Within the EDGE-Skills project, the Conservatoire national des arts et métiers (Le Cnam) is leading the project ‘Video4XR’, which is focused on improving the way in which trainers and educators evaluate learners’ performance in immersive learning practical sessions.
As virtual reality (VR) training becomes more widespread in educational and professional contexts, the demand for effective feedback on VR sessions has grown significantly. Trainers often struggle to know exactly what learners did during a session, making it difficult to provide meaningful feedback or guidance on how to improve. The Video4XR use case addresses this issue by developing a solution that enables trainers to access detailed reports and visual records of learners’ actions within the virtual environment.
The core problem that Video4XR addresses is the lack of visibility into VR sessions once they have been completed. Currently, trainers who use VR as a teaching tool have no direct way to observe learners’ behaviour or evaluate their performance after a session. Video4XR resolves this issue by generating comprehensive session reports to help trainers analyse what occurred in VR. This new level of insight enables trainers to discuss specific actions with trainees, highlight mistakes and reinforce learning through reflection. Ultimately, by improving the quality of post-session feedback, the solution enhances the efficiency and educational value of VR-based training.
Video4XR captures video recordings and learning traces from each VR training session. These materials are automatically sent to Ubicast, where they are processed into structured, chaptered videos that highlight key events and moments of interest. The enriched videos are then returned to the trainer, who can review, discuss and use them as a basis for evaluation and further training with the learner. The system integrates seamlessly into existing learning management systems. Trainers can easily add a Moodle module to any VR session, while an educational feedback module automatically processes and organises the data without requiring any manual configuration.
The innovation of Video4XR lies in its ability to combine VR activity tracing with video analysis and educational feedback, creating a smooth and intelligent bridge between immersive training and reflective learning. It turns a traditionally isolated experience into a collaborative and data-driven learning process.
This approach offers several key benefits. Trainers can integrate VR tools directly into Moodle with minimal effort, receive chaptered feedback videos enriched with session statistics and engage in structured discussions with learners based on real performance data. The solution supports evidence-based teaching, helping to make every VR session more effective and pedagogically meaningful.
The Video4XR project has been developed in collaboration with two partners: Mimbus and Ubicast. Mimbus is responsible for creating the technical solution, capturing session data, sending videos and traces, and providing Moodle integration modules. Ubicast manages the processing and transformation of the video and data to create one module integrating the chaptered educational videos and a chat system. This module is returned to trainers for feedback and analysis.
The project is now in its final development phase. The next steps involve finalising the product and collaborating closely with Le Cnam trainers who are already using VR tools in their courses, in order to integrate Video4XR into their teaching. These trainers will participate in the testing phase and provide feedback to refine the solution.
Through Video4XR, CNAM and its partners intend to enhance the transparency, interactivity, and effectiveness of VR training, thereby bridging the gap between immersive experiences and measurable learning outcomes. Educators, training providers and digital learning specialists are invited to contribute to this initiative and help shape the future of educational feedback in virtual reality.
