This paper describes a database of annotation information for augmented reality ( A R ) o n w earable computers. With the advance of computers, AR systems using wearable computers have received a great deal of attention as a new method for displaying location-based information in real-time. To overlay annotations on the real scene image, a user's computer needs to hold annotation information. Up to this time, since a database of annotation information is usually held in advance in the wearable

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 this study, we h a ve developed a shared database of annotation information and have proven the feasibility of the prototype system with preliminary experiments. In experiments, the orientation and the position of user's viewpoint are measured by i n tegrating several kinds of sensors. The user's position-based annotations have beenproven to be shown to the user automatically. Moreover, we have conrmed that the database can be successfully updated and added by information providers with a web browser.
