영문 초록

There are growing understanding and interest of AR(Augmented Reality) technologies with development and popularization of smart phones. Most AR shooting games use the sensor information of the smart phones only. Although images captured by a camera are used as backgrounds in these games, game contents do not interact with the images or real world space. Advanced outdoor AR games require interactions with the user's geographic location and camera-captured images. Therefore, for interaction with various contents, outdoor AR games need information on the user’s location and the surrounding environment. However, GPS estimates contain large errors (sometimes larger than 50 meters) in urban environments because high buildings block or reflect GPS signals: geometric layout of GPS satellites is restricted. Uncertainty range provided by GPS receivers are also impractical because they do not consider these reflections and the geometric layout of GPS satellites. In this paper, we developed a system that provides practical user’s location range in urban environments. We re-calculated the location error boundary using the satellite information obtained by the GPS receiver. Calculated error boundary was used to find the location-based information. This study is beneficial for reducing practical user’s location range in urban environment for outdoor AR games.
