Time Traveller offers a virtual journey in time. Via cross-fading historical photos, movies or computer generated images, users can travel back and forth in time. This Augmented Reality Device can be positioned to explore exhibits in a museum or touristic sites. In front of the Brandenburg Gate for example, the Berlin Wall becomes visible, once the viewer travels back into the past. Time Traveller is a co-development of ART+COM AG and büro+staubach.
