This week the U.S. Patent & Trademark Office published three patent applications from Google that cover an interactive book, a storytelling device and interactive page turning. It's clear that Google is eyeing the children's book market of tomorrow that will deliver a next generation interactive experience. While children books today include pop-up pages, the next generation pop-ups will be more interactive by including video projection, lighting projection, audio enhancements and even hints of using voice input to enhance the interaction of specific parts of the book. While Google's first iteration of the interactive book many not include holographic projection, you could tell that at some point in time this is where this invention is headed. The pico projector version of the first generation of interactive book will be aimed at the higher end of the market, according to Google.
