Noticeable Exit / Emergency exit

Emergency exit we have nowadays seems perfect, but it works properly only if we find and follow them. What if it’s hard to find due to the smoke and can’t see any farther? Or What if we are blind? Here are three system that will help people find the exit.
1. Exit Indicator is designed to show the exit not only in an emergency, but also normal times. It shows the arrow by built-in laser pointer.
2. Corner Helper is an attachable arrow that people can touch and see it. The corner is the biggest barrier when we look for the way to the exit.
3. Noticeable door is designed to help people find the exit door easily by the big pictogram on the door.
