The augmented reality sandbox project at the Center for Geospatial Research is part of a four component system, aiming to bring together multiple technologies for cutting edge data acquisition, virtual/augmented reality and geovisualization for Earth Science education and research. These components are being integrated at the Department of Geography-UGA and create a unique 3D Immersion and Geovisualization (3DIG) experience. The 3DIG system and associated technologies promote increased interest in physical geography, geology and STEM related fields.
Using 3DIG, Earth Science concepts are taught by incorporating hands-on exhibit that provides an interactive environment for students to shape landforms by modifying the real sand in the sandbox. Two Microsoft Kinect 3D cameras capture and transmit the topography in the sandbox to a computer running simulation and visualization software. Results include terrain representations using color ramps and contour lines, as well as modeling of fluid-surface interactions such as water flow. This environment provides an extremely rich experience to students and researchers, who see in real time the results of their work. The system teaches geography, geology, hydrology and geomorphology, from basic map reading to the meaning of contour lines, watersheds, slope, and associated processes. Virtual reality goggles are integrated into the system for enhanced 3D experience and immersion.
The augmented reality sandbox framework was built in-house by Associate Director Dr. Sergio Bernardes and Research Assistant Andrew Knight. The sandbox was designed to hold 200 lbs of sand and can be transported to classrooms and laboratories. Software solutions incorporated into the sandbox include the AR Sandbox by UC Davis and the North Carolina State University Tangible Landscape. New developments are being incorporated into our implementation, including multiple in-house customizations.
Funds for the implementation of 3DIG and the augmented reality sandbox are being provided by The Center for Teaching and Learning at the UGA.
