Sony's interactive book technology for the PlayStation 3, Wonderbook, which will power games like Book of Spells and Diggs: Nightcrawler, is a result of technology that began in the early days of PlayStation 3, the company revealed in a video today on the European PlayStation blog.

"We had some technology for tracking markers, usually a mark on a card," said Diarmid Campbell, London Studio's head of computer vision. "And there were two game concepts in the running. One was a virtual pet, and one was an augmented reality book."

The first product to use the technology was EyePet, which uses the PlayStation Eye camera to create virtual pets. When creating Wonderbook, London Studio used the same marker technology to bring the interactive books to life.
