The Augmented Reality Sandbox

posted by Jason Kottke   Feb 19, 2019

Inspired by a Czech project, a team at UC Davis is building an Augmented Reality Sandbox that lets you create & study different landscapes by moving real sand around in a real sandbox. Check this out — the topographic lines and colors change in realtime as you move the sand around:

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.

That video is from several years ago…here’s a more recent video showing a hybrid AR/VR sandbox setup:

The software is available to download so if you want to build your own, go for it. (via a map a day)

Notable Women

As Treasurer of the United States in the Obama administration, Rosie Rios pushed hard for the inclusion of more women on US currency, culminating in the selection of Harriet Tubman for the new $20 bill. But with many more amazing women left on the list for inclusion on currency, Rios partnered with Google to create Notable Women, an augmented reality app that puts an historic American women on any US bill you hold up to your phone’s camera. Here’s how it works:

The app’s tagline is “swapping out the faces we all know for the faces we all should” and is available on iOS and Android. You can also view the modified notes on the website, like Sojourner Truth, Madam C.J. Walker, Margaret Bourke-White, and Maria Mitchell.
