Interactive illustration of collage for children with folktale e-book

It is always challenging to teach children foreign languages, due to the difficulty of learning and their short attention span. To address the challenge and take advantage of the popularity of touchable tablets and smartphones, we propose an educational folktale e-book (EFE-Book) application with an interactive illustratable tool. EFE-Book is developed to teach preschool children to learn foreign languages by telling folktales with illustrations. To encourage effective learning, EFE-Book provides an interactive collage tool that enables users to create collage-based illustrations by hand. We propose a Voronoi diagram based approach to model paper tiles for the development of EFE-Book. With EFE-Book, the user can create colored paper tiles and attach them to the predesigned sketch through touch interface, such as Apple iPad.
