Langues : Anglais (eng) Mots-clés : Autism Spectrum Disorder  Virtual Reality  Eye-tracking;Fixation duration Index. décimale : PER Périodiques Résumé : Children with Autism Spectrum Disorder are often characterized by deficits in social communication skills. While evidence suggests that intensive individualized interventions can improve aspects of core deficits in Autism Spectrum Disorder, at present numerous potent barriers exist related to accessing and implementing such interventions. Researchers are increasingly employing technology to develop more accessible, quantifiable, and individualized intervention tools to address core vulnerabilities related to autism. The present study describes the development and preliminary application of a Virtual Reality technology aimed at facilitating improvements in social communication skills for adolescents with autism. We present preliminary data from the usability study of this technological application for six adolescents with autism and discuss potential future development and application of adaptive Virtual Reality technology within an intervention framework.

A Physiologically Informed Virtual Reality Based Social Communication System for Individuals with Autism / Uttama LAHIRI in Journal of Autism and Developmental Disorders, 45-4 (April 2015)  

Public ISBD [article]  inJournal of Autism and Developmental Disorders > 45-4 (April 2015) . - p.919-931 Titre : A Physiologically Informed Virtual Reality Based Social Communication System for Individuals with Autism Type de document : Texte imprimé et/ou numérique Auteurs : Uttama LAHIRI, Auteur ; Esubalew BEKELE, Auteur ; Elizabeth DOHRMANN, Auteur ; Zachary WARREN, Auteur ; Nilanjan SARKAR, Auteur Article en page(s) : p.919-931 Langues : Anglais (eng) Mots-clés : ASD  Virtual-reality  Eye-tracking  Fixation duration  Pupil diameter  Blink rate Index. décimale : PER Périodiques Résumé : Clinical applications of advanced technology may hold promise for addressing impairments associated with autism spectrum disorders (ASD). This project evaluated the application of a novel physiologically responsive virtual reality based technological system for conversation skills in a group of adolescents with ASD. The system altered components of conversation based on (1) performance alone or (2) the composite effect of performance and physiological metrics of predicted engagement (e.g., gaze pattern, pupil dilation, blink rate). Participants showed improved performance and looking pattern within the physiologically sensitive system as compared to the performance based system. This suggests that physiologically informed technologies may have the potential of being an effective tool in the hands of interventionists.
