APPLICATION OF EYE-TRACKING TECHNOLOGY DUAL EYE TRACKING (DUET) IN THE STUDY OF COOPERATION BETWEEN CHILDREN WITH ATYPICAL DEVELOPMENT AND ADULTS IN THE LEARNING PROCESS

Abstract

A technological breakthrough in simultaneously tracking the visual behavior of two people with an eye tracker (DUET) allows you to explore how a child perceives the world and how an adult (teacher) infl uences it. It became possible to more objectively trace the transformation of a child’s perceptual processes under the infl uence of learning (Monroy, Chen, Houston, Yu, ). An analysis of the gaze movements allows us to model the learning process as the emergence and dynamic transformation of an intersubjective connection between the perception-action systems of a child and an adult (Shvarts, ). Synchronous registration of the dyad’s eye movements was carried out by two portable trackers in the form of Pupil Headset goggles. A comparative study was carried out on a sample of preschoolers - years old: typically developing children and children with hearing impairment after cochlear implantation (sensoneural hearing loss, ICD- class H). An analysis of the ways in which the gaze of the adult-child dyad moves makes it possible to model the learning process as the emergence and dynamic transformation of an intersubjective connection between the perception-action systems of a child and an adult. Comparison of gaze patterns showed that contrasting groups of children use different perceptual strategies in the learning process: the specifi city of eye movements of contrasting groups is manifested in the perceptual actions themselves and the pattern of eye movements relative to fi xations in relevant areas corresponding to the task. It was found that the oculomotor activity of an adult changes in the process of interaction with children of contrasting groups and is organized taking into account the specifi c features of the child’s perceptual activity. Differences are manifested in the degree of synchrony of fi xations and the similarity of the trajectories of gaze movements of an adult and a child. An important result of using the DUET technology on contrast samples is the fact that the process of teaching/ learning caused a mutual transformation of the perceptual strategies of both the adult and the child. The perceptual connection of the dyad is clearly manifested in tracking, identifying and controlling perceptual actions as a previous phase, the emergence of compatibility.
