Study of dynamically user-changeable multiple infrared marker patterns

In this research, we study a multiple infrared marker pattern generation system that is dynamically changeable by the user. A user may be required to handle password generation such as hard token of one-time password. Therefore, we studied a dynamically changeable marker pattern generation system using multiple infrared lights. We developed a box-shaped light source that can emit four different wavelengths from one light source and implemented an IR filter on a slide bar to change the marker pattern. Marker pattern recognition accuracy experiments and communication speed experiments were conducted using this system. From the experimental results, it was confirmed that dynamic multiple infrared marker patterns were generated and the marker patterns could be recognized with high accuracy.
