An interactive augmented reality coloring book

Creating entertaining and educational books not only requires providing visually stimulating content but also means for students to interact, create, and express themselves. In this paper we present a new type of mixed-reality book experience, which augments an educational coloring book with user-generated three dimensional content. We explore a "pop-up book" metaphor and describe a process by which children's drawing and coloring is used as input to generate and change the appearance of the book content. Our system is based on natural feature tracking and image processing techniques that can be easily exploited for other AR publishing applications.
