AUGMENTED REALITY SANDBOX

From the https://arsandbox.ucdavis.edu/:

“A hands-on sandbox exhibit combined with 3D visualization applications created by researchers at UC Davis.

Simply mold the sand by hand and the landscape comes to life! The sand is augmented in real-time with an elevation color map, topographic contour lines, and simulated water.”

This sandbox has been designed and created by SPACECO, Inc., a surveying and engineering firm based in Rosemont, Illinois. They utilizing the basic format / programming developed and published by the W. M. Keck Center at University of California - Davis and utilized aircraft-grade aluminum extrusion tubing to construct the box, cart and video arm.

Hardware Requirements

• An AR Sandbox requires the following hardware components:

• A computer with a good graphics card, running any version of Linux. The AR Sandbox software, in principle, also runs on Mac OS X, but we advise against it. We strongly recommend using desktop computers over laptop computers. For one, laptop computers powerful enough to run an AR Sandbox are typically more expensive than desktop computers of comparable power; second, laptop computers with high-end Nvidia graphics cards often contain so-called Nvidia Optimus technology to reduce system power usage by dynamically switching between the high-performance discrete graphics processing unit (GPU) and the main CPU's low-performance integrated graphics processor (IGP). Optimus is not fully supported on Linux and may prevent access to the discrete graphics card entirely.

• The AR Sandbox does not run under Windows, and neither does it run from within a virtual machine. It either requires a PC exclusively running Linux, or a dual-boot setup with Linux and Windows.

• A Microsoft Kinect 3D camera. The AR Sandbox software, or rather the underlying Kinect 3D Video Package as of version 2.8, supports all three models of the first-generation Kinect (Kinect-for-Xbox 1414 and 1473 and Kinect for Windows). All three are functionally identical, so get the cheapest model you can find. Note: The second-generation Kinect (Kinect for Xbox One or Kinect for Windows v2) is experimentally supported by the AR Sandbox software as of version 2.4, when using version 3.4 of the Kinect 3D Video Package.

• A digital data projector with a digital video interface, such as HDMI, DVI, or DisplayPort.

• A sandbox with a way to mount the Kinect camera and the projector above the sandbox.

• Sand.

Background:

UC Davis' W.M. Keck Center for Active Visualization in the Earth Sciences (KeckCAVES), together with the UC Davis Tahoe Environmental Research Center, Lawrence Hall of Science, and ECHO Lake Aquarium and Science Center, is involved in an NSF-funded project on informal science education for freshwater lake and watershed science. As part of this project, we are primarily developing 3D visualization applications to teach earth science concepts, but we also built a hands-on exhibit combining a real sandbox, and virtual topography and water created using a closed loop of a Microsoft Kinect 3D camera, powerful simulation and visualization software, and a data projector. The resulting augmented reality (AR) sandbox allows users to create topography models by shaping real sand, which is then augmented in real time by an elevation color map, topographic contour lines, and simulated water. The system teaches geographic, geologic, and hydrologic concepts such as how to read a topography map, the meaning of contour lines, watersheds, catchment areas, levees, etc.

This project was inspired by a video created by a group of Czech researchers, who demonstrate an early prototype of an AR sandbox with elevation color mapping and some limited form of fluid flow. There is an even earlier project, Project Mimicry, of which we learned only later; it also appears to only be in early testing phase. For full description and documentation, see UC Davis - KeckCAVES.
