Emergency tends to make people panic. In chaos, people are extremely easy to get out of order, which will make it even harder to escape from disasters. By adding a special membrane to the ordinary 3D glasses, we are able to get two types of 3D glasses, one of which can be used for detecting the ultraviolet light and the other for the infrared light.

These glasses will be given to different audience, according to their seat. The glasses will guide people to follow two different, pre-determined escaping routes in emergency.
