Short description of important scientific result: Creation of mathematical and software for an automated system for designing and reproducing interactive multi-user simulators with immersion in virtual immersive environments. Approaches are proposed for interpreting the behavior of a user in a virtual environment when evaluating the bio-signals of a person immersed in an immersive virtual learning environment; the degree of immersiveness of the virtual learning environment for specific users; involvement in the learning process of a user located in an immersive virtual environment.
