Since our societies have diverse people and built environments, studies must be needed to develop systems assuring people's safety in potential emergent situations. We have developed a multimedia guidance system available in evacuation. In this paper, we compared the guiding effectiveness of three spatial information presentations: (1)the arrow indicating the direction of movement, (2)the floor-plan map with the present place and the exists, and (3)the map with the suggested route from the present place to the nearest available exit. The results showed that the third was the best in giving successful guide and spatial knowledge to the subjects.
