The IDT4EU is an Erasmus+ funded project that will be developed between 2025-2028. It aims to modernise higher education by integrating Immersive Digital Twins (IDTs) into teaching, addressing digital skills gaps and enhancing industry-aligned learning. It equips educators with innovative tools, improves student engagement, and establishes a European framework for IDT adoption, supporting Erasmus+ priorities of innovative teaching and interconnected higher education systems.
