In depth autism spectrum test4/27/2024 ![]() ![]() ![]() The significance of such technology is that it allows for an objective and quantitative method of recording the viewer's POG. It can be described as the process of capturing, tracking, and measuring eye movements or the absolute point of gaze (POG), which refers to the point where the eye gaze is focused in the visual scene. Further, we will support our results with a statistical analysis that will explore possible correlations between the Childhood Autism Rating Scale (CARS) and the dynamics of eye movement among participants diagnosed with ASD.Įye tracking has been used in numerous research studies. The applicability of the proposed approach will be demonstrated based on the classification accuracy. In this manner, diagnostic-related tasks can be approached as a problem of image classification or analysis. At its core, the key idea is to compactly render eye movements into an image-based format while maintaining the dynamic characteristics of eye motion (eg, velocity) using color gradients. Our approach is distinctively based on the premise that visual representations of eye-tracking recordings can effectively serve as features for discriminating individuals diagnosed with ASD. It is part of an interdisciplinary collaboration between research units of psychology and artificial intelligence at the University of Picardy Jules Verne in France. This study provides a meeting point for eye tracking and machine learning (ML) for supporting the diagnosis of ASD. In particular, these studies have highlighted social-related difficulties in children with ASD, especially when face stimuli are used (eg, in a face-to-butterfly categorical visual search task and unsuitable extraction of visual information via eye fixations for emotion recognition ). A considerable number of other psychology studies in eye tracking have been based on the particularities of eye movements in response to verbal or visual cues as signs of ASD. Eye-tracking technology has received particular attention in the ASD context since abnormalities of eye gaze have been consistently recognized as the hallmark of autism in general. Examples include magnetic resonance imaging, electroencephalography, and eye tracking, which will be considered in this study. ![]() In this respect, computer-aided technologies have been embraced to provide helpful guidance through the course of examination and assessment. Furthermore, the variation of symptoms with regard to deficits in social communication and social interaction as well as the social communication impairments and restricted, repetitive patterns of behavior make the identification of ASD more complicated to decide. The diagnosis process usually involves a set of tests that can require hours of clinical examinations or is based on an interview with the parents. Įarly diagnosis may lead to early intervention, which generally proves beneficial for both the child and the family. Nevertheless, these disturbances are not better explained by intellectual disability or global developmental delay. Such troubling deficits can unfortunately place a considerable strain on their lives and their families. During naturalistic interaction, making and maintaining eye contact is not always easy or spontaneous for ASD-diagnosed individuals. Autism spectrum disorder (ASD) has been described as a pervasive developmental disorder characterized by a set of impairments including social communication problems, difficulties with reciprocal social interactions, and unusual patterns of repetitive behaviors or interests. ![]()
