Ask any kid, playing in the sandbox is fun enough on its own, but too much moisture will turn your grainy playground into a lumpy mess. Researchers at UC Davis have cooked up one solution: an augmented reality sandbox. Much like last year's SandyStation, the project uses a Kinect sensor in conjunction with a digital projector and a bit of software to overlay topographical data and simulated water over a traditional -- and dry -- sandbox. The end result is an augmented environment that can be used to teach geographic, geologic and hydrological concepts. The team hopes the project will help them develop hands-on exhibits for science museums, teaching visitors about contour lines, watersheds, catchment areas and more. Check out the video above for a full demo, or scope out the source below for the technical nitty-gritty.
