Abstract. This article comprises a study on user experience when interacting with different modes of mobile interfaces. Our emphasis is on application instances commonly found in mobile app stores, which utilize sensor-based augmented reality or two-dimensional zoomable maps to visualize points of interest (POIs) in the vicinity of the user. As a case study, we developed two variants of an Android application addressed to public transportation users. The application displays nearby transit stops along with timetable information of transit services passing-by those stops. We report findings drawn from an empirical field study in real outdoors conditions. The evaluation findings have been cross-checked with logged (usage) data. We aim at eliciting knowledge about user requirements related to mobile application interfaces in this context and evaluating user experience from pragmatic and affective viewpoints.

1 Introduction Recent developments in mobile computing (such as the wide penetration of mobile devices equipped with camera, GPS receiver and inertial sensors) shaped a favorable technology landscape for mobile augmented reality (MAR) applications. MAR services provide a novel interface to the ubiquitous digital information in the physical world, hence serving in great variety of contexts such as tourism, cultural heritage, games, advertising, etc. [1]. The ongoing rise of AR is evidenced from the large body of

publications describing MAR demonstrators [1], the multitude of MAR apps in the mobile application markets, as well as the proliferation of publicly available MAR frameworks, such as Wikitude1, Android Augmented Reality Framework2, etc. A considerable share of MAR applications are location (sensor)-based. The majority among them inherently provide means for superimposing virtual objects on the physical environment framed by the device’s camera; for instance, floating markers placed upon nearby points of interest (POIs). Such MAR interfaces become more and more prevalent, commonly substituting conventional map visualizations. The research questions addressed in this article are: (a) whether the MAR paradigm indeed involves a more natural and intuitive interface than that of conventional two-dimensional maps; (b) what is the actual quality of exper
