The goal of this research is to develop and evaluate an adaptive virtual reality (VR) system that will enable an innovative therapy for children with attention deficit on the autism spectrum. The prevalence of autism spectrum disorder (ASD) in the United State has grown significantly in recent years, and while there have been some successful efforts to address this issue by exploiting VR-based therapies, most of them merely use VR as an alternative way to simulate existing approaches. An important feature of VR technology - the ability to generate "impossible experiences" (i.e., experiences that cannot be created in the real world, such as a chair disappearing upon the user's gaze) - seems to be missing in these systems, because this feature was not available when most traditional ASD therapies were developed. The envisaged system will employ specifically designed "impossible experiences" to deliver an individualized therapy that addresses the attention deficits of children with ASD. The research will improve the learning ability for children with ASD and provide novel design guidelines for future VR systems used in ASD therapy. The PI will study research questions and develop the system incrementally. The overall logic of the system is: 1) Expose the user to a virtual environment to finish a task (e.g., listen to a virtual teacher talking); 2) Detect the user's attention with eye-tracking data and physiological signals, then remove all the detected distractions (e.g., a red mug) from the virtual environment; 3) Gradually restore all distractions into the virtual environment, expose the user to one more distraction object at a time and reinforce the correct attention. To implement this strategy, the PI will first explore attention capture in VR and strategies for reinforcement in VR through short user studies. Then, the effectiveness of the entire system will be evaluated through a six-month long, multiple-baseline design across participants study. All the studies will be conducted with K-12 students with medium to high levels of ASD.This award reflects NSF's statutory mission and has been deemed worthy of support through evaluation using the Foundation's intellectual merit and broader impacts review criteria.

这项研究的目的是开发和评估适应性虚拟现实（VR）系统，该系统将为自闭症谱系注意力不足的儿童提供创新的疗法。近年来，美国自闭症谱系障碍（ASD）的患病率显着增长，尽管通过利用基于VR的疗法进行了一些成功的努力来解决这一问题，但其中大多数仅将VR用作模拟现有方法的替代方法。 VR技术的一个重要特征 - 产生“不可能的体验”的能力（即，在现实世界中无法创建的体验，例如在用户注视的椅子上消失的椅子） - 似乎在这些系统中缺少，因为当大多数传统的ASD疗法开发出来时，此功能不可用。所设想的系统将采用专门设计的“不可能的体验”来提供个性化疗法，以解决ASD儿童的注意力缺陷。该研究将提高ASD儿童的学习能力，并为ASD治疗中使用的未来VR系统提供新颖的设计指南。 PI将研究研究问题并逐步发展系统。系统的总体逻辑是：1）将用户曝光到虚拟环境以完成任务（例如，听一位虚拟老师说话）； 2）通过眼神跟踪的数据和生理信号检测用户的注意力，然后从虚拟环境中删除所有检测到的干扰（例如，红杯）； 3）逐渐将所有注意力恢复到虚拟环境中，一次将用户暴露于另一个分心对象，并加强正确的注意。为了实施此策略，PI将首先探索VR中的注意力捕获，并通过简短的用户研究在VR中加强策略。然后，整个系统的有效性将通过参与者研究的六个月长的多基线设计进行评估。所有研究都将向具有中等至高水平的ASD的K-12学生进行。该奖项反映了NSF的法定任务，并使用基金会的知识分子优点和更广泛的影响评估标准，被认为值得通过评估来获得支持。
