RESEARCH AT CASRA
Applied, interdisciplinary, and holistic
Our research goal is to strengthen security and facilitate the flow of goods and people at airports and other environments where humans and machines interact. Our applied and interdisciplinary research is conducted in close collaboration with end users, airports, and regulators. We analyze, evaluate, and design systems using a holistic approach by taking into account interactions between humans and technology.
Our main research areas are “human factors and performance”, “human-machine interaction and systems” and “cognitive and computational modeling”. We also have a strong record of accomplishment in national and international research projects including several EU projects. We provide our knowledge to society through publications in scientific journals and by contributing to conferences and expert groups.

HUMAN FACTORS And Performance
![](https://www.casra.ch/wp-content/uploads/2019/05/Images_v010_Research_HumanFactors_Performance-e1566227869527.jpg)
Performance of security screening depends strongly on human factors. Important determinants are pre-employment assessment, computer-based training, certification, and operational performance measurement.
HUMAN FACTORS And Performance
Despite advances in technology, aiport security officers (screeners) are still indispensable in X-ray screening of passenger bags and other items. Our research addresses key topics of human factors and performance: pre-employment assessment, computer-based training, certification and operational performance.

Pre-employment assessment
Our research on X-ray screening has shown that not everyone has the potential to become a good screener. With our tests for selecting screeners, we can identify persons who have the necessary abilities before employing them. In our current research, we investigate whether different visual cognitive abilities are needed when operating single, multi-view and 3D imaging for X-ray screening of passenger bags.
Computer-based training
Computer-based training is very important to achieve and maintain good detection performance of X-ray screeners. In our research on training effectiveness, we could show that individually adaptive training using a large and representative image library is the key to success. In current research projects, we examine training challenges and solutions for operating multi-view and 3D imaging systems.
Certification and operational performance
Initial and recurrent certification of screeners is mandatory in airport security screening and in other areas. Based on several years of research, we have developed computer-based tests that are reliable, valid, and standardized. We have also conducted research on operational performance measurement using covert tests and threat image projection. Current research investigates potential impacts of new screening technology on certification procedures.
Human-machine interaction and systems
![](https://www.casra.ch/wp-content/uploads/2019/05/Images_v010_Research_humanMachineInteraction-e1566227796970.jpg)
Performance in security screening depends on humans, machines and their interaction. In our research on human-machine interaction, we examine different X-ray image display technologies (e.g. 2D vs 3D imaging), automation to support X-ray screeners, and how security checkpoints could be improved as sociotechnical systems.
Human-machine interaction and systems
Performance in security screening depends on humans, machines and their interaction. In our research on human-machine interaction, we examine different X-ray image display technologies (e.g. 2D vs 3D imaging), automation to support X-ray screeners, and how security checkpoints could be improved as sociotechnical systems.
X-ray image display technologies
Older X-ray machines show passenger bags only as a single view. Newer technology shows bags from two different viewpoints (multi-view imaging). The most recent technology is based on computer tomography, which provides 3D rotatable images. In our research, we compare different image display technologies and provide recommendations on how to improve human-machine interaction.
Automated threat detection in X-ray screening
Material based automated detection of explosives is the standard in hold baggage screening and increasingly used in cabin baggage screening. Shape based automated detection of other threats (e.g. guns and knives) are becoming available. In our research on automation, we analyze how to implement such systems for increasing human-machine system performance.
Improvement of security checkpoints
Security checkpoints can be regarded as sociotechnical systems where humans and machines interact with each other. We analyze current checkpoints using qualitative and quantitative methods. With 3D computer simulations and large amounts of data, we explore how to improve effectiveness, efficiency, and passenger experience in security screening.
Cognitive and computational modeling
![](https://www.casra.ch/wp-content/uploads/2019/05/Images_v010_Research_Cognitive_ComputationalModeling-e1566227739109.jpg)
We use cognitive and computational modeling for understanding X-ray image difficulty and visual inspection as search and decision making. In earlier research, we used cognitive and computation modeling for face recognition and scene perception.
Cognitive and computational modeling
We use cognitive and computational modeling for understanding X-ray image difficulty and visual inspection as search and decision making. In earlier research, we used cognitive and computation modeling for face recognition and scene perception.
Automated X-ray image difficulty estimation
Prohibited items are more difficult to recognize when depicted from unusual viewpoints, when superimposed by other items and when placed in visually complex bags. We have developed algorithms that estimate image difficulty resulting from these image-based factors.
Visual Inspection
Visual inspection has been investigated in different areas and described as visual search and decision making. In our research, we have shown that such a two component model of visual inspection can also be applied to describe the task of X-ray screeners.
Processing of faces and natural scenes
Faces have different components (eyes, nose, mouth, etc.) with a specific spatial relationship (configural information). In our research, we have investigated how such information is processed in upright and inverted faces. We also investigated how people process visual information of natural scenes in order to categorize them and evaluate scene typicality.

Selected projects and latest news:
Target Recognition using Artificial Intelligence (TRAI)
Description |
The project “Target Recognition using Artificial Intelligence” (TRAI) evaluates chances and risks of AI systems for the automated detection of prohibited items in X-ray images (APIDS). Currently, first such systems are commercially available. These systems have a big potential to increase security in aviation. However, it is still unclear how well they actually perform for different threats and how the interaction between APIDS and security officers should be designed for optimal security and efficiency. TRAI aims at providing answers to these questions. |

OSARP Training Study
Description |
Computer-based training for X-ray image interpretation is mandatory for airport security screeners and is used at airports all over the world. Current training systems are focusing mainly on visual knowledge, i.e. what objects are forbidden and how do they look in an X-ray image. A useful addition for the recognition of bombs in X-ray images of hold luggage could be so called On-Screen-Alarm-Resolution-Protocols (OSARP). In OSARP training, the screeners learn how to use certain rules for optimal X-ray image interpretation and certain heuristics for a better decision process. |
