Project Overview

The Liberation AR is a location based Augmented Reality app we developed for the German broadcasting service Bayerischer Rundfunk and the Dachau Concentration Camp Memorial Site for the remembrance on the 75th anniversary of the liberation of the camp by the US army on the 29th April 1945. The Liberation AR can be downloaded on any mobile device and offers a self-guided tour through the Dachau memorial site that presents the Liberation day 75 years ago in a totally new immersive experience.

The Experience

On 29 April 1945, the Americans arrived at the Dachau concentration camp. At the time, 32,000 prisoners are on-site, half-starved, emaciated and sick. Hundreds die every day. Corpses pile up next to the overcrowded barracks…

In 5 stations, several eyewitnesses from the Liberation day tell their stories and how they experienced it.

The app starts with a map and an overview of all stations. Once the user comes near a station, the camera opens and let the user scan the physical marker that is installed on the memorial site. A digital path in AR then guides the visitor to the immersive Augmented Reality experience while the audioguide starts simultaneously. Additional information are displayed in a panel that can be swiped up and videos and historical photos are placed with centimetre accuracy at the spot where they once were taken.

If the user downloads the app and is not on the memorial site, the app then will forward to the project website.

The challenge to The Liberation AR mainly lays in the topic itself. The subject area of National Socialism and the Holocaust are very sensitive and emotional topics in German history. Not only for the memorial sites does this mean having a certain sensitivity for the conception of exhibitions and offers, but also for the development of the AR app experience when we had to take special care of. The requirement for The Liberation AR was thus that visitors engage with the liberation day at Dachau concentration camp in an immersive way, without crossing emotional boundaries and principles of memorial work.  

We at ZAUBAR achieved this in a close partnership and working together with our customers from this field. During this and other partnerships with memorial sites and museums, we could proof our experience and competences for it.
