Cyberchase Shape Quest is an augmented reality math app from PBS KIDS and THIRTEEN that exposes elementary-school children to three-dimensional immersive puzzle worlds, teaching geometry and engaging spatial cognition skills through the use of augmented reality (AR) technology. Designed for children 6-8 years old, the app features 3 games, Patch the Path, Feed the Critters and Hide & Seek. In Patch the Path, players to use a tablet device's camera and a printable game board to interact with 3D puzzles within five different virtual environments, over 30 different levels. While playing, children must engage their spatial memory, visualization, and planning skills to successfully complete each level of the game. In this demo, we focus mainly on Patch the Path, highlighting the game design and the roles of prototyping and formative research during development.
