| Outline of Final Research Achievements |
In this research, we developed a novel marker that can multiplex information on a physically single plane. The proposed marker consists of several infra red light cut filters (IR-filters), each of which has different threshold of transmitting wavelengths. These IR filters were arranged in matrix form and set inside the marker. When the marker is illuminated by an infra red light, a pattern appears in a form of shadows invisible to the human eye, and the pattern changes when the marker is illuminated by another infra red light with different wavelength. Since the marker is stackable, the user can easily change the marker pattern. As applications of the marker, we implemented two prototype systems. One is an optical certification device and the other is a wall-shaped interactive surface system. In addition, we created several interactive art systems that utilize the proposed mechanism.
