June, 2025: Experiment on How APIDS Affect Image Analysis

New systems can now automatically detect and highlight threats such as knives and guns in X-ray images of passenger baggage (automated prohibited item detection systems, APIDS). CASRA carried out an experiment to examine how APIDS influence airport security officers’ image analysis during cabin baggage screening. Using eye-tracking, we gain insights into attention and search behavior, including how long screeners fixate on threats with and without APIDS. We will share our findings once the data analysis is complete.
