- Abstract
- There are growing understanding and interest of AR(Augmented Reality) technologies with development andpopularization 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 interactwith the images or real world space. Advanced outdoor AR games require interactions with the user's geographiclocation and camera-captured images. Therefore, for interaction with various contents, outdoor AR games needinformation on the user’s location and the surrounding environment. However, GPS estimates contain largeerrors (sometimes larger than 50 meters) in urban environments because high buildings block or reflect GPSsignals: geometric layout of GPS satellites is restricted. Uncertainty range provided by GPS receivers are alsoimpractical 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. Were-calculated the location error boundary using the satellite information obtained by the GPS receiver. Calculatederror boundary was used to find the location-based information. This study is beneficial for reducing practicaluser’s location range in urban environment for outdoor AR games.
