Webcam Augmented Reality
In this, the first Jim Henson Company online augmented reality experience for preschoolers, kids can hatch a baby dinosaur from an egg, and interact with it by pressing virtual buttons on a printout that they present to their webcam. Developed with Ogmento for The Jim Henson Company. Utilizes natural feature tracking, which eliminates the need for a black and white fiducial marker.
