This is a three-week project with Bloomington firefighters. In this project, we designed an information system for Bloomington firefighters to facilitate their information access and situation awareness.

What’s the Problem?
Interview & Secondary Research & Observation
Information gaps existing between what is necessary and what is available within firefighter’s currently systems can result in disastrous consequences.
Current system fails to provide critical information like weather, hazmat, hydrant location and floor plan.
Firefighters currently rely on the walkie talkie to communicate, which fails to provide in time information when emergency happens.
Firefighters do not have car-embedded GPS. Using phone to navigate could be difficult as they are wearing thick gloves. Also, they might want to know the traffic situation in certain routes to get to the site ASAP.
Firefighters cannot use GPS to conduct indoor navigation as GPS cannot get through the walls.
Kick Off the Problem
Information: Most of the information we used are in Firebrary, a part of the RESC.INFO repository.
Sensors: There has been researches attaching sensors to firefighters’ flame-resistant T-shirt. Sensors including heart rate sensor, humidity sensor, temperature sensor, and actis sensor.
Indoor Navigation: To locate the current position of the firefighter, we combining Radio Frequencies, Low-frequency Magnetic Fields, and Accelerators.
Outdoor Navigation: We could use Google Map API to implement outdoor navigation.
Computer? Laptop or Phone?
Primary Research & Secondary Research
Their current MDT system was embedded in computer. Considering computers are more suitable for serious work situation and touch screen may require changes in material of gloves, we choose to use computer as our platform.
How to Arrange the Information?
– Combination of Information –
As a information system, our design was trying to provide sufficient information for the captain, which made the alignment of information a critical issue. To achieve this, we studied the task flow of firefighter captain and decided on the system structure.
– Arrangement of Information inside Each Phase –
To minimize the cognitive cost and improving the learning curve, we followed the original information alignment as much as possible. So, we examined the original information presenting way.
