Visible Portion Estimation of Moving Target Objects for Networked Wearable Augmented Reality

Abstract

This paper describes a new visible portion estimation method of moving target object for networked wearable augmented reality (AR) system. In annotation overlay applications using AR systems, it is important to improve readability and intelligibility of annotations in a user's view. View management makes it possible to appropriately generate annotation overlay images for users so as to intuitively understand annotations. For instance, overlappings of annotations and other objects can be prevented by using a view management technique. View management requires visible portions of 3D target objects in a 2D view plane. This paper proposes a visible portion estimation method for moving target objects based on positions and shapes of the moving target objects. The wearable augmented reality system obtains positions of target objects via wireless network for estimating visible portions of target objects in the user's view. Annotations are able to be overlaid by using view management techniques with our proposed visible portion estimation.
