Several tools that enable users to collaborate simultaneously in a digital environment have been developed. At the end of the 1990s, the Teal project at the Massachusetts Institute of Technology developed a digital tool usable via computers to simulate and visualize Physics concepts for first-year students, for example by illustrating complex electromagnetic phenomena. It was used in a classroom, with tables arranged as islands for the occasion to encourage collaboration . In 2012, McArdle and Bertolotto presented a VR e-learning system that creates a collaborative virtual environment usable remotely to stimulate learners during their learning . The ease of use of the tool, together with its collaboration and socialization features, increases user's engagement and motivation, thereby reducing the drop-out rate .
