Augmented reality sandbox lets you change the course of rivers, won't get you wet

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.
