description Motor vehicle crashes are one of the leading causes of emergency medical service (EMS) fatalities. These crashes have been mainly attributed to driver distraction caused by in-vehicle technologies especially mobile computer terminals (MCTs). This study used cognitive performance modeling to assess MCT use by EMS drivers. A pilot study was conducted with six EMS experts performing a navigation task with the MCT. Pilot data results were used to create and validate the models using CogTool platform. In terms of task completion time (TCT), the model closely matched the data collected through observations, allowing for redesign improvements to be considered, while further validating CogTool as an analytical tool. The MCT was also redesigned based on the usability heuristics. The developed models and approach can be used in MCT design and development process to ensure efficient interaction in multi-tasking situations of driving and using the MCT.
