In emergency circumstance (such as earthquake, flood, air attack and etc.), devices may break down. Taking Wuhan City of China as an example, majority of people are not capable to distinguish directions and arrive shelter quickly. What is worse, most citizens do not know locations of shelters. Thus, I design a navigator for those situations with Agumented Reality in order to offer users a simple and direct way finding to shelters

在紧急情况（例如地震、洪水、空袭等）之下电子设备会出现失灵。以中国武汉为例，绝大部分人无法分辨方向并且快速到达避难点。更严重的是，大部分的市民并不知道避难点的位置。因此，我设计了一个增强现实的导航来解决这类问题，为用户提供简单且直接的寻路导向。
