In the pursuit of modern and future-thinking education, students must be more oriented towards research and the practice-oriented development of products and processes. Experts from various disciplines are currently forced to use complex measurement and equipment infrastructure but are unable to adequately combine and visualize the increasingly complex results from the various fields in a suitable form. To explain these complex phenomena to students as intuitively as possible, the augmented reality app ARCTIC (“Augmented Reality Comes To Interactive Campus”) was designed for practice-oriented lectures. This approach enables the projection of (simulation) data into physical spaces using smartphones and facilitates user interaction with 3D models. By using open-source principles, the app promotes collaboration and enables experts from different fields to provide cost-effective solutions for teaching individually. This approach not only improves the accessibility of the app but also promotes a community-oriented, sustainable development model. The app was tested under pedagogical supervision in real conditions with students from various disciplines of chemical and process engineering, as well as AEC companies. The evaluation showed that students and company representatives are extremely open to the developed AR solution. They would strongly support the further integration of the app into teaching. This was also evident from the surveys, in which students participated constructively and contributed further ideas. Augmented reality is a promising technology with the potential to revolutionize teaching. ARCTIC is a successful example of how AR can be integrated into the classroom to explain complex phenomena intuitively and interactively to students.
