Annotating user-viewed objects for wearable AR systems

By realizing augmented reality on wearable computers, it is possible to overlay annotations on the real world based on the user´s current position and orientation. However, it is difficult for the user to understand links between annotations and real objects intuitively when the scene is complicated or many annotations are overlaid at the same time. This paper describes a view management method which emphasizes user-viewed real objects and their annotations using 3D models of the real scene. The proposed method highlights the objects viewed by the user. In addition, when the viewed object is occluded by other real objects, the object is complemented by using an image, which is made from 3D models, on the overlaid image.
