Abstract

In this paper we propose the LED array projector that project invisible information for small embedded device. Each pixel of this projector has own LED light source which can easily modulated by high frequency signal. In this system, projector send the image to the human's eye and invisible information to the embedded device. For example, each pixel can send positional information and different video signal. We develop a proto-type projector which has LED array of 5 pixel width and 4 pixel heights.
