Researchers in Korea have created a children’s book that uses 3-D technology to bring its characters to life.

“It took us about three years to develop the software for this,” lead researcher Kim Sang-cheol told Reuters. “It will take a while to market this technology to the general public.”

In video demonstrations of the technology, both text and animated figures emerge from the page and interact as the book is moved.

To experience the effect, readers wear computer-aided goggles that translate the images into three dimensions.

According to Reuters, the Korean team first hopes to develop the technology for everyday use in cellphones.
