Abstract
To realize an evacuation drill in which participants are expected to show their active roles, an experimental drill was conducted by instructing participants which way to go whenever they pass check points. The experiment of 75 student participation was done as part of a campus wide evacuation drill in which more than 3000 people were involved. Multiple routes were randomly selected and instructed on check points if they locate within an area where building collapses or fires might occur. According to our poll, 86% of the participants scored easy for maneuvering smartphone interfaces and 87% could follow the instructions correctly given by our system.
