The authors conducted a study aiming at applying Augmented Reality technology in the field of architecture. There are some problems in the method of marker tracking when it is applied in the field of architecture. The authors groped the solutions which don't depend only on the method of marker tracking. The solution for indoor uses a 3-axis orientation sensor and marker tracking. The solution for outdoor uses a 3-axis orientation sensor and RTK-GPS. In this paper, how the system was implemented and evaluated is described in detail.
