There are now systems that automatically detect and highlight threats like knives and guns in X-ray images of passenger baggage (automated prohibited item detection system, APIDS).
CASRA conducted an experiment to investigate how APIDS affect how airport security officers analyze images in cabin baggage screening.
The eye-tracking experiment that we conducted aimed at the following questions:
- How much does an APIDS increase detection if it correctly highlights a threat?
- Is there a negative impact if the APIDS misses a threat?
- Could it be that screeners focus less compared to working without the APIDS?
Eye-tracking can provide important insights into the attentional processes and search behavior, e.g. how long screeners looked at the threat when working with or without the APIDS. Once we have analyzed the data, we are more than happy to share our results.
