The Carpets with Indication Function
A very common thing can turn into something very special with a few changes. Carpets are quite common. But this invention is quite different. It can guide people through complicated buildings. Have you ever been to a mall such gigantic that you it would take a whole week just to visit all the floors? It is very easy to get lost. This carpet can solve the problem. When someone steps on the first LED bar on the carpet, it would send a signal to the second one, lighting it up, then to the third one, and so on. This can also guide people through dark rooms without turning on the lights. The device is very thin so the bump is less likely to trip people. The lines can be guided to a central control box. The main switches would be in there. All you have to do is sort the lines and plug it in. Installation is pretty easy.
