Shared annotation database for networked wearable augmented reality system

This paper describes a database of annotation information for augmented reality (AR) on wearable computers. With the advance of computers, AR systems using wearable computers have received a great deal of attention. To overlay annotations on the real scene image, a user's computer needs to hold annotation information. The purpose of this paper is to construct a networked database system of annotation information for wearable AR systems. The proposed system provides users with annotation information from a server via a wireless network so that the wearable computers do not need to hold it in advance and information providers can easily update and add the database with a web browser. In experiments, the user's position-based annotations have been proven to be shown to the user effectively. © Springer-Verlag 2004.
