We have conducted a study to develop portable navigation equipment for lower grade students and a system to direct evacuation routes to the students who are left in school buildings. Particularly, we have paid much attention to development of an interface design in the software suitable for students and teachers quick and accurate judgments. In this study, we have researched to discover characteristics of cognitive judgments on the interface by adopting an experimental method. In study 1, we investigated the contents of the navigation equipment of the commercial products. As a result, it was hard to extract necessary information because there was too much complexity. In study 2, we examined a navigation simulator for teachers to help students evacuate from school buildings. It was easier for teachers to plan and input evacuation routes on a simulator with 2D images than that with 3D ones. In addition, we continue the experiment by an AR simulator for lower grade children.
