Sorry if it's not clear - the visual angle is used in all sorts of research into vision. The researchers of this particular exhibit use it to find out how we look at items on a computer screen. Their results help them devise better ways of displaying the information from x-rays, for example through 3D screens, which will make airport staff's task of searching for several kinds of items at the same time easier.
