Discerning the humans emotional instability using pupillography

M. Boronenko, O. Ovsyannikova, V. Zelenskiy

Abstract: Modern emotions discerning biometric systems that are currently developed are passive and aim at identification of psychological state of a human from his/her mimics. Existing systems successfully recognize basic emotions by facial expressions and determine drug and alcohol intoxication by “glassy eyes”. However, the task of establishing a link between the emotions experienced and possible subsequent actions is yet unsolved. This happens as the size of the pupil strongly depends on the illumination and the uncertainty of the initial state of the pupil. The aim of the work is to describe a method of active recognition of emotions, based on the evaluation of pupil size against time during active testing. Test objects assume a form of audio or video information; the pupillography is recorded as the subject reacts. The idea behind selection of test objects dictates that the reaction to them should significantly vary between ordinary and potentially dangerous peoples. The article presents the first results. Video and audio files developed for the investigation of the pupil reaction to the information received by brain allows to evaluate the stability of the emotional state of a person. The results will allow to create a system of active recognition of individuals, who pose a potential danger to the society.
