This paper presents a user-centered approach for the design/re-design of a mobile application for chronic pain management, with a focus on chronic low back pain, sometimes referred to as "invisible disability". Within the framework of a multidisciplinary project involving physicians, patients and computer scientists, the work presented here describes firstly an identification and representation process of the needs/expectations of the users of such an application (patients/physicians), based on a data-driven persona development method and, secondly, an evaluation process of the user experience (UX) of the current version of the application, using among others usability tests. The aim of the approach is to establish (re-)design guidelines in order to improve this kind of application.

International audience; Background: The aim of our study was to conduct an ad hoc data collection in healthy adults with the intention of extracting individual profiles to study the ability to effectively monitor one's health by extracting relevant indicators. As “each patient is a unique case”, AMISIA (Defi CNRS AUTON project) proposes an integrated approach, combining medical health devices, information technology, and human factors to provide patients, health care actors and family caregivers with both the best incentives and a high degree of monitoring.Method: We conducted a data collection experiment in Limoges with 61 participants at the Limoges University. Data were biographic elements, socio-economic profiles, cognitive performance (Corsi test results), a psychological battery (anxiety, fatigue, sleep), posture and gait measurement with 4 Imus and a Wii-balance board, and finally physical activity during a week at home (Armband sensors).Results: For the Corsi virtual walking test, the median memory span for Group A was significantly less (p

Providing high-quality courses is of utmost importance to drive successful learning. This compels course authors to continuously review their contents to meet learners’ needs. However, it is challenging for them to detect the reading barriers that learners face with content, and to identify how their courses can be improved accordingly. In this paper, we propose a learning analytics approach for assisting course authors performing these tasks. Using logs of learners’ activity, a set of indicators related to course reading activity are computed and used to detect issues and to suggest content revisions. The results are presented to authors through CoReaDa, a learning dashboard empowered with assistive features. We instantiate our proposals using the logs of a major European e-learning platform, and validate them through a study. Study results show the effectiveness of our approach providing authors with more awareness and guidance in improving their courses, to better suit learners’ requirements.

This article deals with knowledge extracted from observed usages of Web sites/applications for assistance purposes. The extracted knowledge is used to develop assistance systems in order to help a) users in carrying out Web browsing tasks, or b) designers to adapt/redesign Web applications. The suggested approach involves the generation of task models from interaction traces, which are then used to perform assistance. Task metamodel characteristics for assistance purposes are firstly identified and then used to develop a comparative study of some well-known task metamodels, resulting in the selection of the ConcurTaskTrees (CTT) metamodel. In order to generate CTT task models, a set of algorithms that identify CTT operators from interaction traces - represented as deterministic finite state automata - are presented. We also expose an approach for performing assistance, for users and designers, based on task models and finally conducted unit testing and validation based on two real web browsing scenarios.

This work focuses on the extraction of knowledge from observed usage. More specifically, it aims to design a Web browsing assistance system that helps the user in carrying out his browsing task, or the designer in adapting or redesigning his Web application, according to real usage. The proposed approach consists of generating task models from interaction traces, which are then used to perform assistance. The characteristics to be supported by a task metamodel for assistance purposes are first identified and then confronted with the characteristics of existing task metamodels. This first study led us to choose the ConcurTaskTrees (CTT) metamodel. We then developed processes to generate CTT task models from traces. Finally, to validate our approach, we conducted unit testing and validation based on two real web browsing scenarios.

Until recently, propositions on the subject of intelligent service companions, like robots, were mostly user and environment independent. Our work is part of the FUI-RoboPopuli project, which concentrates on endowing entertainment companion robots with adaptive and social behavior. More precisely, we focus on the capacity of an intelligent system to learn how to personalize and adapt its behavior/actions according to its interaction situation that describes (a) the current user attributes, and (b) the current environment attributes. Our approach is based on models of the type of Markov decision processes (MDPs) that are largely used for adaptive robot applications. In order to have, as quickly as possible, a relevant adaptive behavior whatever the interaction situation, several approaches were proposed to decrease the sample complexity required to learn the MDP model, including its reward function. We argue that systems that are based on detecting important attributes for each decision are more likely to converge faster than others. To this end, we present two algorithms to learn the MDP reward function through analyzing interaction traces (i.e., the interaction history between the robot and its users including their feedback regarding the robot actions). The first algorithm is direct, certain and does not particularly exploit its knowledge to adapt to unknown situations (i.e., unknown users’ and/or environment settings). The second is able to detect the importance of certain situation attributes in the adaptation process. The detection of important attributes is used to speed up the learning process and helps by generalizing the learned reward function to unknown situations. In this paper, we present both learning algorithms, simulated experiments and an experiment with the EMOX (EMOtion eXchange) robot that was upgraded during the FUI-RoboPopuli project. The results of those experiments prove that when dealing with adaptive decision making, the detection of important attributes for each decision speeds up the learning process and help in achieving convergence using fewer samples. We also present a scaling analysis through the simulated experiments.

International audience; A challenge that course authors face when reviewing their contents is to detect how to improve their courses in order to meet the expectations of their learners. rnIn this paper, we propose an analytical approach that exploits learners' logs of reading to provide authors with insightful data about the consumption of their courses. rnWe first model reading activity using the concept of reading-session and propose a new and efficient session identification. We then elaborate a list of indicators computed using learners' reading sessions that allow to represent their behaviour and to infer their needs. We evaluate our proposals with course authors and learners using logs from a major e-learning platform. Interesting results were found. This demonstrates the effectiveness of the approach in identifying aspects and parts of a course that may prevent it from being easily read and understood, and for guiding the authors through the analysis and review tasks.

International audience; For this paper, in the context of the French research project Spectacle en Ligne(s), we have recorded the entire set of rehearsals of one theater and one opera production using state-of-the-art video equipment. The resulting raw video and audio tracks as well as manually generated annotation data were then preprocessed in order to localize actors and detect their dialogues. Based on these preprocessing steps, we have built a Web-based hypervideo application that allows for navigation through performance time, performance space, and rehearsal time using modern HTML5 Web technologies like the emerging Web Components standard. We publish and consume the annotation data as so-called Linked Data Fragments, a novel way to make triple-based structured data available in a scalable way. As a direct outcome, researchers interested in the genetic analysis and the creation process of live performances can, thanks to this application, freely zoom in and out of scenes, rehearsal sessions, and stage locations in order to better understand the different steps on the way to a chef d'oeuvre. A live demo of the application is publicly available at the URL http://spectacleenlignes.fr/hypervideo/.

International audience; Adaptive and personalized behavior is becoming essential and desirable in Human-Robot Interactive systems. We are interested in adaptive robots that learn from interaction traces (previous interactions with users). Our proposal is based on types of interactions where users express their level of satisfaction through feedback. Indeed, depending on the situation of interaction and the user himself, the robot behavior should adjust, and therefore can be judged, differently. From interaction traces (including robot actions and users' feedback), we aim to extract \textit{adaptation rules} that give the dependencies between certain attributes of the interaction situation and/or the user profile, and the level of user satisfaction. We propose two learning algorithms to learn these adaptation rules. The first algorithm is direct, certain and optimal but slow to converge. The second is able to detect the importance of certain attributes in the adaptation process. It generalizes adaptation rules on unknown situations and to first time users, which makes it an approach with risk. We detail in this paper, our proposed model, both learning algorithms, and an evaluation of the learned rules from both algorithms by simulations and through a scenario with real users.

Session 2 : Utilisateurs et usages; National audience; Dans le cadre des systèmes adaptatifs, notre travail de recherche porte sur l'acquisition des connaissances d'adaptation à partir des traces d'interaction laissées par les utilisateurs. Les traces contiennent, entre autres, les feedbacks, positifs ou négatifs, des utilisateurs par rapport aux actions du système. Notre objectif est de définir des modèles et des outils permettant d'extraire des règles d'adaptation que le système pourra utiliser, dans son processus de décision, afin de personnaliser son comportement à l'utilisateur. Ces règles d'adaptation établissent des relations de dépendance entre certaines caractéristiques du contexte d'interaction (à savoir certains attributs de la situation d'interaction, tels que le lieu, la luminosité, etc. et/ou du profil de l'utilisateur) et le niveau de satisfaction de l'utilisateur. Pour cela, nous proposons deux algorithmes d'apprentissage. Le premier est direct est certain, dans le sens où toutes les règles générées correspondent à des contextes d'interaction déjà rencontrés par le système, mais nécessite un nombre important de traces pour converger. Le deuxième est plus rapide mais présente des risques d'erreur. En effet, cet algorithme permet de généraliser les règles d'adaptation existantes à de nouveaux contextes d'interaction (i.e. de nouvelles situations et/ou nouveaux profils d'utilisateurs). Dans cet article, nous détaillons les modèles que nous proposons pour représenter les règles d'adaptation et les traces d'interaction ainsi que les deux algorithmes d'apprentissage. Nous présentons également les évaluations que nous avons menées, par simulation et avec de vrais utilisateurs, pour valider nos contributions.

International audience; We focus on the problem of adaptivity of companion robots to their users. Until recently, propositions on the subject of intelligent service robots were mostly user independent. Our work is part of the FUI-RoboPopuli project, which concentrates on endowing entertainment companion robots with adaptive and social behaviour. We concentrate on the capacity of robots to learn how to adapt and personalize their behaviour according to their users. Markov Decision Processes (MDPs) are largely used for adaptive robots applications. Several approaches were proposed to decrease the sample complexity to learn the MDP model, including the reward function. We proposed in previous work, two learning algorithms to learn the MDP reward function through analysing interaction traces (i.e. the interaction history between the robot and their users) including users' feedback. The first algorithm is direct and certain. The second is able to detect the importance of certain information, regarding the users (profiles) and/or the environment, in the adaptation process. We present, in this paper, a user study in addition to simulated experiments. Those experiments prove that our proposed algorithms are able to learn, through interactions with real users, a reward function that leads to an adapted and personalised robot behaviour. We also show the ability of our algorithms to handle exceptions and ambiguities in users feedback during experiments with real users.

International audience; Service robots have become increasingly important subjects in our lives. However, they are still facing problems like adaptability to their users. While major work has focused on intelligent service robots, the proposed approaches were mostly user independent. Our work is part of the FUI-RoboPopuli project, which concentrates on endowing entertainment companion robots with adaptive and social behaviour. In particular, we are interested in robots that are able to learn and plan so that they adapt and personalize their behaviour according to their users. Markov Decision Processes (MDPs) are largely used for adaptive robots applications. However, one challenging point is reducing the sample complexity required to learn an MDP model, including the reward function. In this article, we present our contribution regarding the representation and the learning of the reward function through analysing interaction traces (i.e. the interaction history between the robot and their users, including users' feedback). Our approach permits to generalise the learned rewards so that when new users are introduced, the robot may quickly adapt using what it learned from previous experiences with other users. We propose, in this article, two algorithms to learn the reward function. The first is direct and certain; the robot applies with a user what it learned during interaction with same kind of users (i.e. users with similar profiles). The second algorithm generalises what it learns to be applied to all kinds of users. Through simulation, we show that the generalised algorithm converges to an optimal reward function with less than half the samples needed by the direct algorithm.

International audience; Classical audiodescription process for improving video accessibility sometimes finds its limits. Depending on the video, required descriptions can be omitted because these may not fit in the durations of "gaps" in the video soundtrack (i.e. "void" spaces between dialogues or important sound elements). To address this issue, we present an exploratory work that focuses on the usage of "artificial" pauses in audio-described videos. Such pauses occur during the playing of the video so as to transmit more audio-descriptions. Our results show artificial pauses offer a good acceptability level as well as a low disturbing effect.

Document usages (i.e. usage feedbacks) cover readers' explicit annotations and their reading traces. We first describe a conceptual framework with various levels of assistance for document reengineering: indications on reading, problem detection, reconception suggestions and automatic reconception propositions, taking our example in e-learning document management. We then present a technical framework for usage-based document reengineering and its associated models for documents, annotations and traces representation.

International audience; Videos are commonly being augmented with additional content such as captions, images, audio, hyperlinks, etc., which are rendered while the video is being played. We call the result of this rendering “enriched videos”. This article details an annotationbased approach for producing enriched videos: enrichment is mainly composed of textual annotations associated to temporal parts of the video that are rendered while playing it. The key notion of enriched video and associated concepts is first introduced and we second expose the models we have developed for annotating videos and for presenting annotations during the playing of the videos. Finally, an overview of a general workflow for producing/viewing enriched videos is presented. This workflow particularly illustrates the usage of the proposed models in order to improve the accessibility of videos for sensory disabled people.

For this purpose, additional descriptions of key visual/audio information of the video, that cannot be perceived, are presented using accessible output modalities. However, a personalization mechanism is necessary to adapt these descriptions and their presentations according to user interests, cognitive and physical capabilities. In this article, concepts needed for this kind of personalization are introduced and an adaptive personalization mechanism of descriptions and associated presentations is suggested and evaluated.

International audience; Personalization of user interfaces for browsing content is a key concept to ensure content accessibility. This personalization is especially needed for people with disabilities (e.g,. visually impaired) and/or for highly mobile individuals (driving, off-screen environments) and/or for people with limited devices (PDAs, mobile phones, etc.). In this direction, we introduce mechanisms, based on a user requirements study, that result in the generation of personalized user interfaces for browsing particular XML content types. These on-the-fly generated user interfaces can use several modalities for increasing communication possibilities: in this way, interactions between the user and the system can take place in a more natural manner.

International audience; Thanks to the WAI (Web Accessibility Initiative) guidelines for producing accessible HTML documents, visually impaired people can have better access to a lot of textual information. Concerning musical score, several encoding formats are available, focusing on the representation of different aspects of this kind of content. As XML is the standard for exchanging content through the Web, several XML applications have already been specified for representing musical scores, using the traditional music notation. As a result, users can access and share a lot of different types of musical content using the Web. However, for specific notations – like the Braille one - no dedicated XML application has been developed yet. Therefore, visually impaired musicians cannot easily represent, share, and access scores using the Web. This paper presents the application we have developed to respond to this need: BMML (Braille Music Markup Language). BMML handles specificities of Braille Music notation and takes into account the core features of existing formats. The main objective of BMML is to improve the accessibility of Braille musical scores.
