Abstract-This paper presents an approach to designing the user experience for interactive systems in open scenarios that involve augmented reality and mobile devices. We discuss the methodology we have used, which is a variation of contextual design, and resulting prototypes for a platform that will provide functionality for users to interact with augmented reality features in cultural and historical places, which are referred to as points of interest. Also, we report on preliminary results of the evaluation of our prototypes with potential users.Index Terms-Augmented reality, contextual design, gamification, point of interest, user experience.
