Big Fat Wand (BFW) is a portable laser projection equipment to develop augmented reality (AR) system for an open collaborative space. A marker type AR system is a kind of AR systems, which uses some symbol markers to show the location of the annotation information on a tafget object. This paper proposes a new method to handle projection markers with BFW. The features are that BFW directly projects markers on a target object, and that they are able to be used in any places even it is so bright.
