Article Synopsis
- Airports worldwide are transitioning from traditional 2D dual-view X-ray screening to advanced 3D computed tomography (CT) screening for baggage, enhancing target detection through interactive image manipulation.
- A study with 695 participants in February 2023 revealed that interactive search led to higher accuracy rates and longer reaction times compared to dual-view search, supporting the effectiveness of 3D CT technology.
- Though time on task influenced reaction times and response tendencies, there were no significant differences in these effects between the two screening methods, emphasizing the overall advantages of interactive search for airport security.
In this study, we propose a new approach to the perceptual representation of object colours. Three-dimensional objects have a polychromatic colour distribution. Yet, human observers abstract from the variation along the three perceptual colour dimensions when describing objects, such as when we say, "a banana is yellow".
