Hall of Simulation

The Augmented Reality (AR) Sandbox is an ideal tool to gain a better understanding of topographic maps. The display is made up of two parts–a large sandbox and connected projector. The sand can be used to shape a physical landscape and the projector automatically adjusts the projected map in real time to match the terrain.

The AR Sandbox was designed as a student project here on campus in 2018. After its completion, the team of students generously donated the project to the library, for future learners to use. The sandbox makes use of a sensor and projector to overlay an elevation map over the features of the sandbox. The sensor and subsequent code continuously updates the projection, allowing for real-time changes to be reflected on the surface of the sand.

The color-coding of the projection is representative of elevation changes. It ranges from warm tones to cool tones, descending in elevation from highest to lowest. Low areas will also be automatically filled with water, it appears dark blue with ripples on the surface. 

The AR Sandbox is designed to showcase the power of modeling three-dimensional structures (geographical features) into two-dimensions. Contour lines form concentric circles, each line representing an area of equal elevation. The closer lines are to one another, the steeper the change in elevation.

1. Use the provided shovel! It can be useful to quickly change the features shown in the projection.
2. Hovering your hand about a foot away from the sand will simulate a raincloud. This begins dropping simulated water over the topography. 
3. Play around with different shapes in the landscape. The simulation can usually match what you can imagine for it.
