Public ISBD [article]  inJournal of Autism and Developmental Disorders > 44-7 (July 2014) . - p.1641-1650 Titre : Assessing the Utility of a Virtual Environment for Enhancing Facial Affect Recognition in Adolescents with Autism Type de document : Texte imprimé et/ou numérique Auteurs : Esubalew BEKELE, Auteur ; Julie CRITTENDON, Auteur ; Zhi ZHENG, Auteur ; Amy SWANSON, Auteur ; Amy WEITLAUF, Auteur ; Zachary WARREN, Auteur ; Nilanjan SARKAR, Auteur Article en page(s) : p.1641-1650 Langues : Anglais (eng) Mots-clés : Autism spectrum disorders  Virtual reality  Facial expressions  Adaptive systems Index. décimale : PER Périodiques Résumé : Teenagers with autism spectrum disorder (ASD) and age-matched controls participated in a dynamic facial affect recognition task within a virtual reality (VR) environment. Participants identified the emotion of a facial expression displayed at varied levels of intensity by a computer generated avatar. The system assessed performance (i.e., accuracy, confidence ratings, response latency, and stimulus discrimination) as well as how participants used their gaze to process facial information using an eye tracker. Participants in both groups were similarly accurate at basic facial affect recognition at varied levels of intensity. Despite similar performance characteristics, ASD participants endorsed lower confidence in their responses and substantial variation in gaze patterns in absence of perceptual discrimination deficits. These results add support to the hypothesis that deficits in emotion and face recognition for individuals with ASD are related to fundamental differences in information processing. We discuss implications of this finding in a VR environment with regards to potential future applications and paradigms targeting not just enhanced performance, but enhanced social information processing within intelligent systems capable of adaptation to individual processing differences.

Can Robotic Interaction Improve Joint Attention Skills? / Zachary WARREN in Journal of Autism and Developmental Disorders, 45-11 (November 2015)

This pilot study investigated the application of a novel robotic interaction system capable of administering and adjusting joint attention prompts to a small group (n = 6) of children with ASD. Across a series of four sessions, children improved in their ability to orient to prompts administered by the robotic system and continued to display strong attention toward the humanoid robot over time. The results highlight both potential benefits of robotic systems for directed intervention approaches as well as potent limitations of existing humanoid robotic platforms.

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.

Pilot clinical application of an adaptive robotic system for young children with autism / Esubalew BEKELE in Autism, 18-5 (July 2014)

This pilot feasibility study evaluated the application of a novel adaptive robot-mediated system capable of both administering and automatically adjusting joint attention prompts to a small group of preschool children with autism spectrum disorders (n = 6) and a control group (n = 6). Children in both groups spent more time looking at the humanoid robot and were able to achieve a high level of accuracy across trials. However, across groups, children required higher levels of prompting to successfully orient within robot-administered trials. The results highlight both the potential benefits of closed-loop adaptive robotic systems as well as current limitations of existing humanoid-robotic platforms.
