New interaction paradigms such as Ubiquitous Computing or Augmented Reality are emerging. We believe that it is evident that the change of paradigm has to suppose a change in the design methodology of these future interactive systems. The purpose of this paper is to present our proposal about how this change has to be done in a real Use-Case. We offer the use of Augmented Reality during a visit to the Vilars archaeological site, in Arbeca (Lleida - Spain), as an example. The document is focused on the design of the system, explaining how to migrate from the Desktop paradigm to the Augmented Reality one adding the location attribute in order to organize a visit to the site, enabling the establishment of a relationship with the interaction by direct manipulation. This relation establishes a different kind of visit to those carried out at present, based on guides, books or web sites, among others. We present how the functionality and the user dialog has to be done for the accomplishment of a site visit in Augmented Reality using the User-Centred Process Model. 1 Introduction During a visit to an archaeological site the visitor obtains the information of the diverse elements from the site by means of informative fixed panels -arranged at the key points of the tour-, leaflets, books, devices audio (individual) and expert guides. In the case of the panels, the visitor follows the site searching for the ones which show the characteristics of the point where he/she is located. Fig. 1. Informative panel of the fortress and a “small” map of the actual site. These visits do not differentiate between types of users and as a consequence they limit the visitor who is looking for additional information.
