Within the framework of this project, the FeDiNAR system is being developed, which focuses on errors as a highly conducive learning opportunity and enables appropriate learning directly on the real machine.

Based on the didactic FeDiNAR concept, actions are recorded by means of digital twins of the learners and the real system, their consequences are simulated and visualised for the learners in AR. Cloud and web services enable learners and teachers in the FeDiNAR community to compile learning events and scenarios and evaluate them together.
