UbitourAR: A ubiquitous tourism model based on augmented reality

Nowadays, Brazil has an expected growth in the tourism sector due to the FIFA World Cup (which had a huge success) and the Olympics in Rio de Janeiro. However, there is a lack of tourism applications for Brazil, such as Electronic Tourism Guides (ETGs) for mobile devices. The existence of ETGs that takes into account real world environment is still very rare. By taking into account this scenario, this article presents a ubiquitous tourism model based on augmented reality. The proposed architecture, which is called UbitourAR, takes into account the context awareness focusing on localization-based services allied with user profile and restrictions. This article describes the development of UbitourAR enabling users to interact with the real world environment using augmented reality when visiting a place or point of interest (POI). In order to evaluate the model we had taken two approaches. Firstly, we evaluated the ontology proposed using scenarios. Secondly, we evaluated the usability in terms of efficiency, effectiveness and user satisfaction. For doing that, we developed a mobile application for the Caminhos de Pedra itinerary, in Bento Goncalves, Brazil. The proposed model extends the previous work of Ubitour by adding augmented reality. The results of the tests showed a user acceptance higher than 80%, which encourages the research in augmented reality allied with ubiquitous tourism.
