactive systems, what prevent this group of older adult users to be digitally included successfully. This thesis aims to study the interaction of older adults with touchscreens in order to identify usability issues on different devices and input modalities (smartphone and tablet, finger and stylus). To this study, we designed an interactive system consisted of tactile puzzle games and using drag-and-drop interaction for positioning the puzzle pieces into their corresponding targets. In this framework, a special attention was given to the analysis of the movements of the user. The analysis of the postures of the users' wrists during interaction allowed to elucidate the relationship between the characteristics of the movements of older adults and their performances, particularly concerning the longer times needed for executing the gestures of interaction as well as the increased error rates of this group of users when compared to younger adults. Taking into account the variability of users' motor skills during the design and evaluation of interactive systems is necessary to better understand their difficulties as well as to improve the ergonomics and the usability levels of tactile interaction
Constitution d'un corpus de dialogue oral pour l'évaluation automatique de la compréhension hors et en contexte du dialogue by Journées d'études sur la parole( )

1 edition published in 2009 in French and held by 1 WorldCat member library worldwide

This paper presents and reports on the progress of the EVALDA/MEDIA project, focusing on the recording protocol of the reference dialogue corpus. The aim of this project is to define and test an evaluation methodology that assess and diagnose the contextsensitive understanding capability of spoken language dialogue systems. Systems from both academic organizations (CLIPS, IRIT, LIA, LIMSI, LORIA, VALORIA) and industrial sites (FRANCE TELECOM R et D, TELIP) will be evaluated. ELDA is the coordinator of the Technolangue/EVALDA multicampaign evaluation project, a national initiative sponsored by the French government, of which MEDIA is a sub-campaign. MEDIA began in January 2003. VECSYS provides the recording platform for the project

Analyse, modélisation et détection automatique des disfluences dans le dialogue oral spontané contraint le cas du contrôle aérien by Jean-Léon Mehdi Bouraoui( )

1 edition published in 2009 in French and held by 1 WorldCat member library worldwide

The disfluencies are a frequently occurring phenomenon in any spontaneous speech production; it consists of the interruption of the normal flow of speech. They have given rise to numerous studies in Natural Language Processing. Indeed, their study and precise identification are essential, both from a theoretical and applicative perspective. However, most of the researches about the subject relate to everyday uses of language: "small talk" dialogs, requests for schedule, speeches, etc. But what about spontaneous speech production made in a restrained framework? To our knowledge, no study has ever been carried out in this context. However, we know that using a "language specialty" in the framework of a given task leads to specific behaviours. Our thesis work is devoted to the linguistic and computational study of disfluencies within such a framework. These dialogs concern air traffic control, which entails both pragmatic and linguistic constraints. We carry out an exhaustive study of disfluencies phenomena in this context. At first we conduct a subtle analysis of these phenomena. Then we model them to a level of abstraction, which allows us to obtain the patterns corresponding to the different configurations observed. Finally we propose a methodology for automatic processing. It consists of several algorithms to identify the different phenomena, even in the absence of explicit markers. It is integrated into a system of automatic processing of speech. Eventually, the methodology is validated on a corpus of 400 sentences

Interaction tactile chez les personnes âgées by Guillaume Lepicard( )

1 edition published in 2012 in French and held by 1 WorldCat member library worldwide

The thesis aims to study the optimization of touch interaction for the elderly. It makes several contributions in four chapters. The first describe three states of the art: the first state of art talks about the age-related deficiencies such as motor skills and cognitive problems, but also deficiencies in the sense of vision, hearing and touch; the second describes touch screen technology with their history, their operation and a guide to choose the best one; and the third explains the needs and the contributions for gerontechnology based on touch screen. Chapters II and III have the same structure: a presentation of each test platform that we developed and tests associated with these platforms. Chapter II shows the impact, depending on the complexity of interface, of the use of both hands and the optimization of the interface for this use. It also shows, always depending on the complexity of interface, the contribution of an "invisible" interface and the learning effect of this one. The results are a longer completion time for the elderly than younger adults and a higher intake of spatialization. Chapter III presents the interest of using multi-touch interaction in object manipulation. Two preliminary studies were performed to calibrate the test. The experiment shows that the rotation and zoom are more difficult to achieve with multi-touch interaction for the elderly. Also, using a finger is more recommended than using two fingers for the elderly. In conclusion, these studies have helped to define design recommendations for better inclusion of the elderly. Different perspectives are also presented
