Police officers and other emergency responders have been using the Project54 system in their vehicles for many years. Over this time it is likely that certain trends have developed regarding how they use the system to make their daily tasks easier and safer. This thesis examines the use of human-computer interaction logging, post-processing and data visualization techniques to quantify and graphically present how police officers utilize the Project54 system. Specifically, data was retrieved from two deployed police cruisers that identified their use of Project54's speech user interface (SUI) and graphical user interface (GUI), as well as the vehicles' original hardware controllers. That information was then analyzed and five different sets of data visualizations were generated based on the analysis results. The visualizations were reviewed by eight members of the Project54 design team, whose feedback indicated that the visualizations were successful at relaying conclusive results from the quantitative analysis.
