Remember playing in the sandbox as a kid? How much fun it was to build castles and dig in the sand? Now researchers at UC Davis have created an augmented reality sandbox that let’s users manipulate the sand in real time to create flows of water and rivers. It works by overlaying a projected image of water over real sand while a hacked Kinect reads the topography and detects motion in the sand. The team hopes to use the device to teach people first-hand concepts about Geology and Hydrology in various science museums and exhibits. Check out the rest of this article here. What do you think? What are some of your favorite augmented reality executions?
