Analyse d'information tridimensionnelle issue de systèmes multi-caméras pour la détection de la chute et l'analyse de la marche by Edouard Auvinet( Book )

This thesis is concerned with defining new clinical investigation method to assess the impact of ageing on motricity. In particular, this thesis focuses on two main possible disturbance during ageing : the fall and walk impairment. This two motricity disturbances still remain unclear and their clinical analysis presents real scientist and technological challenges. In this thesis, we propose novel measuring methods usable in everyday life or in the walking clinic, with a minimum of technical constraints.In the first part, we address the problem of fall detection at home, which was widely discussed in previous years. In particular, we propose an approach to exploit the subject's volume, reconstructed from multiple calibrated cameras. These methods are generally very sensitive to occlusions that inevitably occur in the home and we therefore propose an original approach much more robust to these occultations. The efficiency and realtime operation has been validated on more than two dozen videos of falls and lures, with results approaching 100 % sensitivity and specificity with at least four or more cameras.In the second part, we go a little further in the exploitation of reconstructed volumes of a person at a particular motor task : the treadmill, in a clinical diagnostic. In this section we analyze more specifically the quality of walking. For this we develop the concept of using depth camera for the quantification of the spatial and temporal asymmetry of lower limb movement during walking. After detecting each step in time, this method makes a comparison of surfaces of each leg with its corresponding symmetric leg in the opposite step. The validation performed on a cohort of 20 subjects showed the viability of the approach
Analyse, modélisation et simulation de l'impulsion au sol dans les activités physiques by Carole Durocher( Book )

3 editions published between 2005 and 2007 in French and held by 3 WorldCat member libraries worldwide

The take-off is a preponderant time that influences performance. This work focuses on the indirect measurement of external forces applied on subjects thanks to motion capture. This measurement requires the use of body segments parameters that were obtained with the averaged data of different subjects. This work proposes a method to customise body segments parameters. External forces are evaluated and then, modelled with cubic splines capturing the shapes of the corresponding curves. The resulting control points enhance the comparison between the take-offs. Both methods are used to simulate new take-offs. This simulation is obtained by optimisation of the control points to verify new constraints and new performances. As a perspective, this work could lead to new approaches to optimise performance in take-off

Transport des enfants et locomotion : approche intégrative biomécanique et comparative chez l'humain et le primate non humain by Zohreh Anvari( Book )

2 editions published in 2013 in French and held by 2 WorldCat member libraries worldwide

In the past, the infant carrying could be a limiting factor for the mobility of pre-human and human groups. In order to better understand the infant carrying strategies of hominids, we developed a quantified study of the impact of infant carrying in two terrestrial locomotor models: the olive baboon (Papio anubis), as a quadrupedal model, and humans (Homo sapiens) as bipedal model. The analysis focuses on the sagital kinematics (joint angles, speed, position of the center of mass) and kinetic (ground reaction forces) of the unloaded and loaded walking of 11 female olive baboons living in captivity at the Station of Primatology (CNRS, France) and 26 Qachqai women, nomads living in a natural environment of the Fars province (Iran). Data were collected thanks to an integrated setup with a high speed video recording system, a force plate and individual anthropometry. The results demonstrate that several mechanisms exist that are related to the mode of carrying and the weight of the infant. As a result, in olive baboon, the global architecture of the female's body prevents increasing constraints on the forelimb that could be expected while carrying a load quadrupedally. In Qachqai women, lower limbs are less bent which help limiting energy expenditure related to infant carrying
Objectivation et standardisation des évaluations ergonomiques des postes de travail à partir de données Kinect by Pierre Plantard( Book )

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

L'analyse ergonomique des postes de travail reste le point de départ de toute politique de prévention des risques de maladies professionnelles. De nombreux travaux scientifiques s'attachent à quantifier les déterminants à risque pour aboutir le plus souvent à un score de pénibilité. La difficulté actuelle des méthodes de cotation ergonomique se situe au niveau de la capture de ces déterminants. La majorité des systèmes se limitent à une collecte de données souvent subjective et très influencé par la personne effectuant la cotation. La volonté de l'entreprise par le biais de ce stage est d'objectiver l'analyse ergonomique des postes de travail par une capture du mouvement de l'opérateur. Le principale défi est le passage d'outil et de méthode scientifique à une utilisation de terrain avec toutes les contraintes qu'elle induit. L'apport des avancées technologiques et scientifiques encourage ce passage par des outils utilisable dans le contexte industriel. Les deux principaux objectif de ce stage se sont situer premièrement sur la limitation des biais de capture pour amener un précision et un standardisation de la mesure de terrain, ainsi que sur l'accès à de nouvelles données notamment l'aspect temporel de la tâche effectuée. Le matériel utilisé est le capteur de profondeur Kinect développé par Microsoft. Cet appareil fait l'objet d'études scientifique dans différents domaines et plus particulièrement dans son utilisation pour de la capture de mouvements. Lors de ce stage, nous nous somme attaché à traiter le signal émis par la Kinect, pour obtenir des données permettant le remplissage automatique de grille de cotation. Le bruit de mesure fût travailler à l'aide d'un filtre récursif passe bas utilisé fréquemment en laboratoire d'analyse du mouvement. Le traitement des données spatiales brut des articulations de l'opérateur pour obtenir des angles fit l'objet d'un grande partie du travail, car ne nombreux paramètre entre en jeu comme la position du capteur. La réussite du stage à permis de limiter la subjectivité de la mesure mais à également donnée l'accès à de nouveaux indices comme les pourcentage de temps de cycle passé à des angulations dangereuses pour l'opérateur. Le passage d'outil de laboratoire au terrain mérite encore d'être travaillé notamment dans la robustesse des systèmes développés et doit s'appuyer sur des expérimentations de laboratoire
Analyse et simulation des mouvements optimaux en escalade by Simon Courtemanche( )

1 edition published in 2014 in English and held by 2 WorldCat member libraries worldwide

How optimal are human movements ? This thesis tackles this issue by focusing especially on climbing movements, studied here under three complementary aspects which are the experimental gathering of climbing sequences, the biomechanical analysis of these data, and the synthesis of gestures by timing optimization. Walking has been largely studied, with good results in animation [Mordatch 2013]. We are interested here especially in the original question of climbing motions, whose diversity and multicontact aspect present an interesting complexity for the evaluation of the human motion characteristics. The heterogeneity of climbing gestures can be linked to several factors which are the variety of wall shapes, the multiplicity of climber skill levels, and different climbing categories, namely bouldering, route climbing or speed climbing. Our exploratory approach of this sport consists in three steps: the data collection by multicamera marker-based motion capture, combined with a set of force sensors mounted on an in-laboratory bouldering wall; a gesture analysis by inverse dynamics, taking only kinematic data as inputs, based on the minimization of internal torques to resolve the multicontact ambiguity, intrinsic to the climbing activity, validated by comparison with sensor measurements; and finally, the use of the energy efficiency criterion for synthesizing the best timing associated with a given sequence of movements. Experimental recordings were made at McGill University which has a climbing wall instrumented of 6 force sensors, and a motion capture device of 24 cameras, which allowed us to collect data on a population of nine subjects. The analysis of these data is the second part of this thesis. The addressed challenge is to find the external forces and internal torques from the climber's movements only. To this end we assume an optimal distribution of internal torques. After analysis, the distribution turns out to be rather uniform than proportional to the muscle capacity associated to each body joint. Finally, in a third and last part, we focus on the timing of climbing gestures, taking as input the path of the climber, possibly after inverse kinematics in order to overcome the need for a capture with markers and infrared cameras. As output, an optimal timing for this path is found. This timing is realistic, but lacks of a modelization for hesitation and decision making instants, as well as a model for the contact establishment, with the associated temporal delay currently not taken into account

La réalité virtuelle pour l'analyse des duels sportifs : application au duel entre un gardien et un tireur au handball by Benoit Bideau( Book )

2 editions published in 2003 in French and held by 2 WorldCat member libraries worldwide

The comprehension of the sporting duels is a complex task, because it requires to control an interaction between two subjects. Under real conditions of play, it is impossible to control all the parameters. Thus no relation can be made between a movement and the response of the opponent. Virtual reality offers new prospects to make interact sportsmen in environments entirely under control. In this thesis, we propose to develop and validate a process for the analysis in sporting duels, in a precise application: the duel between a goalkeeper and a thrower in handball. First, we show that the reactions of the goalkeeper are identical, for the same throw, in a real and virtual environment. Once our tool is validated, we modify the gesture of the humanoid thrower thanks to a model of movement. This enables us to define the influence of the thrower's movements on the reaction of the goalkeeper. We quantify thus, the influence of the wrist, climbing the bust, and the modification of ball release on the goalkeeper's reaction
Analyse et synthèse de mouvements théâtraux expressifs. by Pamela Carreno Medrano( )

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

This thesis addresses the analysis and generation of expressive movements for virtual human characters. Based on previous results from three different research areas (perception of emotions and biological motion, automatic recognition of affect and computer character animation), a low-dimensional motion representation is proposed. This representation consists of the spatio-temporal trajectories of end-effectors (i.e., head, hands and feet) and pelvis. We have argued that this representation is both suitable and sufficient for characterizing the underlying expressive content in human motion and for controlling the generation of expressive whole-body movements. In order to prove these claims, this thesis proposes: i.) A new motion capture database inspired by physical theater theory. This database contains examples from different motion classes (i.e., periodic movements, functional behaviors, spontaneous motions, and theater-inspired motion sequences) and distinct emotional states (happiness, sadness, relaxedness, stress and neutral) performed by several actors. ii.) A user study and automatic classification framework de- signed to qualitatively and quantitatively assess the amount of emotion-related information conveyed and encoded in the proposed representation. We have observed that although slight differences in performance were found with respect to the cases in which the entire body was used, our proposed representation preserves most of the motion cues salient to the expression of affect and emotions. iii.) A simple motion synthesis system able to capable of: a) reconstructing whole-body movements from the proposed low-dimensional representation, and b) producing novel end- effector (and pelvis) expressive trajectories. A quantitative and qualitative evaluation of the generated whole body motions shows that these motions are as expressive as the movements recorded from human actors
Gestion de la variabilité morphologique pour la reconnaissance de gestes naturels à partir de données 3D by Anthony Sorel( Book )

2 editions published in 2012 in French and held by 2 WorldCat member libraries worldwide

Recognition of natural movements is of utmost importance in the implementation of intelligent and effective Human-Machine Interfaces for virtual environments. It allows the user to behave naturally and the system to recognize its body movements in the same way a human might perceive it. This task is complex, because it addresses several challenges : take account of the specificities of the motion capture system, manage kinematic variability in motion performance, and finally take account of the morphological differences between individuals, so that actions of any new user can be recognized. Moreover, due to the interactive nature of virtual environments, this recognition must be achieved in real-time without waiting for the motion end. The literature offers many methods to meet the first two challenges. But the management of the morphological variability is not dealt. In this thesis, we propose a description of the movement to address this issue and we evaluate its ability to recognize the movements of an unknown user. Finally, we propose a new method to take advantage of this representation in early motion recognition
Le mouvement segmentaire au service du déplacement dans la marche : analyse couplée des deux niveaux by Antoine Marin( Book )

2 editions published in 2014 in French and held by 2 WorldCat member libraries worldwide

Walking is a complex mecanism involving trajectories generation in various environments and motion generation in order to follow the path. Then, it is dependent on environment, obstacles and peoples moving around but also on body capabilities. This complexity lead scientits to split walking analysis in two levels : trajectory generation in one hand, and motion generation in the othe hand. This work aim to provide a global walking analysis processus by linking trajectorires and motion generation. First, we explore walking trajectories throw a particular situation : pedestrians crossing. Here we take interest in trajectories and speed adaptations. Then, we sink for the link between trajectory and heelstrike. It lead us to develop a model for heelstrike generation based on trajectory. Finally, we take interest in walking motion simulation. By the use of local linearization, we provide a new methodology for joints joints angles generation
On the Relevance of Using Virtual Humans for Motor Skills Teaching : a case study on Karate gestures by Anne-Marie Burns( Book )

2 editions published in 2013 in English and held by 2 WorldCat member libraries worldwide

The main question of that thesis is on the relevance of using virtual humans to teach complex motor skills. The first study explores the question of the feasibility of learning by imitation of a virtual human by comparing the improvement of the performance on three karate gestures for three groups, namely a traditional class, a video-based group and a virtual reality group. The second study investigates the influence on the learning task of having a self representation in the virtual environment. The participants have a feedback of their movements represented on a mirrored cylindrical gray avatar. The impact of that avatar on the learning task of the participants is assessed by two means. Performance evaluations are performed and give an external perspective on the learning. Evocation interview are also performed to get an insight of the learning task from the participants point of view. Finally, these two studies are completed by a third one investigating the possibility to have an automatic performance evaluator in order to reduce grading discrepancies generated by humans graders. Such a tool would be required to have an objective performance evaluation of all the participants in order to compare the four learning environments presented in that thesis and eventual further iteration of these environments. The conclusion our the studies presented in that thesis are that learning motor skills from the imitation of a virtual human is possible. Consequently, virtual learning environments for motorskills teaching are relevant. Furthermore, these environments can be used in various types of applications. They can be used as a study tool for standard and controlled investigation of teaching by demonstration. They can also be used in an engineering loop for the development of further learning environments and training accelerators. They also have a potential usage in the development of exergames in response to the international obesity crisis
Etude de la gestion et du contrôle de l'inertie lors de la réalisation d'une tâche acrobatique complexe en gymnastique by Aurore Huchez( )

1 edition published in 2013 in French and held by 1 WorldCat member library worldwide

Si de nombreuses études ont été consacrées à l'analyse des grands tours préparatoires aux sorties, aux sorties elles-mêmes et aux lâchers de barre en barre fixe ou barre supérieure de barres asymétriques, les éléments avec envol pour passer d'une barre à l'autre aux barres asymétriques (lâcher la barre inférieure pour saisir la barre supérieure ou l'inverse) n'ont, à notre connaissance, pas fait l'objet de telles études. Cette thèse de doctorat présente dans sa première partie une analyse cinématique du « pieds barre temps de ventre » ainsi qu'une analyse des moments cinétique et d'inertie mis en jeu par deux groupes de gymnastes, des expertes et des novices, lors de la réalisation de ce mouvement. La deuxième partie met en évidence des lois de contrôle moteur utilisées par les deux groupes pour réaliser l'élément. Afin de déterminer si les mouvements des deux groupes sont susceptibles d'améliorations et si la trajectoire créée au lâcher de la barre inférieure ou la gestuelle mise en jeu influence davantage la performance, une optimisation du pieds barre temps de ventre est proposée dans la troisième partie. Enfin, l'effet de l'introduction d'une loi de contrôle moteur dans le processus d'optimisation sur le réalisme des mouvements optimisés est envisagé
Adaptation dynamique de mouvements humains by Ludovic Hoyet( Book )

2 editions published in 2010 in French and held by 1 WorldCat member library worldwide

In computer animation, the goal is to simulate human behavior to create virtual humans as realistic as possible. One important key point in this realism is to respect the laws of the dynamic. This PhD thesis deals with understanding the dynamics of virtual human motion and modeling simplified dynamics to reach interactive applications. In a first study about measuring dynamic balance, we evaluated the efficiency and the utilization range of various criteria for dynamic balance. Then, we studied the accuracy of users to differentiate the mass of a dumbbell lifted either by a real or a virtual human. Results show that users do not manage to differentiate small mass differences. However, they did not presented significant differences between comparing real videos or virtual animations. Regarding the accuracy reached by users on the perception of dynamic constraints, we proposed a new perception-based method for dynamic adaptation of human motions subject to new external constraints
