Multi-Projection System for Transforming Your Shadow into Colorful Visual Media by Means of Complementary Colors

Abstract

This paper proposes a real-time system transforming your shadow on a floor into a colorful visual media. This system is based on the effect of complementary color and multi-projection techniques. A user occluding the projector light may create an undesirable shadow in front-projector-based systems. We overcome and turn this problem into our advantage with an elaborately designed optics including multi-projection techniques (geometrical and photometrical alignments), so that our system makes it possible to display colorful textures, colorful pictures, sharp characters, and even a movie in your shadow.
