The authors have researched a support system of the reminiscence and life review activity. This support system consists of an interactive tabletop display and interface system. Many interaction systems are proposed until now. An invisible code is one of the useful technologies for a computer interaction. The invisible codes provide us with an operating environment using a pen-like device. However, this technology is applied to the only paper media. The authors think we want to realize an interaction using the invisible code on an electrical media. In this paper, we propose a method to display invisible codes using LCD panels and to detect a polarized symbol image with a conventional CCD camera. © 2009 Springer.
