With the Erleb-AR app you can explore the roman settlements of Aventicum and Augusta Raurica and marvel at the Christoffel tower at its original site. Much of the rich Swiss cultural heritage is only partially available today, in the form of ruins or archaeological findings, or it has completely disappeared. New emerging technologies make it possible to merge camera images with models of historical buildings, objects and people. With reality enriched in this way ("Augmented Reality - AR") one no longer has to rely solely on their own imagination, but one is transported back to the past at the scene of the event. The Erleb-AR app was developed at the Institute for Human Centered Engineering HuCE at the laboratory for computer perception and virtual reality (cpvrLab) of the Bern University of Applied Sciences with generous financial support from the Federal Office of Culture FOC.
