Abstract

Escape route signs provide orientation in case of emergency. However, these signs are static and guide people always in the same direction regardless of the actual situation. Dynamic escape route displays raise safety by redirecting people to an optimized route, e.g. by avoiding fire, areas with heavy smoke, congestions and blocked routes. We designed and prototyped an escape route system with the following characteristics: Use of wireless controlled e -paper displays (electrophoretic high-reflectance E Ink), fire detectors, cameras with artificial intelligence (AI) algorithms to identify the number of people in an area, persons lying on the floor, congestions (jams) and reduced visibility due to smoke and a system master controller. E-paper is bistable and therefore the default direction is always displayed even if no power is available. Thus, even if the dynamic routing system is down or not available, the safety is the same as for static signs.
