Concealment-Type Disaster Prevention Information System Based on Benefit of Inconvenience

摘要

Using a hazard map and disaster-preparedness system during normal times is typically recommended to cope with a disaster appropriately and promptly. However, a hazard map has the possibility of information overload and the disaster-preparedness system has a low utilization rate. For increasing the users of the disaster-preparedness system, an approach different from the conventional disaster prevention system is required. The proposed system "Crimap" presents only the information near the user on the map and hides the outside of the surrounding. Thus, we can reduce the amount of information and create awareness of the disaster-preparedness information in daily life. This is based on "benefit of inconvenience." It is inconvenient to not see the whole map. However, it is "useful" to be aware of the disaster-preparedness information. From the usefulness verification experiment of the map concealment, we found that the participants were able to recognize the information presented by reducing the amount of information.
