Overview Firefighting 101 Firefighting Difficulties Our Solution Representative Firefighting Tasks Design Evolution through Iteration Demonstration of FireWall’s Final UI Conclusion

Firefighting 101 Fire is called in to contacts the appropriate fire station Firefighters go to fire location One of the firefighters becomes temporary incident commander Firefighting chief arrives later, becomes IC

Firefighting Difficulties Firefighting Preparation Site information is unavailable Knowledge of fire status often vague Monitoring Status of Firefighters Firefighter location, amount of oxygen, and physical status is vague, relies on radio contact Firefighting Organization Task management system uses combination of memory and whiteboard system

FireWall: A Digital Whiteboard Command Post Firefighting Preparation Provides important site information Thermal imaging shows fire status Monitoring Status of Firefighters Displays firefighters’ locations Monitors firefighters’ oxygen amounts and body temperatures Firefighting Organization Supports task assignment and timing

What’s Missing Precise thermal imaging Firefighter real-time location monitoring Blueprint system

Representative Firefighting Tasks Task #1: In Transit Learn about the site of fire Brief the firefighters about situation Task #2: Arrival On Scene Determine available resources Assign firefighter tasks Task #3: Firefighter In Danger Receive an alert that firefighter is in danger Determine status and location of firefighter in trouble Take measures to rescue downed firefighter

Design Evolution through Iteration: Contextual Inquiry Interviewed firefighters at one of Berkeley’s fire stations Changed initial project direction Personal firefighter assistant Command post

Design Evolution through Iteration: Lo-Fi Prototype From sketches constructed initial interface Tested on Oakland firefighters

Testing the Low Fidelity Prototype

Compensation for User Tests

Oakland User Test Results Interaction Problems Button bar Site info Personnel detail

Design Evolution through Iteration: Hi-Fi Prototype and Heuristic Eval. Developed first hi-fi prototype using Macromedia’s Director 8 Underwent peer Heuristic Evaluation

Changes: Lo-fi to Hi-fi

Heuristic Evaluation Results Poor Visuals Clickable buttons Cluttered map Tabbed Personnel Shaded regions

Design Evolution through Iteration: Hi-Fi Prototype Version 2 Developed second version of hi-fi prototype Tested on Richmond firefighters

Changes: Hi-fi v.1 to Hi-fi v.2

Richmond User Test Results More Features Timed tasks Additional task Improved danger notification

Demonstration: FireWall’s Final UI

Conclusion Summary: Firewall is a system that provides information management to firefighting incident commanders FireWall for CS160 Importance of contextual inquiry Value of design iteration FireWall for Incident Commanders "The system that we have doesn't work that well.” – Oakland firefighter Special thanks to the Berkeley, Oakland, and Richmond fire departments.
