This paper presents a computer-based system for a fire incident response information support system (FIRISS). FIRISS is designed to allow contextual information sharing among a firefighting response team during a fire emergency. The FIRISS is implemented using Microsft .Net tools with Visual basic as the primarily software driver. The interface is intuitively easy to use with information with of menu icons for weather conditions, telephone dial pads, capability for broadcast and play-back of videos, and dialog boxes for textual communication. Thematic knowledge in human-computer interaction, cognitive systems engineering, and visual analytics are used.
