From an early age, we learn to assign functions to physical objects, to pick them up, and test them out. Interfaces that build on this aspect have advantages over classic screen-based interfaces - they reduce mental load during use and promote collaboration and creative thinking. This work takes advantage of this aspect.

"Tactipe" is an installation that can be used for designing physically. Several users can influence the headline of a typography poster together by using "Tangibles" and thus intuitively and playfully get involved in the design process. The tangibles consist of sensors and 3D-printed covers that can be moved or changed in various ways. The headline of the poster can be changed in colour and font, can be tilted and bent in 3D space, the text can be stretched, compressed and the letters can be rotated. It is also possible to enter the headline text using speech recognition. This encourages creative collaboration, which is possible even without prior knowledge of design software.
