Contemporary aging and international societies have to respond to various needs of users whose traits are diverse. As to built environments, their size has been larger and larger, and purpose and usage of them have become more varied and complex. Accordingly, studies must be needed to develop systems assuring people's safety in potential emergent situations. From this point of view, we are trying to develop a mobile multimedia guidance system available in evacuation. And we made an experimental study to examine the effects of pre-learning and guide-information on evacuation behavior. It shows that walk-through tends to be effective pre-learning. As for guidance information type, arrow information is effective for evacuees. Though route map information does not facilitate evacuation behavior, it seems to provide evacuees sense of security, suggesting present position in the spatial layout as a whole.
