For the Märkisches Museum Berlin, in collaboration with Humboldt Forum, I designed an interactive prototype to enhance the wooden city model of Berlin in 1750. Targeted at diverse visitor groups, the concept combines 3D conductive elements and digital projections, triggered by touch and powered by Arduino and TouchDesigner, to bring historical events and contexts to life. This approach transforms the static city model into an engaging, memorable experience, inviting exploration and deepening understanding of Berlin’s rich history. This project was part of a course at the FH Potsdam.
