Résumé
When working with mobile Augmented Reality (AR), users often need to visualize off-screen points of interest (POIs). These POIs belong to the context since they are not directly observable in the 3D first-person view on screen. The aim is to present the 3D direction and distance of each POI in a 3D first-person view. The context in mobile AR can include a large number of POIs including locally dense clusters as in mobile AR systems 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 mobile AR adaptation of a 2D visualization technique. Halo3D displays the 3D direction and distance of off-screen POIs in a high POI-density environment. The paper describes the design elements of Halo3D and outlines the experimental study to be conducted. The first experimental results indicate that users prefer visual attributes that minimize the visual intrusion on screen.
