A wearable augmented reality (AR) system has received a great deal of attention as a new method for displaying location-based information in the real world. In wearable AR, it is required to precisely measure position and orientation of a user for merging the real and virtual worlds. This paper proposes a user localization system for wearable AR in indoor environments. To realize a localization system, it is necessary to easily construct environments for localization without producing undesirable visual effects. In the proposed system, wallpapers containing printed invisible markers are pasted on ceilings or walls. To construct environments for localization, this system contains a tool which calibrates the alignment of the markers from photos of the markers with digital still camera. The user's position and orientation are estimated by recognizing the markers using an infrared camera with infrared LEDs.
