Founded in 1668, Merck is the oldest pharmaceutical/chemical company in the world and a leading company in the area of science and technology. In the summer of 2015 the headquarters of Merck in Darmstadt was equipped with an interactive routing system for the outdoor area. This Guide3D application guides visitors to 30 destinations by showing the way in a 3D animation from bird’s view. The outdoor application also allows its user to download the way via QR code onto the smartphone to view the routing again. An installation of the app is hereby not necessary. The service is available to the visitors in 12 languages, including German, English or Spanish.
