On September 21, 1988, a major earthquake occurred in Taiwan, causing serious disasters in the central region. The "Chelungpu Fault Preservation Museum" in the 921 Earthquake Education Park reopened on May 31, 2013. It hopes to enhance the public's crisis awareness of earthquake disaster prevention by reviewing the surface ruptures and disasters along the Chelungpu Fault. This AR APP mainly uses "image recognition" to find designated images in the park and scan them, so that you can learn relevant knowledge about earthquakes. Let's follow the mascot "Tiantian" and go through the levels in the park!
