説明
We developed position-dependent visible light communication using Digital Micromirror Device (DMD), which can display information for human and bit for sensors at the same time and the same position. In this paper, we indicate the purposes and relations between the our system and the other studies of ProCam at first. Secondly, we describe the basic idea how to communicate with visible light that depends on position. Thirdly, we developed an algorithm of embedding bit signals to control machines into static image such as a photo. This algorithm uses pulse width modulation (PWM) to express the tone of color with digital signals. These ideas are demonstrated using DMD that acts as the switch of light. We implemented the projector using DMD, and test the position dependent communication by visible light. Finally, as an application of this system, we implement a receiver and small display (8x8 LED dot matrix) module that can receive and decode the received projection light. As a result, we made sure that the position dependent visible light communication with DMD is suitable for the art and entertainment system.
