This document proposes evaluating the usability of VALET, a visual analytics software developed by Purdue University's VACCINE lab for law enforcement officials. The project aims to collect user data through surveys, interviews, and recording user actions during goal-directed tasks. This will provide insights into difficulties with the current interface to propose design improvements around information scent, cognitive task analysis, and GOMS modeling. Future work would compare a new interface design to the current one through additional user studies and expert reviews.
