Use of Active Test Objects in Security Systems
Some modern security systems use pupillometry to identify people in a state of drug or alcohol intoxication. Our work is aimed at developing an optoelectronic system to search for people who represent a hidden threat. We propose in security systems to use test objects that are significant only for a certain category of people. Other people will not have a reaction to the test object. Synchronous registration of pupillograms and oculograms allows to determine the deviation of the emotional state from the original. Oculograms specify the detail of the test object to which the reaction occurred. We experienced the idea in the older age group (45–50 years old) under ideal conditions (the pupil is clearly visible). In the future we plan to expand the age range and increase statistics. Experiments have shown that the use of thematic images as test objects allows the pupil to cause a reaction that is greater than that caused by other factors. Synchronization of pupillograms and oculograms indicates the centers of attention and indicates the presence (or absence) of emotional attachment.
