We would like to enable our users to discover historical pictures of Zürich and go to the places where they were taken. They can take the perspective of the photographer from around 100 years ago and see how the places have changed. They can also share their photographs with the community. We have planned two thematic tours, one with historical photographs of Adolphe Braun and one with photographs connected to the subject of silk fabrication. The tour is enhanced with some historical information. In the collections of the ETH, Baugeschichtliches Archiv, and Zentralbibliothek Zurich, Graphische Sammlung, we found pictures to match the topics above and to set up a nice tour for the users. In a second step we went to the actual spots to verify if the pictures could be taken and to find out the exact geodata. Meanwhile, our programmers inserted the photographer's stops on a map. As soon as the users reach the proximity of the spot, their phone will start vibrating. At this point, the historical photo will show up and the task is to search for the right angle from where the historical photograph has been taken. At this point, the users are asked to take their own picture. The app allows the users to overlay the historical with the current picture so a comparison can be made. The user is provided by additional information like the name of the photographer of the historical picture, links to the collection the picture comes from, the building itself, connection to the silk industry etc. Here is the link to our prototype: https://glamhistorytour.github.io/HistoryTourApp/
