Abstract

This article proposes a real-time system that transforms shadows on a floor into colorful visual media. This system is based on the effect of complementary colors and multiprojection techniques. By exactly calibrating the system geometrically and photometrically, our system makes it possible to display images such as texture animation, colorful pictures, text, and live videos in shadows without any digitized artifact or latency. Since it can display any image, it is applicable for various purposes such as media art, entertainment, and advertisement.
