Abstract

Two difficult problems pertain to selection of an evacuation route
according to each individual's situation. One is constant supervision of
the situation of a living space and detection of dangerous situations;
the other is detection of residents' respective positions. In this
paper, we describe devices and systems for an indoor emergency
evacuation using a mobile terminal such as a cell phone or PDA for
indoor navigation. The navigation system functions autonomously: the
user's device receives wireless beacon signals from the surrounding
environment and can thereby detect a user's position by a mobile
terminal independently. In fact, no server-side computation is
necessary. Moreover, the system is applicable to an indoor emergency
evacuation system using various sensors. The emergency system navigates
people to safety in the wake of a disaster. A system must defect all
residents' positions and then inform them individually of routes to
safety to evacuate all residents to a safe space urgently. We have
developed a feasible indoor navigation system that can solve various
problems arising in the application layer.
