Full textWe study a brain computer interface (BCI) to control a prosthesis with thought. The aim of the BCI is to decode the movement desired by the subject from electroencephalographic (EEG) signals. The core of the BCI is a classification algorithm characterized by the choice of signals descriptors and decision rules. The purpose of this thesis is to develop an accurate BCI system, able to improve its performance during its use and to adapt to the user evolutions without requiring multiple learning sessions. We combine two ways to achieve this. The first one is to increase the precision of the decision system by looking for relevant descriptors for the classification. The second one is to include a feedback to the user on the system decision : the idea is to estimate the error of the BCI from evoked brain poten tials, reflecting the emotional state of the patient correlated to the success or failure of the decision taken by the BCI, and to correct the decision system of the BCI accordingly. The main contributions are : we have proposed a method to optimize the feature space based on wavelets for multi-channel EEG signals ; we quantified theoretically the performances of the complete system improved by the detector ; a simulator of the corrected and looped system has been developed to observe the behavior of the overall system and to compare different strategies to update the learning set ; the complete system has been implemented and works online in real conditions

Full textLes informations disponibles sur l'Internet se développent à un rythme tel que bientôt les méthodes de recherche textuelle utilisant la fréquence des termes ne seront plus suffisantes. Un courant de pensée est consacré à la personnalisation de la recherche, à savoir prendre en compte des traits spécifiques et le contexte de l’utilisateur pour répondre à sa requête. Nous pensons que le profil, la communauté, et le contexte de l'utilisateur sont les trois concepts essentiels à envisager pour faire face au problème de la croissance du World Wide Web. La thèse étudie la combinaison de ces trois courants de pensée. Dans la première partie de cette thèse, nous développons un système de recherche d’information personnalisé et collaboratif (appelé PERCIRS), qui utilise les deux premiers concepts (le profil et la communauté). PERCIRS crée une liste classée de documents pertinents, pour la requête q de l'utilisateur U. Cette classification se fait sur la base des documents sélectionnés pour les requêtes semblables à q par les utilisateurs au profil similaire à celui de U. Le choix de la méthode de recherche d’utilisateurs similaires joue un rôle important dans l’efficacité de PER-CIRS. À cette fin, nous avons proposé trois catégories de formules pour calculer la similarité entre deux profils d'utilisateurs: formule fondée sur l'égalité, formule fondée sur la similarité et enfin une formule fondée sur les graphes. Afin de trouver la catégorie optimale, nous avons proposé deux mécanismes d'évaluation: fondés sur les concepts de la catégorisation et de la classification. Ces deux mécanismes s’appuient sur les formules de calcul de profil utilisateur fondées sur les graphes. PERCIRS étant un système de recherche d’information (SRI) personnalisé (en raison de la prise en compte des profils d'utilisateur), il ne peut pas être évalué par des mécanismes d'évaluation tels que Cranfield (par exemple TREC). Par conséquent, dans cette thèse, nous proposons un nouveau mécanisme qui permet de l'évaluer en même temps que les autres SRI classiques tels que BM25 – Okapi. Dans la deuxième partie de ce travail de thèse,, le contexte de l'utilisateur est utilisé pour adapter, aux préférences de l'utilisateur, un document trouvé par PERCIRS. Nous proposons d'adapter physiquement et sémantiquement un document selon le profil de l'utilisateur et selon le profil de contexte. Un mécanisme est également proposé pour naviguer dans des documents adaptés en fonction des préférences de l'utilisateur

Full textUser interfaces adaptation by using emotions.Perso2U, an approach to personalize user interfaces with user emotions.User experience (UX) is nowadays recognized as an important quality factor to make systems or software successful in terms of user take-up and frequency of usage. UX depends on dimensions like emotion, aesthetics or visual appearance, identification, stimulation, meaning/value or even fun, enjoyment, pleasure, or flow. Among these dimensions, the importance of usability and aesthetics is recognized. So, both of them need to be considered while designing user interfaces (UI).It raises the question how designers can check UX at runtime and improve it if necessary. To achieve a good UI quality in any context of use (i.e. user, platform and environment), plasticity proposes to adapt UI to the context while preserving user-centered properties. In a similar way, our goal is to preserve or improve UX at runtime, by proposing UI adaptations. Adaptations can concern aesthetics or usability. They can be triggered by the detection of specific emotion, that can express a problem with the UI.So the research question addressed in this PhD is how to drive UI adaptation with a model of the user based on emotions and user characteristics (age & gender) to check or improve UX if necessary.Our approach aims to personalize user interfaces with user emotions at run-time. An architecture, Perso2U, has been designed to adapt the UI according to emotions and user characteristics (age and gender). Perso2U includes three main components: (1) Inferring Engine, (2) Adaptation Engine and (3) Interactive System. First, the inferring engine recognizes the user’s situation and in particular him/her emotions (happiness, anger, disgust, sadness, surprise, fear, contempt) plus neutral which are into Ekman emotion model. Second, after emotion recognition, the best suitable UI structure is chosen and the set of UI parameters (audio, Font-size, Widgets, UI layout, etc.) is computed based on such detected emotions. Third, this computation of a suitable UI structure and parameters allows the UI to execute run-time changes aiming to provide a better UI. Since the emotion recognition is performed cyclically then it allows UI adaptation at run-time.To go further into the inferring engine examination, we run two experiments about the (1) genericity of the inferring engine and (2) UI influence on detected emotions regarding age and gender.Since this approach relies on emotion recognition tools, we run an experiment to study the similarity of detecting emotions from faces to understand whether this detection is independent from the emotion recognition tool or not. The results confirmed that the emotions detected by the tools provide similar emotion values with a high emotion detection similarity.As UX depends on user interaction quality factors like aesthetics and usability, and on individual characteristics such as age and gender, we run a second experimental analysis. It tends to show that: (1) UI quality factors (aesthetics and/or usability) influences user emotions differently based on age and gender, (2) the level (high and/or low) of UI quality factors seem to impact emotions differently based on age and gender. From these results, we define thresholds based on age and gender that allow the inferring engine to detect usability and/or aesthetics problems

Full textThis thesis criticizes, from a psychological point of view, the kind of assistance provided by current help systems to casual users of computing devices. The criticism turns on the appropriateness of the reference model (i. E. The representation of the knowledge acquired or to be acquired by the user) used by those systems for interpreting user's actions and for defining the assistance they need. The reference model generally used in current help systems is mainly some expert model. The thesis shows, from a psychological analysis of the activity of some casual programmers, the inappropriateness of the expert model for interpreting the behavior of this category of users. Likewise the thesis shows the inappropriateness of the expert model for defining the assistance that meets casual users'needs and expectations. In fact, the use of some expert model implies that casual users, like experts, attempt to achieve some optimal solution (optimization principle) whereas they attempt to achieve some satisficing solution more often (operationalization principle), by elaborating sub-optimal plans. Thereby they cannot exploit helps and solutions given in terms of the expert model, because they are too far from their representation of the problem. Thus the thesis suggests to design systems that help casual programmers to realize their sub-optimal plans (help to operationalization). More generally, it is suggested to provide help systems with a reference model that is stereotypical of the category of users to whom the help is adressed

Full textWith the network heterogeneity and increasing demand of multimedia services, Quality of Experience (QoE) becomes a crucial determinant of the success or failure of these services. In this thesis, we first propose to analyze the impact of quality metrics on user engagement, in order to understand the effects of video metrics (video startup time, average bitrate, buffering ratio) and content popularity on user engagement. Our results show that video buffering and content popularity are critical parameters which strongly impacts the end-user’s satisfaction and user engagement, while the video startup time appears as less significant. On other hand, we consider subjective approaches such as the Mean Opinion Score (MOS) for evaluating QoE, in which users are required to give their assessment according to contextual information. A detailed statistical analysis of our study shows the existence of non-trivial parameters impacting MOS (the type of device and the content type). We propose mathematical models to develop functional relationships between the QoE and the context information which in turn permits us to estimate the QoE. A video content optimization technique called MDASH (for MOS Dynamic Adaptive Streaming over HTTP) is proposed, which improves the perceived QoE for different video sessions sharing the same local network, while taking QoE fairness among users as a leitmotiv. We also propose a utility-based approach for video delivery optimization, in which a global utility function is computed based on different constraints (e.g. target strategies coming from the actors of the delivery chain)
