The Minister for Culture and Science of North Rhine-Westphalia, Ina Brandes, visited the 'Lab-on-Tour' science truck at the Hamm-Lippstadt University of Applied Sciences (HSHL) campus on April 16, 2025. The 'Lab-on-Tour' is part of the 'Digitalise_SWF' project started in 2023, funded by the Federal-State Initiative 'Innovative University'. Minister Brandes gained insights into the activities of the transfer project and experienced virtual reality and driving simulations in the truck.

Brandes emphasized the importance of nurturing young talents in MINT subjects and the role of the science truck in engaging students in mathematics, informatics, natural sciences, and technology. The project aims to strengthen digitalization skills in the region and benefit small and medium-sized enterprises.

During the visit, the focus was on virtual and augmented reality in product development and connected mobility, showcasing a virtual industrial environment and a driving simulator.
