Dynamic Labeling Management in Virtual and Augmented Environments

摘要

Most applications in virtual and augmented reality usually need to visualize large amounts of extra text/image/video annotations associated with objects to assist user's navigation. Labeling is one of the most intuitive techniques to achieve this goal, which attaches specific texts to related objects to provide users a clear environmental clue. The basic problem of labeling is the clutters due to unexpected overlapping and occlusion among labels and objects, which makes the environment ambiguous and obscure. In this paper, we present the interactive system of dynamic labeling management to address this problem for virtual environment navigation applications. Our system integrates the techniques of labeling with adaptive placement, view-driven label filtering and structured label searching. These features have been developed in our system with well display of augmented labels in VR applications.
