Using AR and Unity 3D to Support Geographical Phenomena Simulations

An AR and Unity-based simulation system for geographic phenomena is constructed to address the problem that students have difficulty to understand complex and abstract geographic phenomena due to the traditional didactic teaching method used in geography classroom teaching currently. A three-dimensional electronic sandbox is developed in this research, which can simulate realistic terrain and displays contour lines according to the shape of the sand in the sandbox. It also recreates geographical phenomena in nature such as rainfall, sea changes, floods receding, volcanic eruptions, etc. realistically.
