Augmented reality is superimposed on the real world. In the case of the AR sandbox, the projection system is overhead. As the user moves sand around the sandbox, the projector's software updates the projected image in real-time, turning mountains into molehills, and filling valleys with sand.
As water is poured into the sandbox to simulate rain or flooding, the software uses the topographic data to calculate the flow of the water. The simulated liquid then flows downhill or accumulates in lower areas just as it would in real life.
Using an AR Sandbox is highly engaging and provides a multi-sensory learning experience. Users can see the results of their actions immediately and can experiment with different scenarios to observe how they affect the landscape and water flow.
The interdisciplinary sandbox is especially useful in geography and Earth Science education as well as physical sciences and environmental studies. It supports place-based learning and inquiry-based exploration. It has also practical uses in planning and environmental management.
