In the early stage of planning or design, it is desired to support the informal communication between remote sites. In this study, informal communication environment between remote places was constructed by using the interactive tiled display wall.This system measures the user's gesture as well as captures the user's image by using the multiple fish-eye cameras. Then, the remote users can communicate with each other by using the touch interaction in the shared space. This system was applied to the remote communication and the effectiveness of this method in the informal communication was experimentally evaluated.
