We present a serious game designed to help players/learners develop socio-moral reasoning (SMR) maturity. It is based on an existing computerized task that was converted into a game to improve the motivation of learners. The learner model is computed using a hybrid deep learning architecture, and adaptation rules are provided by both human experts and machine learning techniques. We conducted some experiments with two versions of the game (the initial version and the adaptive version with AI-Based learner modeling). The results show that the adaptive version provides significant better results in terms of learning gain.

Abstract This paper presents our work to generalize the ExploraGraph system, in order to offer generic adaptive support among different e-learning applications. We define XMLSchema models of applications, learner, tasks and domain models. A generic rule editor is then used to describe contextual help to activities of learners or other actors in the context of e-learning. Thus the rule editor makes it possible to describe axioms and boolean reasoning linking task, user models and interaction events, in general terms and for ...

This article is an attempt to promote R&D methodology that is action- oriented in order to improve the development of tele-learning environments and software artefacts fully adapted to learning activities. First we start by presenting an overview of the two main phases of action-oriented research, stressing the importance of control methods. Secondly, we describe difficulties in applying these methods and, finally, we introduce the LORIT, a recent initiative intended to support instrumentation in tele-learning research.

La définition et la mise en œuvre d'un système formel de support à la collaboration dans un environnement d'apprentissage conduit à préciser au préalable le processus de collaboration lui-même et les mécanismes qui lui sont sousjacents. Le texte présente la notion d'engagement qui apparaît essentielle à la poursuite et à l'efficacité de la collaboration et montre comment celui-ci doit reposer sur une connaissance du partenaire, de la tâche, des échéances et des coûts/ bénéfices associés. En s'inspirant d'un modèle motivationnel de l'apprentissage et de la recherche d'identité des participants, il pose un regard critique sur ce qui existe pour soutenir l'engagement et suggère un certain nombre de pistes pour améliorer la connaissance de soi à travers la manipulation de son modèle d'apprenant, la visibilité contextuelle des partenaires et du processus, et le contrôle et la rétroaction au sein de l'interaction.

Mots-clés : apprentissage à distance, collaboration, interfaces, engagement. Abstract : In order to define a system to formally support collaboration in an environment for learning, it is necessary to define the forces underlying collabo- ration. This paper presents how collaboration relies on knowledge about the partners, the task, the deadlines and the cost/benefits of the exchange. Inspired by a motivational model of learning and the need for recognition, it examines how engagement can be fostered by a better control and visibility of each participant's learner model and his contribution to the collaborative process.

Standing at the conceptual intersection between various fields (i.e., Communication, Human-Computer Interaction, Consumer Behavior, Social Psychology, and Usability), this research investigates the influence of social functionalities on consumers' online attitude toward contributing content to the website. Relying on social psychology theories such as group influence and similarity-attraction, one of our central predictions is that when online consumers are exposed to Web sites containing features supporting the site sociability, their attitude toward contribution will be greater than when not exposed. Furthermore, galvanic skin response was used to assess emotional response during the task, to complement more traditional data collection methods. Our results show that online consumers’ attitude toward contribution is positively influenced by social functionalities, and that emotional reactions mediate this influence.

Predicting the psychological state of the user using physiological measures is one of the main objectives of physiological computing. While numerous works have addressed this task with great success, a large number of challenges remain to be solved in order to develop recognition approaches that can precisely and reliably feed human-computer interaction systems. This paper focuses on one of these challenges which is the temporal asynchrony between different physiological signals within one recognition model. The paper proposes a flexible and suitable method for feature extraction based on empirical optimisation of windows’ latency and duration. The approach is described within the theoretical framework of the psychophysiological inference and its common implementation using machine learning. The method has been experimentally validated (46 subjects) and results are presented. Empirically optimised values for the extraction windows are provided.

In order to improve human-computer interaction, eye-tracking measures and physiological reactions are combined to the context of navigation and the structure of actions to analyze emotional state of users. Understanding affective reactions is essential to improve the human-computer interaction and the design of systems. In the domain of e-commerce those techniques are being used informally to observe interactions during the

ABSTRACT The emphasis on user experience has lead researchers in HCI to take into account emotions in the evaluation of interactive systems. New evaluation approaches are required to integrate this aspect. Standard qualitative approaches are limited as they are based on observations and interviews after the interaction, therefore limiting the precision of diagnosis. User experience and emotional reactions being by nature dynamic and contextualized, evaluation approaches should be as well in order to diagnose interaction more accurately. This paper presents a quantitative and dynamic evaluation approach allowing contextualization of users' emotional reactions. The approach relies on eye tracking, physiological measures and task recognition and was implemented in an evaluation tool. The proposed tool was experimentally validated using two types of interactive systems: training simulator (31 participants) and e-commerce site (11 participants).
