Augmented paper maps: Design of POI markers and effects on group navigation

One popular and wide use of augmented-reality based application, is the projection of points of interests on top of the phones’ camera view. In this paper we discuss the implementation of an AR application that acts as a magic lens over printed maps, overlaying POIs and routes. This method expands the information space available to members of groups during navigation, partially mitigating the issue of several group members trying to share a small screen device. We examine two aspects critical to the use of augmented paper maps: (a) Appropriate visualization of POIs to facilitate selection and (b) augmentation of paper maps with route instructions for use in group situations. In this paper, we evaluate POI visualization in a lab setting and augmented paper map navigation with groups of real tourists in a preliminary field trial. Our work complements existing literature introducing self-reporting questionnaires to measure affective state and user experience during navigation.
