Implementation and Evaluation of Unified Disaster Information System on Tiled Display Environment

In the event of large disaster, local government will be charged of responsible activity over counter disaster operation. However, conventional procedure for understanding and sharing of disaster information at the headquarters is performed by paper-based documents and indication on paper-based map, it could be difficult to represent of understanding of disaster statuses for multiple headquarters personnel. This paper proposes design and implementation of disaster information system based on ultra high definition display environment using GIS. We have designed the system consists of large and ultra definition display environment as unified shared display at headquarters. Our system considers to implement directly status reporting function, detachment of displaying location and media content and user-system interaction method using smart devices as content controller. We had hands-on based experiment in order to assess usability of our system. The result shows relatively positive feedback for usability of the system by participant consist of non-specialist for counter disaster activity.
