社交能力障碍被认为是自闭症谱系障碍(ASD)儿童的核心缺陷。近年来，人们研究了几种辅助技术，特别是虚拟现实(VR)，以促进这一群体的社会互动。众所周知，自闭症儿童在社交互动中表现出非典型的观看模式，因此监测眼睛凝视对设计干预策略是有价值的。虽然一些研究已经使用眼睛跟踪技术来监控眼睛凝视以进行离线分析，但还没有能够动态监控眼睛凝视并提供个性化反馈的实时系统。鉴于基于VR的社会交互的前景和实时监控眼睛凝视的有效性，本文开发了一种新颖的基于VR的动态眼动跟踪系统。这个系统被称为基于视线敏感的自适应响应技术的虚拟交互系统(VIGART)，能够在基于VR的交互过程中根据儿童的动态凝视模式提供个性化的反馈。一项对6名患有ASD的青少年进行的可用性研究的结果被提出，该研究检验了VIGART的可接受性和有效性。在与VIGART互动时，参与者的行为观看能力和相关眼睛生理指标的变化方面的结果表明了这项新技术的潜力。
Impairments in social communication skills are thought to be core deficits in children with autism spectrum disorder (ASD). In recent years, several assistive technologies, particularly Virtual Reality (VR), have been investigated to promote social interactions in this population. It is well known that children with ASD demonstrate atypical viewing patterns during social interactions and thus monitoring eye-gaze can be valuable to design intervention strategies. While several studies have used eye-tracking technology to monitor eye-gaze for offline analysis, there exists no real-time system that can monitor eye-gaze dynamically and provide individualized feedback. Given the promise of VR-based social interaction and the usefulness of monitoring eye-gaze in real-time, a novel VR-based dynamic eye-tracking system is developed in this work. This system, called Virtual Interactive system with Gaze-sensitive Adaptive Response Technology (VIGART), is capable of delivering individualized feedback based on a child’s dynamic gaze patterns during VR-based interaction. Results from a usability study with six adolescents with ASD are presented that examines the acceptability and usefulness of VIGART. The results in terms of improvement in behavioral viewing and changes in relevant eye physiological indexes of participants while interacting with VIGART indicate the potential of this novel technology.
