This paper describes a wearable augmented reality (AR) system using invisible visual markers. Some AR systems use visual markers in order to measure the position and orientation of user's viewpoint. However, conventional visual markers usually impair the scenery. This paper proposes a system using invisible visual markers consisting of translucent retro-reflectors. The system can be realized without undesirable visual effects and power supply for infrastructures.
