Augmented Reality in Outdoor Settings: Evaluation of a Hybrid Image Recognition Technique

AbstractNew technologies such as Augmented Reality (AR) have already been exploited in the promotion of unique and well-known cultural assets. Nevertheless, different types of heritage assets can be found scattered in many different places, in both urban and rural landscapes, where AR applications may not function properly due to problems concerning the effectiveness of GPS or image recognition methods. It is an important issue that limits the exploitation of AR technology with a view to hidden cultural heritage promotion. The current study presents a hybrid image recognition technique used in an AR application and its evaluation in the outdoor settings. The hybrid technique is based on an image-based marker and its evaluation mainly aimed to study if and to what extent it is accepted by the users, if it raises aesthetic issues, and if it affects the use and acceptance of the AR in culture field. The evaluation was based on a qualitative research and the results showed that to most participants the used hybrid technique does not create an aesthetical issue. Additionally, all participants found the AR app useful and easy to use and they consider that the AR technology can significantly contribute to the promotion of cultural heritage.
