UbitourAR: A ubiquitous tourism model based on augmented reality

Abstract

Abstract. 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 Gonçalves, 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.

Personalized Augmented Reality Based Tourism System: Big Data and User Demographic Contexts

“…For the prediction evaluation, the root mean square error, precision, recall, overall accuracy, and kappa indicators are provided. For the user study, a questionnaire [52] is used to evaluate the ease-of-use and the usefulness of the system.…”

“…After teaching the people how to work with the system, they were asked questions about using the system that were based on the map that was implemented and the system (Table 6). The questions were asked in two categories, which included the easiness and the usefulness of the system [52]. In order to perform this evaluation, the following form was prepared, and the tourists and the users of the system were asked to carefully complete this form.…”

Adição gradual da informação sobre um patrimônio arquitetônico: produção de modelos e de sentidos

“…Estas possibilidades remetem ao conceito de turismo ubíquo. ConformeSilva et al (2014), este conceito é empregado por guias eletrônicos de turismo, quando possibilitam através de georreferenciamento e de dispositivos móveis, como tablets e smartphones, fornecer informações contextuais, de maneira interativa e instantânea, do local para o usuário. Certamente, muitos dos roteiros turísticos realizados na Praça Coronel Pedro Osório devem estar sendo dirigidos sob a consulta, pelo próprio turista, de sites especializados, incluindo aquele organizado pela Prefeitura Municipal de Pelotas.…”
