Impact de la réalité virtuelle sur la formation à distance

Abstract : The various possibilities offered by virtual reality have made it possible to explore different uses in several scientific fields. In the field of learning, various studies have shown that this technology has a positive impact on education. It offers a powerful flexibilityin the possibilities of presenting information to the learner and introduces sensorimotor and cognitive activities in the learning process. Training in virtual reality environments has many advantages over training in real environments. In addition, several research studies have shown that this technology has a positive influence on the user experience of learners. Although the contribution of virtual reality is proven in the field of learning in general, the distance learning sector remains little explored by research. The first research studies have shown the usefulness of this technology, particularly for collaborative learning situations involving participants in the learning process, and promoting learner-learner and learner-teacher interactions. However,there is still very little information available to evaluate the usability and acceptability (or user experience) of this technology in a distance learning context. Furthermore, the design of virtual reality environments is considered a complex task, as it is difficult to anticipate the behavior and the way users will perceive, understand and use the artifact. The risk that a designed environment will not meet the expected requirements is then high. Moreover, the distance between participants, which is one of the major causes of dropout in distance learning courses, is little or not addressed in existing design approaches. In this thesis, we first propose to formalize a design approach for virtual reality environments specific to distance learning. Our approach is based on the general model of virtual reality and the human operator-centered design, and focuses on the specificities of distance. Then we propose the specification of a collaborative virtual reality environment for distance learning based on a research-oriented design approach. Finally, following an experimentation with several participants in a collaborative virtual reality environment, we show how virtual reality positively impacts the feeling of co-presence between learners in a distance learning context.
