With the KDH augmented reality app you can retrieve digital additional information such as video and 3D animations in addition to the printed publications of the ZdH (German Confederation of Skilled Crafts) and the KDH (Competence Centre for Digital Craft) as well as the Chambers of Crafts. The app recognises the pages and images in the brochures provided they are enriched with digital additional information. A written note or a corresponding symbol is generally found on the digitally enhanced print products
