I recently got the opportunity to help setup an Augmented Reality Sandbox. Written by some folks at UC Davis, the AR Sandbox is an interactive tool for teaching topographic maps. It consists of a projector and a Microsoft Kinect mounted above a ~3×4 foot sandbox. Using depth information from the Kinect, the topography of the sand is scanned, and the correct contour lines are projected onto the sand’s surface.
The software consists of a VR toolkit, a Kinect driver, and the Sandbox itself, all of which are open source (GPL v2). So far, we’ve successfully installed it on Linux Mint and Fedora. Massive thanks to the guys at UC Davis for making a great teaching tool, and for releasing it open source.
And yes, it is exactly as much fun to play with as it looks.
