X-Ray Tutor (XRT) is a scientifically based training program, specifically designed to increase the detection of prohibited objects in X-ray images.
It has been developed by vision and computer scientists of the Visual Cognition Research Group (VICOREG) at the University of Zurich in collaboration with airport security experts.
At the heart of X-Ray Tutor are results from scientific studies on how the human brain processes visual information in order to recognize objects from different viewpoints (Schwaninger, 2004b; for recent overviews on object recognition see Graf, Schwaninger, Wallraven & Bülthoff, 2002; Schwaninger, 2005a).
The scientific theories, combined with adaptive learning algorithms, create the world's only scientifically based, individually adaptive x-ray object recognition training program. X-Ray Tutor is currently used by some of the largest security organizations in the world. The United States Transportation Security Administration (TSA) is using X-Ray Tutor at over 400 airports across the country since spring 2004 as part of its recurrent training and professional development program for airport security screeners (subcontract with Safe Passage International through Lockheed Martin Inc.). The Canadian Air Transport Security Authority (CATSA) uses X-Ray Tutor at several airports in Canada as part of a large research project with the University of Zurich on X-ray image tutoring technology for aviation security screeners. X-Ray Tutor is operational in Switzerland since 2002, at 17 airports in Germany since 2003, and in several other countries such as Australia, Belgium, Bulgaria, Greece, Korea, Latvia, New Zealand, and Portugal. For more information on X-Ray Tutor see Schwaninger (2003c, 2004a, 2004b).
