Embedded Virtual Views for Augmented Reality Navigation

Figure 1: An embedded virtual view allows users to follow a guided route, without leaving the egocentric viewpoint. (a) The navigation aid turns around the corner and the user’s view is blocked by the building. (b) By extending the egocentric viewpoint with an additional embedded virtual view, the user is still able to perceive the route indicated by the navigation aid. Note that the additional view embeds the navigation aid correctly in the environment. In this paper, we present virtual embedded views used for turnbased pedestrian navigation in Augmented Reality (AR). Embedded views allow users to see around occluding structures and at the same time seamlessly integrate the augmented navigation aid into the otherwise occluded view. Users get a preview on upcoming route changes, without the need to consult an additional map view. We compare embedded views to other methods revealing the occluded navigation aids. We demonstrate that the technique is more screen-space efficient when compared to a typical x-ray vision technique, and may better facilitate the mental linking of information, when compared to a mirror.
