Abstract

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.

Abstract

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.

Abstract

International audience; Preserving the cultural heritage of the performing arts raises difficult and sensitive issues, as each performance is unique by nature and the juxtaposition between the performers and the audience cannot be easily recorded. In this paper, we report on an experimental research project to preserve another aspect of the performing arts—the history of their rehearsals. We have specifically designed non-intrusive video recording and on-site documentation techniques to make this process transparent to the creative crew, and have developed a complete workflow to publish the recorded video data and their corresponding meta-data online as Open Data using state-of-the-art audio and video processing to maximize non-linear navigation and hypervideo linking. The resulting open archive is made publicly available to researchers and amateurs alike and offers a unique account of the inner workings of the worlds of theater and opera.

Abstract

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/.

Abstract

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.

Abstract

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.

Abstract

International audience; This ongoing work investigates usage-based document reengineering as a means to support authors in modifying their documents. 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.

Abstract

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.

Abstract

International audience; The ACAV project aims at improving videos accessibility on the Web to people with sensory disabilities. 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.

Abstract

8 p.; International audience; Our approach to address the question of online video accessibility for people with sensory disabilities is based on video annotations that are rendered as video enrichments during the playing of the video. We present an exploratory work that focuses on video accessibility for blind people with audio enrichments of videos composed of speech synthesis and earcons (audio notifications). Our main results are that earcons can be used together with speech synthesis to enhance understanding of videos; that earcons should be accompanied with explanations; and that a potential side effect of earcons is related to video rhythm perception.

Abstract

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.

Abstract

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.

Abstract

In this paper, we introduce the concept of “user policies”. The objective of policies is to specify user preferences in terms of presentation and interaction with information. Using this concept, the presentation/interaction with information will be adapted to user’s needs, making information more accessible. We define several kinds of policies (navigation, exploration, presentation, etc.). The concepts of “presentation policies” and “navigation policies” are studied in this article. As XML is the standard for encoding electronic information, we will apply the concept of policies to the browsing of XML Documents.

Abstract

International audience; It is a challenging task to identify eLearning courses parts that have to be revised to best suit learners' requirements. Reading being one of the most salient learning activities, one way of doing so is to study how learners consume courses. We intend to support course authors (e.g. teachers) during courses revision by providing them with reading indicators. We use the concept of reading session to denote a learner's active reading period, and we provide several associated reading indicators. In our server-side approach, reading sessions and indicators are calculated using web server logs. We evaluate the relevance of our proposals using logs from a major French eLearning platform. Results are promising: calculated reading sessions are theoretically more precise than other best applicable approaches, and course authors consider suggested indicators to be appropriate to courses revision. Using reading sessions and associated indicators could facilitate authors' work of course reengineering.
