Technological innovation, particularly virtual reality (VR) and collaborative virtual environments (CVE), could offer a replicable, low cost measurement platform when endowed with intelligent agent technology and peer-based interactions. We developed and piloted a novel collaborative virtual environment and intelligent agent (CRETA) for the assessment of social communication and collaboration within system and peer interactions. The system classified user statements with moderate to high accuracies. We found moderate to high agreement in displayed communication and collaboration skills between human-human and human-agent interactions. CRETA offers a promising avenue for future development of autonomous measurement systems for ASD research.

Assessing the Utility of a Virtual Environment for Enhancing Facial Affect Recognition in Adolescents with Autism / Esubalew BEKELE in Journal of Autism and Developmental Disorders, 44-7 (July 2014)  

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.

This pilot study investigated the development and application of a novel robotic system capable of dynamic, adaptive, and autonomous interaction during imitation tasks with embedded real-time performance evaluation and feedback. The system was designed to incorporate both a humanoid robot and a human examiner. We compared child performance within system across these conditions in a sample of preschool children with ASD (n = 8) and a control sample of typically developing children (n = 8). The system was well-tolerated in the sample, children with ASD exhibited greater attention to the robotic system than the human administrator, and for children with ASD imitation performance appeared superior during the robotic interaction.

This pilot study designed and evaluated a novel technologically-mediated intelligent learning environment with relevance to early social orienting skills. The environment was endowed with the capacity to administer social orienting cues and adaptively respond to autonomous real-time measurement of performance (i.e., non-contact gaze measurement). We evaluated the system with both toddlers with ASD (n = 8) as well as typically developing infants (n = 8). Children in both groups were able to ultimately respond accurately to social prompts delivered by the technological system. Results also indicated that the system was capable of attracting and pushing toward correct performance autonomously without user intervention.

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.
