患有自闭症谱系障碍（ASD）的儿童在社交技能方面表现出严重的障碍，包括在社交互动中不典型的观看模式。最近，一些辅助技术，特别是虚拟现实（VR），已经被研究来解决这一人群的特定社会缺陷。一些研究结合了眼球注视监测机制来设计干预策略。然而，目前可用的系统设计主要是通过一个人的表现方面进行连锁学习，这提供了有限的个性化范围。本研究旨在通过开发一种新颖的基于vr的交互系统来弥合这一差距，该系统具有凝视敏感的自适应响应技术，可以无缝地将基于vr的任务与眼动追踪技术集成在一起，以智能地促进与提高社会沟通技能相关的任务的参与。具体来说，这样的系统能够通过测量实时观看模式、眼睛生理反应的细微变化以及表现指标，客观地识别和量化一个人的参与水平，从而以个性化的方式自适应地做出反应，从而提高参与者之间的社会沟通技巧。开发的系统通过对8名自闭症青少年的可用性研究进行了测试。结果表明，在基于虚拟现实的社交会话任务中，该系统具有促进社会适当机制改善社会任务绩效的潜力。
Children with autism spectrum disorder (ASD) demonstrate potent impairments in social communication skills including atypical viewing patterns during social interactions. Recently, several assistive technologies, particularly virtual reality (VR), have been investigated to address specific social deficits in this population. Some studies have coupled eye-gaze monitoring mechanisms to design intervention strategies. However, presently available systems are designed to primarily chain learning via aspects of one's performance only which affords restricted range of individualization. The presented work seeks to bridge this gap by developing a novel VR-based interactive system with Gaze-sensitive adaptive response technology that can seamlessly integrate VR-based tasks with eye-tracking techniques to intelligently facilitate engagement in tasks relevant to advancing social communication skills. Specifically, such a system is capable of objectively identifying and quantifying one's engagement level by measuring real-time viewing patterns, subtle changes in eye physiological responses, as well as performance metrics in order to adaptively respond in an individualized manner to foster improved social communication skills among the participants. The developed system was tested through a usability study with eight adolescents with ASD. The results indicate the potential of the system to promote improved social task performance along with socially-appropriate mechanisms during VR-based social conversation tasks.
