INSIDE-CoVE aims to develop a comprehensive vocational training framework for the construction sector, integrating innovative technologies like Virtual Reality (VR), Augmented Reality (AR), and Mixed Reality (MR) to provide immersive, hands-on learning experiences. The project focuses on digitalization, sustainability, and skills development, aligning with key European policies like the European Green Deal, the European Skills Agenda, and the Osnabrück Declaration. It supports the twin transition to a digital and green economy by incorporating BIM for seamless collaboration across the construction lifecycle and promoting inclusive, flexible learning for both blue- and white-collar workers.
