Abstract
An virtual placement supporting system of furniture using AR (Augmented Reality) and an algorithm of using other makers for the AR at the same time are presented. The AR is technique for emphasising the video image which was taken with web camera, by putting the CG on a video image. The furniture as 3DCG is placed in a real space by the AR, through the web camera. By using this proposed system, it is more effectively imagined that arrangement of the furniture, than imagining in a head. The furniture which is heavy like a bed, can be easier move as the 3DCG in the real space by only moving a paper printed the marker corresponding to the bed.
