Together with our digital partner, the MIREVI Lab at the University of Applied Sciences Düsseldorf, we research participation, communication and perception of art using innovative technologies. We develop prototypes, test them in museums and make them available open source. In the first project, we asked ourselves how object texts in the exhibition can be designed in a participatory way on a digital basis. The result is the augmented reality app ARt chat. Currently we are working on the topic WebXR.
