Abstract

This study was concentrated on which way is the most convenient for firefighter to get information, comparing among audio display, text display, and combined multi-modal display. Can fire commanders effectively obtain key fire information while they are en route to the fire, especially when they sitting in a moving and bumpy car? The task includes free-browse, free-recall and searching information. The result showed that: (1) Audio only always made firefighter taking the longest time to browse and search, but the introduction of audio display made the two combined displays more quickly to access information, and more easy to remember. (2) Searching in a moving environment took a little longer than searching in lab. (3) Comparing in the lab and in moving car, it was found that searching in a moving environment took a little longer than in lab. (4) It was proved that text display was still a necessary and indispensable way to display information.
