Information filtering for mobile augmented reality

Abstract: Augmented reality is a potentially powerful paradigm for annotating the (real) environment with computer-generated material. These benefits will be even greater when augmented reality systems become mobile and wearable. However, to minimize the problem of clutter and to maximize the effectiveness of the display, algorithms must be developed to select only the most important information for the user. In this paper, we describe a region-based information filtering algorithm. The algorithm takes account of the state of the user (location and intent) and the state of individual objects about which information can be presented. It can dynamically respond to changes in the environment and the user's state. We also describe how simple temporal, distance and angle cues can be used to refine the transitions between different information sets.

Wearable 3D Graphics for Augmented Reality: A Case Study of Two Experimental Backpack Computers

Abstract: Graphical mobile augmented reality applications will only be effective if the wearable computers on which they run are capable of high-performance 3D graphics. However, no current commercial wearable system provides the graphical performance of even a typical modern desktop computer. In this paper, we describe two different experimental wearable graphics computers designed for prototyping augmented reality applications requiring fast 3D graphics. We explain the system requirements and design decisions that resulted in these architectures.
