CETTE THESE PRESENTE L'ETUDE DE LA MODELISATION DES INTERACTIONS QUI SURVIENNENT LORSQUE PLUSIEURS ROBOTS MOBILES, EQUIPES DE SENSEURS VISUELS, PARTAGENT UN MEME ENVIRONNEMENT. DANS UN PREMIER TEMPS, LA MODELISATION DES CAPACITES MOTRICES ET SENSORIELLES D'UN ROBOT MOBILE EST ENVISAGEE. LE CONCEPT DE CARTE DYNAMIQUE EST AINSI INTRODUIT POUR REPRESENTER DE FACON GEOMETRIQUE LA MOBILITE DU ROBOT DANS SON ENVIRONNEMENT. CE CONCEPT EST BASE SUR LA THEORIE DES REGIONS ATTEIGNABLES D'UN SYSTEME DYNAMIQUE. LES METHODES DE CONSTRUCTION DES CARTES DYNAMIQUES DE PLUSIEURS TYPES DE ROBOT MOBILE SONT DECRITES, AINSI QU'UN ALGORITHME D'APPRENTISSAGE DE LA CARTE D'UN ROBOT PAR LUI-MEME. LA RELATION INTIME EXISTANT ENTRE LA CAMERA DU ROBOT ET SES CAPACITES DE DEPLACEMENT EST EGALEMENT EXPLOREE AU TRAVERS DU CONCEPT DE CARTE DYNAMIQUE. DANS UN DEUXIEME TEMPS, LE CONCEPT DE CARTE DYNAMIQUE EST UTILISE POUR GENERER UNE REPRESENTATION DES INTERACTIONS ENTRE LES ROBOTS MOBILES. AINSI, A PARTIR DES CONDITIONS D'ENVIRONNEMENTALES ET DES POSITIONS RELATIVES DES ROBOTS RECUPEREES PAR LE SENSEUR DU ROBOT, LA CARTE DU ROBOT APPRISE ET LES CARTES DYNAMIQUES DES AUTRES ROBOTS ESTIMEES SONT COMBINEES. CETTE COMBINAISON PERMET DE FAIRE APPARAITRE LA DISTRIBUTION DE L'ESPACE ATTEIGNABLE DU ROBOT EN FONCTION NON SEULEMENT DE SES CAPACITES MAIS EGALEMENT DE CELLES DES AUTRES ROBOTS DANS LE CADRE D'UNE TACHE A ACCOMPLIR EN COOPERATION OU EN COMPETITION. CETTE REPRESENTATION EST UTILISEE PAR LA SUITE POUR PERMETTRE LA PLANIFICATION D'UNE TRAJECTOIRE D'EVASION POUR UN ROBOT POURSUIVI ET PRESENTE. LES ECHECS ET LES REUSSITES D'UN SYSTEME D'APPRENTISSAGE D'UNE STRATEGIE DE POURSUITE PAR RENFORCEMENT ONT PERMIS DE PROUVER L'UTILISTE DE LA CARTE DYNAMIQUE COMME UN OUTIL D'ANALYSE DES INTERACTIONS ENTRE ROBOTS. UN BANC D'ESSAI EXPERIMENTAL BASE SUR DES ROBOTS RADIOGUIDES A ETE DEVELOPPE AFIN DE METTRE EN PRATIQUE DANS LE FUTUR LES CONCEPTS DECRITS DANS LE CADRE DE CETTE THESE. LES VEHICULES UTILISES NE POSSEDANT PAS D'ODOMETRIE INTERNE, LA CONCEPTION ET LA REALISATION D'UN SYSTEME D'ODOMETRIE SIMULEE A ETE NECESSAIRE
To give mobile robots real autonomy, and to permit them to act efficiently in a diverse, cluttered, and changing environment, they must be equipped with powerful tools for perception and reasoning. Artificial Vision for Mobile Robots presents new theoretical and practical tools useful for providing mobile robots with artificial vision in three dimensions, including passive binocular and trinocular stereo vision, local and global 3D map reconstructions, fusion of local 3D maps into a global 3D map, 3D navigation, control of uncertainty, and strategies of perception. Numerous examples from research carried out at INRIA with the Esprit Depth and Motion Analysis project are presented in a clear and concise manner. Nicolas Ayache is Research Director at INRIA, Le Chesnay, France. Contents. General Introduction. Stereo Vision. Introduction. Calibration. Image Representation. Binocular Stereo Vision Constraints. Binocular Stereo Vision Algorithms. Experiments in Binocular Stereo Vision. Trinocular Stereo Vision, Outlook. Multisensory Perception. Introduction. A Unified Formalism. Geometric Representation.

User Experience Innovation is a book about creating novel and engaging user experiences for new products and systems. User experience is what makes devices such as Apple's iPhone and systems such as Amazon.com so successful. iPhone customers don't buy just a phone; they buy into an experience enabled by the device. Similarly, Amazon.com customers enter a world of book reviews, interesting recommendations, instant downloads to their Kindle, and one-click purchasing. Products today are focal points, and it is the experience surrounding the product that matters the most. User Experience Innovation helps you create the right sort of experience around your products in order to be successful in the marketplace. The approach in User Experience Innovation is backed by 18 years of experience from an author holding more than 100 patents relating to user experience. This is a book written by a practitioner for other practitioners. You'll learn 17 specific methods for creating innovation; these methods run the gamut from targeting user needs to relieving pain points, to providing positive surprises, to innovating around paradoxes. Each method is one that the author has used successfully. Taken together, they can help you create truly successful user experience innovations to benefit your company or organization, and to help you grow as an experienced expert and innovator in your own right. Provides 17 proven methods for innovating around user experience Helps you think beyond the product to the sum total of a customer's experience Written by an experienced practitioner holding more than 100 user-experience patents
The Routledge Encyclopedia of Interpreting Studies is the authoritative reference for anyone with an academic or professional interest in interpreting. Drawing on the expertise of an international team of specialist contributors, this single-volume reference presents the state of the art in interpreting studies in a much more fine-grained matrix of entries than has ever been seen before. For the first time all key issues and concepts in interpreting studies are brought together and covered systematically and in a structured and accessible format. With all entries alphabetically arranged, extensively cross-referenced and including suggestions for further reading, this text combines clarity with scholarly accuracy and depth, defining and discussing key terms in context to ensure maximum understanding and ease of use. Practical and unique, this Encyclopedia of Interpreting Studies presents a genuinely comprehensive overview of the fast growing and increasingly diverse field of interpreting studies.

The craft of gesture is part of the practical equipment with which we inhabit and understand the world together. Drawing on micro-ethnographic research in diverse interaction settings, this book explores the communicative ecologies in which hand-gestures appear: illuminating the world around us, depicting it, making sense of it, and symbolizing the interaction process itself. Gesture is analyzed as embodied communicative action grounded in the hands' practical and cognitive engagments with material worlds. The book responds to the quest for the role of the human body in cognition and interaction with an analytic perspective informed by phenomenology, conversation analysis, context analysis, praxeology, and cognitive science. Many of the cross-linguistic video-data of everyday interaction investigated in its chapters are available on-line.
Here, Jay Ruby—a founder of visual anthropology—distills his thirty-year exploration of the relationship of film and anthropology. Spurred by a conviction that the ideal of an anthropological cinema has not even remotely begun to be realized, Ruby argues that ethnographic filmmakers should generate a set of critical standards analogous to those for written ethnographies. Cinematic artistry and the desire to entertain, he argues, can eclipse the original intention, which is to provide an anthropological representation of the subjects. The book begins with analyses of key filmmakers (Robert Flaherty, Robert Garner, and Tim Asch) who have striven to generate profound statements about human behavior on film. Ruby then discusses the idea of research film, Eric Michaels and indigenous media, the ethics of representation, the nature of ethnography, anthropological knowledge, and film and lays the groundwork for a critical approach to the field that borrows selectively from film, communication, media, and cultural studies. Witty and original, yet intensely theoretical, this collection is a major contribution to the field of visual anthropology.
This book introduces the companion modelling approach by presenting the stance that underpins it, the methods and tools used with stakeholders and the specific role of models during the process. It addresses the means to deal with the different levels of decision-making and to take into account the various power relationships. It proposes a methodology to assess the impact of the approach on the stakeholders involved in the process. The book includes 27 case studies and 7 teaching tools that describe the successful use of the approach in a variety of settings or teaching contexts. It is intended for researchers working on rural development or renewable resources management, as well as students and teachers.
