In many densely populated places today, the safety exit signs are only posted on the corridor wall, directly above the door, and on the floor.
The signs posted on the floor, because of the frequent flow of people, most of them will be worn out and cannot play a good role.
The wall and door top signs, the area is very small, when the danger occurs, there is no way to play a good role in the prompt, and in a hurry, people have to look for the wall prompt standard, not only a waste of time, but also because of the pace of the search pause and a lot of unexpected danger.

My idea is to design a holographic projection equipment. When danger occurs, the projection will quickly design the fastest and most convenient path to the safe exit according to the specific location of the person. At the same time, it will also prompt the disaster site so that the rescue personnel can quickly find the way to rescue.

Using the simple pattern of arrows, people can understand the route position and direction faster, using red and green colors to distinguish between safe areas and dangerous areas.
