Els Vilars is an archaeological site inhabited during First Iron Age and Iberian Period (from 750 to 325 BC) and it is placed in the northeast of Iberian Peninsula. As a monumental site, it has been declared Bé Cultural d’Interés Nacional (legally, the highest monumental category of Spanish State) and it is supported by a Development Plan, which its finality is to put the site in value and arrange it to the visitors.
In this sense, the presentation of the site has to take into account the new technologies. That is the reason why the Grup d’Investigació Prehistòrica (GIP) and the Grup de Recerca Interacció Persona-Ordinador (GRIHO), both come from University of Lleida (UdL), work together on the elaboration of VILARS AR PROJECT. This project pretends to create an augmented reality (AR) system applied to the site visit, where the visitors will be able to observe virtual reconstructions from different visitable points with a portable visualization device (a tablet pc) and also to interact with other offered multimedia contents (image, text and audio). All this contents characterize, put in context and “augment “ the visible reality. Our main motivation is to generate an information mechanism for the visitors which can responds to the most possible questions, covering any user curiosity. At the same time, the device has to offer the visitors the possibility of deciding what they want or what they do not want to know. In this sense, the users plurality has been also taken into account, so that the device has to be adapted to the users according to their knowledge, capabilities and interests. At present the project is in its first execution phase. We have established the visitors itinerary, the different points of interest, the subjects to develop, the different kinds of potential public and the usability aspects. A first prototype has been created with contents oriented to two different types of public and prepared in two languages. Nowadays, this prototype is in course of evaluation with real public.
