Wearable augmented reality system using invisible visual markers and an IR camera

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.
