Adaptive Computer-Based Training Increases on the Job Performance of X-Ray Screeners


Schwaninger, Adran; Hofer, Franziska; Wetter, Olive Emil (2007). Adaptive Computer-Based Training Increases on the Job Performance of X-Ray Screeners. In: 41st Carnahan Conference on Security Technology, Proceedings, Ottawa, Canada, 2007 - 2007, 117-124.

Abstract

Due to severe terrorist attacks in recent years, aviation security issues have moved into the focus of politicians as well as the general public. Effective screening of passenger bags using state-of-the-art X-ray screening systems is essential to prevent terrorist attacks. The performance of the screening process depends critically on the security personnel, because they decide whether bags are OK or whether they might contain a prohibited item. Screening X-ray images of passenger bags for dangerous and prohibited items effectively and efficiently is a demanding object recognition task. Effectiveness of computer-based training (CBT) on X-ray detection performance was assessed using computer-based tests and on the job performance measures using threat image projection (TIP). It was found that adaptive CBT is a powerful tool to increase detection performance and efficiency of screeners in X-ray image interpretation. Moreover, the results of training could be generalized to the real life situation as shown in the increased detection performance in TIP not only for trained items, but also for new (untrained) items. These results illustrate that CBT is a very useful tool to increase airport security from a human factors perspective.
