ARQuatern is an application created for the Quaternari research group and only functional for the Castelldefels library. In this application we can see augmented reality experiences of rhinoceros and deer recreations found in the "Cova del rinoceront" in Castelldefels.This work has been carried out within the framework of the Strategic Transfer Plan of the Open University of Catalonia (UOC), co-financed by the Secretary of Universities and Research of the Generalitat de Catalunya through FEDER Funds.
