Technicians funded by the Alaska Experimental Program to Stimulate Competitive Research (EPSCoR) have developed an "augmented-reality sandbox" to interest the public in geography, geology and other fields. The sandbox lets people create mountain ranges and bodies of water with their hands.

As they generate these geographic landmarks, an overhead projector turns their hills and valleys into a colored topographic map projected on the sand. This approach allows users to see how topography lines change as the landscape changes. However, the sandbox, created by researchers with the Geographic Information Network of Alaska (GINA), and based at the University of Alaska, Fairbanks, does more than just add colors and contour lines. When users hover their hands over the sandbox, it interprets the movement as a cloud and virtual rain drops onto the landscape, creating channels in the valleys.

To construct the sandbox, the team, led by Eric Stevens, used open-source software and parts based on a project by a faculty member at the University of California, Davis. The group unveiled their creation at the 2014 Alaska Conference on Surveying and Mapping in Fairbanks. It is now used as an outreach tool to engage the public in science and to demonstrate GINA research. In the future, the GINA team plans to build a mobile version of the sandbox to take to science fairs and museums.
