In the wake of the COVID-19 health crisis, governments around the world made educational continuity during school and university closure a priority. Many countries adopted online education as an alternative to face-to-face courses. This situation has led to an awareness of the importance of analyzing learning traces and data left by students to mea...

Intelligent learning systems provide relevant learning materials to students based on their individual pedagogical needs and preferences. However, providing personalized learning objects based on learners’ preferences, such as learning styles which are particularly important for the recommendation of learning objects, re-mains a challenge. Recommen...

An adaptive learning system aims to provide learning that is adapted to a learner’s current status, different from the traditional classroom experience. A key element of an adaptive learning system is the recommendation system, which provides the most suitable resources based on learner profiles. Recommending the most appropriate learning resources...

Online learning is an alternative to the traditional (face-to-face) educational system. Contrary to traditional teaching (classroom), distance learning is characterized by the lack of physical contact between instructors and students and also between students within a classroom. Unfortunately, some learners may fail or even stop learning online qui...

Pre-evaluation of the learner's level is a common learning strategy designed to determine the prior knowledge and skills of learners. A pre-evaluation is carried out at the beginning of the course and based on the results obtained, personalized resources will be provided that respond to individual learner needs.

Nowadays, the user experience (UX) has become an essential concept of human-computer interaction (HCI) and occupies an increasingly important place in companies interested in this field. Designing a system or product with a good user experience is one of the main objectives of any digital project. E-learning systems must adapt because, beyond the b...

Personalized e-learning has often been linked to recommender systems, because to be able to personalize a teaching process it is essential to consider the specificities of each learner. The use of recommender systems has thus developed in education, and a lot of research work is beginning to take an interest in it, taking advantage of the automatis...

Online learning environments (OLE) have provided learners with personalized content through the use of Recommendation Systems (RS). Some RS are based on a learner’s profile to offer content that matches his/her preferences, others consider the learner in a collective setting and offer him appreciated or popular content in his/her group.

The flexibility, availability and functionality of online learning environments (OLEs) open up new possibilities for classroom teaching. However, although these environments are becoming increasingly popular, many users stop learning online after their initial experience. This paper aims to develop a new multi-dimensional research model allowing to...

Mobile terminals have become an integral part of our experience; we rely on these devices in almost all our daily actions. But although these terminals offer innovative opportunities, especially in terms of teaching practices, their adoption within universities still presents a great challenge.

The goal of HCI researchers is to make interaction with com- puter interfaces simpler, efficient and more natural. In a context of object manipulation, we think that reaching this goal requires the ability to pre- dict and recognize how humans grasp then manipulate objects. This is based on studies explaining human vision, reach, grasp taxonomies a...

Besides the emergence of many input devices and sensors, they are still unable to provide good and simple recognition of human postures and gestures. The recognition using simple algorithms implemented on top of these devices (like the Kinect) enlarges use cases for these gestures and postures to newer domains and systems. Our meth- ods cuts the ne...

This paper presents a new type of gesture for identifying spatio-temporal patterns: the analog gesture. Analog gestures can be characterized by some features (speed, acceleration, direction, and angle) which describe the dynamic morphology of the gesture. At first, we detail interactive tasks that should benefit for the use of analog gestures. Then...
