Abstract
When working with mobile Augmented Reality (AR) applications, users need to be aware of relevant points of interest (POIs) that are located off-screen. These POIs belong to the context since they are not observable in the 3D first-person AR view on screen. The context in mobile AR can include a large number of POIs including locally dense clusters as in mobile AR applications for production plant machine maintenance. Existing solutions display 3D arrows or an area on the edges of the screen to represent the POIs of the context. These techniques display the direction but not the distance of each POI. We present Halo3D, a visualization technique that conveys the 3D direction and distance of off-screen POIs while avoiding overlap and clutter in a high-POI-density AR environment.
