The app recognizes images, sketches or QR codes on site and displays the appropriate digital content, full screen or directly embedded in reality, including 3D objects and holograms. At the start there is the first project "Rolf's Winter Secrets" by Rolf Zuckowski and Sarah Settgast, a digital extension to the book of the Deutsche Pappebuch Gesellschaft (soon also with its own app in the store).
